Jin source licensing is the use of high-performance dry kiln expanders (my company has the largest, Nissan 1000 tons of clinker production line of high-performance expansion) expansion of clinker production of high-performance, through compliance with IS0 9001-2000 quality management system certified production system from the processing of high-performance concrete expansion. Using the product can solve concrete cracking and leaking problems arising due to shrinkage; Third, the product performance: Jin source licensing high-performance expansion agent by hydration reaction with cement, water in the concrete to form crystals of contraction and expansion, compensation concrete products characteristics are as follows: 1, excellent expansion capability, expansion rate far exceeds the national standard, can fully compensate for concrete shrinkage; 2, to improve water resistance of concrete itself, cancel outdoor water; 3, for the long concrete structure, can achieve a one-time casting, simplify construction processes, shorten the construction period; 4, reduce shrinkage, increase the density of concrete, cracks in the concrete to solve the fundamental, can greatly improve the durability of concrete; details visit our website: http: //www.sanyuantc.com
