Influence of water/cement ratio on mechanical strength of concrete with partial addition of fly ash and hydrated lime
(Journal of Physics: Conference Series, 2019-11-29)
Three mixtures were made for conventional concrete with different additions of cement, 300 kg/m3, 350 kg/m3 and 400 kg/m3, being these the 3 designs of mixtures more used for the elaboration of simple concretes. For each ...
Substitution of natural stony material aggregates in conventional 17.5 mpa non-structural concrete mixtures by means of percentage addition of hospital solid waste
(Contemporary Engineering Sciences, 2018-11-29)
An experimental character research was carried out. A conventional concrete
mixture was made with the mechanical resistance to compression of 17.5 Mpa.
The materials used in the concrete mixture were analyzed and selected ...
