HP CURING MEMBRANES

Solvent-based acrylic membranes for use in concrete curing are established and effective. This article considers the curing proc and shows how water-borne acrylic polymers may now be just as effective for formulating high-performance concrete curing compou and have the added advantage of better job-site safety and environmental impact. Proper hydrating conditions create the opti environment to promote the hardening of freshly cast concrete. Pr curing involves controlling humidity, to prevent moisture loss fr fresh concrete, and concrete temperature and temperature gradient Curing methods include: (1) physical barriers to prevent evaporat (2) membrane curing compounds; and (3) water spraying and immersi The historical performance standard for concrete curing membranes been ASTM C-309, focusing on water retention. In 1996, ASTM C-131 was formalised to specify performance requirements for cure and s coatings. Curing compounds, based on water-borne acrylic polymers pose fewer problems for worker health and safety, and are significantly less polluting than curing compounds supplied in organic solvents. The article reports briefly on a test evaluatin three different acrylic binders designed for use as curing membra
