Abstract

Chemical admixtures are of paramount importance to the performance of modern cement based composites In this paper we performed a series of tests to investigate the effects of chemical admixtures on the cement asphalt mortar CA mortar i e compressive strength frost resistance permeability fatigue resistance pore structure and microstructure In particular two types of chemical admixtures were tested i e defoamer tributyl phosphate TBP and polycarboxylate superplasticizer PS The results indicate that the addition of TBP and PS eliminates big bubbles and promotes small nonconnected pores forming in matrix Besides an optimum dosage of TBP and PS may be determined with respect to the frost resistance permeability and fatigue resistance of CA mortar Further elaborative discussions are presented as well as experimental evidences from mercury intrusion porosimetry scanning electron microscopy and energy dispersive spectroscopy
