Influence of the Water-Resisting Property and Impermeability of Mortar by Four Kinds of Common Modifiers

Article Preview

Abstract:

The effects on the waterproofness, the flexural and compression strength of cement mortar were investigated under single mixing and complexes mixing conditions of 4 kinds of modifiers, Polycarboxylic water-reducing agent, composite waterproofing agent, Sulphoaluminate expansion agent and fly ash. The results show that it is better in improving the water-resisting property and impermeability of mortar when complexes mixing any two of the 4 kinds of modifiers than single mixing. The mortar has the best water-resisting property and impermeability with the contents of 0.75% Polycarboxylic water-reducing agent and 6% composite waterproofing agent.
