This is manifested in NM-10% where the previously
observed larger and deeper voids inNMappeared to become smaller
and shallow without a continuous bridging across the cement and
aggregate particles. Meanwhile, denser features exhibited by the
modified mixes have indicated suitable qualities for raising level
of restriction to fluid flow into and within these phases. Thus, the latex
performs its action by blocking the access of the moisture which
normally transports the chemical agents into the concrete matrix.
