Subgrade improvement by the replacement of conventional stone aggregate by biosanitary waste treated
(Journal of Physics: Conference Series, 2019-09-30)
An experimental investigation was made in search of the improvement of the material used for the conformation of the subgrade in pavements. Three separate excavations were carried out 150 m apart in a 510 m stretch located ...
Determination of the quality of coarse aggregates for the elaboration of concrete mixes from 3 water sources in the City of Cucuta-Colombia
(Journal of Physics: Conference Series, 2018-12-07)
A comparative analysis was performed on the mineral material extracted from 3 water sources in the city of Cucuta, from the rivers Tachira, Pamplonita and Zulia to determine the viability of their incorporation in the ...
Application of LEAN tool "line balancing" to determine the productivity of workforce in activities of plastering and internal detailing in two-story houses made of masonry
(Contemporary Engineering Sciences, 2018-11-26)
The finishing work of construction represents an aggregated value that makes the
difference when a client is deciding to buy a house. The stipulated costs for
plastering and detail activities for houses, in occasions, ...
Verification of compression resistance between a conventional concrete and its addition of 5, 10 and 15% in volume of fly ash replacing fine aggregate
(Journal of Physics: Conference Series, 2018-12-07)
A comparative analysis was performed with regarding the compression resistance of a conventional concrete mixture and its experimental addition of 5, 10 and 15% of fly ash with respect to the volume of its fine aggregate. ...
Incidence of the lean philosophy construction in the productivity and analysis of processes in internal finishes in masonry living quarters in the construction projects: case-residential complex Callejas-Cucuta-Colombia
(Contemporary Engineering Sciences, 2018-08-30)
The technical supervision in the construction projects is of special importance for
