摘要：

A special water repellent for mortar is made from the combination of polyacrylamide as a principal raw material and FDN-2 as an additive. Every item of comparison test and research for the technical features of the compound water-repelling admixture (CWRA) has been carried out in building antiseepage mortar. The result shows that the main properties of the mortar have satisfied China's national standard. The permeability of mortar added with the agent has been greatly improved. The mortar has high effective penetration resistance and good workability. This paper discusses the waterproofing mechanism of the agent. (C) 2004 Elsevier Ltd. All rights reserved.
