Abstract


The Physiochemical and Mechanical Properties of cement pastes containing synthetic surfactants as air entraining agents are investigated by adding different percentages of each of the nonionic surfactant Luramide 11 (LM) and the anionic surfactant Sodium lauryl benzene sulfonate (SLBS) to some Portland cement pastes. The influence of the different surfactants concentrations and the mixing times on the air content of the pastes and accordingly the bulk density, compressive strength and microstructure of the hardened cement specimens is discussed. The optimal level of factors to achieve the desired goals is determined. The results show that LM is more preferable than SLBS in most cases.
