CERATECH has revealed that test results has proved its KEMROK cement can bear acid attack. The innovative cement significantly reduces product downtime and maintenance expenditures. KEMROK cement demonstrates better durability to Portland cement in acid resistance tests. In tests conducted as per the guidelines of ASTM C-267, technicians immersed samples of concrete, one made with KEMROK cement and another one with Portland cement, in different acid solutions, including hydrochloric, acetic, phosphoric and sulfuric acid. After exposure to 93 per cent sulfuric acid for 84 days, the concrete made with KEMROK cement had lost just above 1 per cent of its mass and 5 per cent of its compressive strength, while the loss on Portland cement-based concrete’s mass was more than 4 per cent and strength was 18 per cent. Moreover, the Portland cement concrete had constantly deteriorated, while deterioration to KEMROK cement concrete almost ended after a month. As concrete is continually in contact with sulfuric acid in their processing facilities, the test on sulfuric acid durability is critical for petrochemical manufacturers. KEMROK cement concrete had demonstrated superior durability than the Portland cement concrete in exposure to other acids.As all cement products of CERATECH, including KEMROK are produced from 95 per cent recycled materials and 5 per cent renewable materials in a nearly carbon-zero process, they are ideal for companies involved in green building practices.Founded in 2001, CERATECH has pioneered and commercialized a high performance green sustainable alternative to traditional Portland cement technology. Based in Alexandria, Virginia with Research and Development in Baltimore, Maryland, CERATECH has grown from offering a broad range of packaged repair mortars and concrete mixes to high volume, high performance bulk cements for typical concrete construction and demanding industrial and military applications.The environmental implications for CERATECH cement technology are profound. CERATECH cement is comprised of nearly 100 per cent recycled waste streams and other green sustainable components eliminating a ton of CO2 for every ton produced when compared with traditional Portland cement manufacturing.
