摘要
某些矿物微粉具有强烈的减水作用 ,且可在化学减水剂无能为力的超低水灰比条件下发挥出来 ,利用这些矿物微粉以及广州地区容易获得的其他原材料 ,可稳定地制备坍落度大于170mm、28d强度达100~128MPa的超高性能混凝土。
Some mineral powder has intensive water-reducing function in batching concrete.It may be efficient in the case of over-low water cement mixing ratio where chemical water-reducing agent loses its efficiency.By using such mineral powder and other raw material available in Guangzhou area,super high performance concrete can be produced with 28d strength of 100~128 MPa and slump over 170 mm.
