The Influence of Pore Structure on the Waterproof Performance of Polymer Modified Mortar

Abstract:

This paper tested the pore structure, capillary water absorption and impermeability of cement mortars modified with three polymers respectively, establishing the relationship between the pore structure and waterproof performance. The results show that with the polymer dosage growing, especially as the polymer/cement ratio (m_p/m_c) increases from 0% to 5%, the reduction in the capillary water absorption and the penetration depth of water into mortar is significant. In the m_p/m_c range of 0%~20% the open porosity presents a gradual decrease trend. The capillary water absorption and the penetration depth of water into mortar show linear growth and exponential growth respectively with the open porosity increasing.
