Experimental study about the improvement of the mechanical properties of a concrete cobble using recyclable additives

Abstract

This study presents an experimental study to improve the mechanical properties of a concrete cobble using statistical software. First, an experimental design was carried out using a statistical software to obtain the different mixtures of cement with additives such as clay and ashes from ceramic kilns and then optimize the number of tests to evaluate the mechanical properties of a cobble block with different percentages of additives. Finally, the results have shown that with a mixture composed of 93.3% of concrete, 3.33% of clay, and 3.33% of ashes, it was possible to obtain the highest compressive strength with 99% compliance.
