Technologies in concrete are rapidly advancing. New additives are introduced every year that make concrete stronger, lighter, more or less flexible. To take advantage of the best qualities of the new mixes, technical evaluation and advice is crucial.
Testing concrete fibers: steel, glass, natural and synthetic
Element technicians have several methods for testing concrete admixtures and fibers. For concrete fibers, we analyze steel, glass, natural and synthetic fibers. These methods are in compliance with ASTM C1116 and ASTM C1399, as well as ICC-ES AC32, ICC-ES AC208, and ICC-ES AC217.
Testing concrete admixtures to ASTM standards
Typical tests for concrete admixtures are conducted in accordance with ASTM C494 and ASTM C260. We test air entraining, water reducing, accelerating, and retarding admixtures for various performance properties.
