REACTIONS OF POLYMER LATEXES WITH PORTLAND CEMENT CONCRETE

This paper explains the physical and chemical actions and reactions of polyvinylidene chloride and styrene-butadiene polymer latexes on the aggregate and portland cement in concrete. It also describes how the polymer particles irreversibly bond to the aggregate and cement, form a monolayer of plastic particles over their surfaces, and subsequently coalesce to form a continuous polymer phase throughout the concrete. The need for curing procedures with latex concrete different from those required for the optimum cure of conventional concrete is also discussed. These basic data are expanded to explain how polymer latexes reinforce concrete, improve its structural properties, control its elastic behavior, and greatly enhance its durability. Data are presented to describe polymer latex concrete with compressive strengths from 5,000 to 15,000 psi (34 500 to 103 000 kPa), flexural strengths from 800 to 2,000 psi (5520 to 13 800 kPa), elastic moduli from 2 to 5 x 10 to the 6th power kPa), bond strength to steel greater than 2,500 psi (17 200 kPa), and bond strength to concrete greater than 600 psi (4140 kPa) at which the concrete substrate fails. Practical applications of latex concrete over the past 20 years are described, and why the materials are ideally suited for each application is explained.
