Colmenares Uribe, Andrea Paola | 2020-01-01

The ceramics industry in Norte de Santander is recognized for the quality of the raw material that the products offer. However, the guild has limited itself to the mass production of units to satisfy the construction market, leaving aside research and innovation fields to develop new proposals. The characterization of multiperforated brick MB at laboratory level is a thermal and technical referent of a conventional product and positioned in the construction world. The product was developed on a laboratory scale by extrusion in clay and coffee dust in the CIMAC Ceramic Materials Research Center from the Francisco de Paula Santander University, in order to characterize the MB physical and mechanical properties such as linear contraction, mass losses, determination of efflorescence, resistance to compression, dimensions, water absorption, initial rate of capillarity, porosity and apparent specific weight at the laboratory level. In parallel, it was validated thermally through simulations using the finite element method performed in the ANSYS R16 software to identify the energy behavior by transfer and heat fluxes. This research is the starting point for future projects focused on the design of ceramic products. The results provide technical and thermal data to develop new innovative products that contribute to sustainability

This work is based on previous studies that explores the partitions structure morphology in Blocks H10 establishing a model of 6 horizontal cavities for low thermal conductivity and having oblique geometry partitions to interrupt heat conduction by direct thermal bridge inside of the constructive unit called Form-C, which is taken as the object of analysis, adding 5% organic coffee cisco additive in the 95% clay mixture to increase the porosity with a proportion that does not affect the deterioration of the mechanical properties and allow to optimize the thermal insulation capacity regarding to a traditional product. Methodologies: in the first phase, prototypes of Block H10 with Form-A are manufactured by extrusion at the laboratory level as a comparative witness of the properties of a standard piece and Form-C as a piece with thermo-insulating strategies to execute physical-ceramic, geometric evaluations of mechanical resistance and water absorption applying the Norma Técnica Colombiana 4017 for masonry units. In the second stage, simulations of temperature distribution and heat flow are prepared by finite element method in ANSYS R16 software to determine the incidence of the variables in the mixture on heat transfer. The results obtained from thermal simulations show an energy decrease of 1.5 °C on average in relation to Form-A. In conclusion, the use of agro industrial scraps and the implementation of passive design techniques in the ceramic piece generate added value in a product that can be industrialized with improvements in technological properties from a thermal efficiency perspective in construction ceramics.

The traditional blocks of baked clay represent 15% of the total production of the ceramics cluster in the Norte de Santander region, with a product typology whose dimensions, shape, weight and price are the most demanded of the market. Its positioning becomes a molding element of the materiality of the architectural covering in the metropolitan area of San José de Cúcuta. This research focuses on the study of two of the most economical and used products in building materials constructions in the city: the blocks manufactured by extruded H-10 of 6 rectangular cavities with market dimensions L: 300 mm, W: 100 mm, H: 200 mm and H-15 of 9 rectangular cavities of size L: 300 mm, W: 150 mm, H: 200 mm and seeks to report its physical-mechanical characteristics to compare the impact of the variables in the units thermal behavior in the enclosure system. This work is carried out by applying 2 methods: in the first phase tests are carried out at the laboratory level using the Norma Técnica Colombiana 4017 and the Norma Técnica Colombiana 4205 to determine the qualitative properties of the building units in each format, and a simulation of temperature distribution and heat flux by finite element method in software ANSYS R16 evaluating the incidence of variables in the heat transfer in a traditional masonry system, evaluating the thermal performance in extreme temperature conditions of 33 °C typical of the region. The results show a difference of 0.709 °C between the thermal behavior between the formats, with a reduction of final thermal energy by the approximate increase of 50 mm in the thickness, this variant presents an opportunity of development to minimize the impacts of the loads of temperature in the envelope, favorable for warm tropical climates.

Colmenares Uribe, Andrea Paola | 2019-11-29

The demand for cooling and heating systems to adapt spaces is a critical environmental problem due to the high energy consumption required for its operation. For this reason, the offer of products for architectural facades should consider constructive solutions that mitigate the heating of buildings. Thermal behavior of building materials is an elementary factor in the energy consumption of buildings. This paper presents the comparative thermal analysis of 4 ceramic product designs for masonry, of which, one represents the traditional multi perforated brick and the others, are proposed to prove whether shape affects the heat transfer processes. The research methodology is divided into 2 stages: product design and thermal validation by transfer and heat fluxes in the ANSYS R16 software using the finite element method. For the design process, modification of the internal cells and elimination of the thermal bridge was implemented. Simulations were configured under the highest values of solar radiation recorded in the city of San José de Cúcuta, Colombia to know the products performance in the most extreme conditions of the city. The results indicate that design varies energy performance of the product, since it reduces the temperature of the inner surface to 1.23 °C or increase it to 2.25 °C. The results show that the modification of cells distribution and elimination of thermal bridges are passive strategies for the reduction of heat transfer in the design of ceramic product for masonry. This research is a breakthrough for future research that develops constructive units focused on improving the quality of life of people from thermal comfort, energy efficiency and the use of local resources and technologies.

Sanchez Molina, Jorge | 2020-12-09

The role of facades is fundamental to determine the energy performance of a building. According to the properties of construction elements, the heat transfer towards the interior can be strategically controlled to avoid increases in energy demand by the cooling system. The development of insulating products can solve this problem. In Norte de Santander, Colombia, the thriving clay industry is based on raw material quality. This paper designs and validates the thermal behavior of two proposed ventilated bricks, called eco Design. The thermal validation was fulfilled using the ANSYS R16 software to simulate the transfer and heat fluxes according to shape and material. The best performance was achieved by an extruded process to determine the mechanical properties on a laboratory scale in different mixtures with technological additives. The results show that the ventilated air chamber can reduce the inner surface temperature up to 45.5 °F. Nevertheless, the strength of these new products is considerably reduced compared to traditional multi-perforated brick.

The products and construction systems for facades regulate energy transfer in the architectural envelopes. Therefore, this paper developed an exploration of types of ventilated air chambers to improve thermal efficiency of brick for masonry walls in fired clay, taking into account their role in buildings. The methodology involves three fundamental stages: design, simulation and analysis of results. The design stage proposes 3 brick typologies with ventilated air chamber. The second stage simulates the behavior of the heat transfer and heat fluxes of the models in extreme climatic conditions of San Jose de Cucuta, Colombia, in September in Ansys software through the finite element method. Finally, the analysis of results studies the relationship between the incorporation of the ventilated chamber, shape of the product and heat transfer of proposed models, in comparison with the multi-perforated brick. The results indicate that thermal benefit varies between 2.52 °C and 3.64 °C in the interior surfaces of proposed bricks. Moreover, incorporation of ventilated air chamber mitigates heat transfer and reduces energy concentration in the interior sides of new bricks design. In conclusion, innovation in brick design proves that new forms proposition generates added values such as thermal benefits related to comfort. This aspect is important to consider because it establishes a transformative perspective for brick industry through an innovative market that is committed to sustainability of architectural envelopes in order to reduce energy consumption of buildings.

...
Sanchez Molina, Jorge | 2020-09

Industrial organic waste reuse in product manufacturing processes is a strategy that strengthens the circular economy. Thanks to materials science, the coffee husk is considered a sustainable alternative that promotes industrial processes optimization in the ceramic industry and contributes to the energy efficiency of buildings. This paper summarizes the behavior of H10 blocks on a laboratory scale in 2 mixtures of clay and coffee husk fired in 3 different temperatures: 900 °C, 1000 °C, and 1100 °C, at the "Centro de Investigación en Materiales Cerámicos, Universidad Francisco de Paula Santander", Colombia; and evaluates the relationship of physical and mechanical properties with thermal behavior by heat transfer and heat fluxes, simulated in the analysis system software through the finite element method. The results support the improvement of thermal insulation capacity. Due to this, coffee husk combustion generates internal air chambers that increase the porosity of the product. In spite of, physical and mechanical properties contrast thermal benefits with increasing water absorption percentages and thus decreasing the compressive strength of samples. In conclusion, new materials development is a technological advance that expands possibilities to create new solutions for buildings and even improves standardized designs in the ceramic industry.

Colmenares Uribe, Andrea Paola | 2020-10

The generation of new building materials responds to the reduction of energy consumption and regulation of building interior temperatures as strategy to improve energy efficiency in materials engineering and architecture. This research focuses on the study of the rice husk incidence on the physical, mechanical and thermal properties of H10 block manufactured in the metropolitan area of San José de Cúcuta, Colombia. The methodology consists in 4 stages: In first instance, raw material characterization to identify chemical, structural and morphological components of clay and rice husk. Then, H10 blocks manufacturing in 2 clay mixtures, fired at 900 °C, 1000 °C and 1100 °C. Likewise, tests of manufactured samples to analyze its physical and mechanical properties. Parallel to the manufacturing process, transfer and heat fluxes simulations to evaluate surface temperatures and energy concentration of H10 block. In conclusion, rice husk acts as a technological nutrient added to clay mixture and strengthens thermal and insulating capacity of blocks. Nevertheless, the presence of rice husk in clay mixtures increases water absorption capacity of the products, as the percentage of husk increases. And therefore, the compressive strength decreases, which is a factor to consider for the constructive application of H10 block.

Sanchez Molina, Jorge | 2021-08-09

The reutilization of agro-industrial waste in the manufacture of fired clay products is a sustainable strategy that aims at the circular economy. The most known waste in Norte de Santander, Colombia, are coffee husk and rice husk. For this reason, this research studies the thermal impact of their insulating properties in traditional masonry products made of fired clay to be considered as insulating additives. The methodology involves the simulation of heat transfer and heat flux of the multiperforated brick and H10 block manufactured in mixtures of 100% clay and 95% clay and 5% additive to wastes in North Santander, Colombia, in the software ANSYS under the finite element method in extreme conditions of San José de Cúcuta. The results demonstrate that the residues of rice husk and coffee husk act as insulating technological nutrients with a reduction of temperatures of the interior surfaces of the products between 0.22 °C and 0.88 °C, respectively. The reutilization of residual raw materials from alternate construction industries is a sustainable consideration to evaluate new possibilities for the manufacture of products with less embedded energy and, therefore, with a lower carbon footprint than traditional fired clay products.
