Variables Affecting the pH Measurement of Cement Mortars

Abstract

A quantitative pH measuring method has been used to measure the pH of pure and blended cement mortars. The blended cement mortars incorporating supplementary cementitious materials (SCMs) such as fly ash (FA), ground granulated ballast furnace slag (GGBFS) and palm oil fuel ash (POFA) were used. Moreover, different variables affecting the pH values of CBMs such as temperature of sample solution, quantity of sample powder, dilution ratio and temporary storage of sample during pH measuring process have been studied for all cement mortars.

Keywords
