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170 mm、28 d强度达100~128 MPa的超高性能混凝土。 |

Abstract:
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 effi-ciency.By using such mineral powder and other raw material available in Guangzhou area?熏super high performance concrete can be produced with 28d strength of 100~128 MPa and slump over 170 mm.
