EFFECT OF INCORPORATING FLUE GAS DESULPHURISATION (FGD) WASTE ON POROSITY AND PORE SIZE DISTRIBUTION OF CEMENT PASTE

摘要：

This paper reports results on the porosity and pore size distribution of cement paste containing varying amounts of simulated desulphurised waste (SDW). The water to binder ratio was 0.5. The binder consists of cement and SDW. The SDW is a combination of fly ash and gypsum ranging from 0～100％. Cement in the pastes was partially replaced with 25％ SDW (by weight). The porosity and pore size distribution of cement pastes at 28 days of curing is reported. Increasing the amount of gypsum up does not change the pore volume, however, there is tendency of obtaining coarser pore structure in the presence of gypsum.
