Alkali-Aggregate Reactivity Apparatus

Alkali-Aggregate Reactivity Apparatus — Aggregate Testing Equipment

Alkali-silica reaction can crack concrete years after construction, so new aggregate sources for dams, bridges and pavements are screened before use. We supply length comparators, accelerated mortar bar baths, concrete prism storage containers, gang moulds for bars and prisms, and a chemical method reaction vessel set. Whether you need a 14-day screening result or a one-year prism test decides the equipment. The range covers ASTM C1260, ASTM C1293 and ASTM C490, with IS 2386 (Part 7) for the chemical method.
