Concrete aggregate "BM Crushed Stone 2005 / BM Crushed Sand"

Aggregates for concrete that improve durability by reducing the unit water content of ready-mixed concrete.

"BM Crushed Stone 2005 and BM Crushed Sand" are concrete aggregates that have undergone crushing and grinding using a dedicated ball mill, significantly improving their particle shape. Aggregates produced by the dedicated ball mill closely resemble the properties of natural gravel, have a high packing density, and exhibit good fluidity, which is expected to enhance the durability of concrete by reducing the amount of water used. 【Features】 - The aggregates are crushed, washed, and have their corners rounded and surfaces smoothed by the dedicated ball mill. - After surface polishing of the crushed stone, the classified particle size of 20 to 5 mm becomes BM Crushed Stone 2005, with a packing density improved to about 62%. - The classified particle size of 5 mm and under is further polished by the dedicated ball mill, resulting in BM Crushed Sand, which has performance comparable to natural sand. *This product is available in the Kyushu area.
