Making full use of micro silica fume concrete early strength, high strength, wear resistance, can build the high grade highway, airport runway, highway tunnel and road repair projects. The construction of roads with silica fume can achieve 25Mpa compressive strength for 12 hours, improve 1 times of abrasion resistance, and 24 hours compressive strength up to 37Mpa, exceeds the design requirement of C20 concrete.
