Abstract

This paper examined the effect of two types of nanoparticles-titanium dioxide (TiO2) and montmorillonite (MMT) nanoclay - on the behavior of cement pastes modified with two pozzolanic materials, namely, fly Ash (FA) and recycled glass powder (GP). The compressive test was performed to assess the compressive strength; the non-evaporable water content measurement was carried out to study the hydration; and electrical resistivity measurement was conducted to investigate the transport characteristics of the cement pastes. The results indicated that the addition of the nanoparticles improved the compressive strength of the cement paste without GP or FA. It was concluded that the addition of TiO2 nanoparticles resulted in an increased electrical resistivity compared to MMT nanoparticles at late ages. Both TiO2 and MMT exhibited a similar effect on the hydration of the cement pastes.
