Figure 2 shows that the loss of compressive strength respect to the control concrete was reduced. The compressive strength values improved when the SW were subjected to crushing and burned processes. On the contrary, the values of tensile splitting strength were higher in the SCC manufactured with processed SW compared to the Control.
Respecting the durability of concrete manufactured with SW, the results showed an improved performance compared to conventional SCC. The water absorption results were increased with the use of SW, mainly due to the absorption that characterizes this material. However, lower results were obtained regarding the penetration of chloride ion. The use of SW as a replacement of limy filler improves certain durability parameters obtained for SCC manufactured.
