This chapter on Polymer Modified Concrete and Mortar is a new contribution to ASTM STP 169. In January 1987, a Task Group was first formed in Subcommittee C09.03.18 (C09.25) due to the need identified for standards development in the area of Polymer Modified Cementitious materials. This Task Group started the process, and then in June of 1989 this activity was organized under a new subcommittee, C09.03.19 (C09.44) where the work continues. Membership in this subcommittee has grown to 47. This group is working on developing specifications and test methods pertaining to the use of latexes and redispersible dry polymers as modifiers for hydraulic cement concrete and mortars. These polymer modifiers mainly contribute to adhesion, water resistance, reduced permeability, and increased durability. Polymer modifiers are used in a variety of applications, such as, patching compounds, stucco, ceramic tile thin sets and grouts, and bridge deck overlays. The first ASTM sponsored Symposium on Polymer Modified Concrete and Mortar was held in Louisville in June of 1992. A second symposium is in the planning stages for 1995.
