Resumen
The self compacting concrete has proved an advantage compared to conventional
concrete, taking into account that can demonstrate a reduction in the overall costs of the work. In its composition, has the same materials used in conventional concrete,
however have to have a higher mortar content. In view of the scarcity of natural sand deposits and the price in this market, it has been proposed to find what the lowest
amount of additive used in mortars with sand crushing to self compacting concrete,
through scattering assay. Being used mortars with different compositions of natural
sand and sand crushing has a minimum amount of additive used in 0.3%, where all
mortars met the criteria established scattering.
