civil engineering objective type question:

When considering the use of laterite soil as a replacement for sand in NSC and HSC within once civil engineering, which statement is accurate?

a$)$ Incorporating laterite soil improves the tensile strength of NSC but has no effect on HSC$.$

b$)$ The addition of laterite soil increases the chloride ion penetration resistance of NSC$,$ while in HSC$,$ it decreases.

c$)$ Substituting sand with laterite soil leads to a decrease in the initial setting time of both NSC and HSC$.$

d$)$ Utilizing laterite soil as a partial replacement for sand enhances the alkali$-$silica reaction potential in both NSC and HSC$.$
