摘要
特种超细矿物掺合料微珠能够应用于C50、C55商品混凝土中，用量为30-40kg／m^3。等量取代水泥时，微珠混凝土较普通混凝土配合比降低了水泥用量及胶凝材料总量，能降低混凝土的粘度，提高混凝土的强度，降低成本。C50、C55微珠混凝土用水量为145-150kg／m^3，采用C50、C55微珠专用外加剂，推荐掺量1．9％。
New special superfine mineral admixture beads can be used in C50, C55 commodity concrete, the amount is 30-40kg/m3 replacing the same amount of cement. Compared with ordinary concrete, it reduces the total amount of cement and cementitious materials, reduces the viscosity of the concrete, improves the strength of concrete and reduces costs. C50, C55 beads concrete water consumption is 145 -150kg/m3, using C50, C55 beads special additive, recommended dosage is 1.9%.
