ABSTRACT

The purpose of the investigation is the use of a residual material through its recovery in a concrete mixer located in the town of Ixtaczoquitlan, Ver., Mexico, to make a recycled hydraulic mortar of f´c 70 kg/cm² for masonry works, providing sustainability to the concrete mixer and to determine its compressive strength compared to a normal mortar. The methodology consists of the recovery of a sample of fine waste of concrete from the treatment plant in CAGSA (Constructoras Asociadas del Golfo S. A. de C. V.), to dry it, classify it and then make mixtures with % fine waste-% mine sand (in a percentage ratio of 10%-90%, 20%-80%, 30%-70%, 40%-60%, 50% -50% and 60% -40%), as well as, water and cement, to later compare the results against a sample control and evaluate its compressive strengths. The results of compatibility with the other materials that make up the mortar are favorable and benefit its homogeneity and fluidity. The best compression strengths are mixtures at 10% -90%, and 20% -90%. In conclusion, this residue is compatible with the materials that make up the mortar and can be used to glue partitions and masonry plaster. Within the new and relevant aspects of the study is confirmation of the use of a new mortar from fine concrete waste, mixed with andesite-type mine sand, strengthening the sustainability of the environment. It was investigated that the analyzed residues contain 90% of Calcium, which is used in the manufacture of accelerating additives for concrete, based on calcium chloride. It can be a raw material to make additives that accelerate resistance. Follow-up research is recommended regarding the slump test, fluidity, compressive strength, consistency, and water retention of this type of mortar with fine recycled aggregate.
