摘要

为探索磨细高炉矿渣对水泥浆性能及其水膜厚度的影响

研究测量了30组不同水胶比、不同磨细高炉矿渣掺量的水泥–矿渣复合浆体的流动性能、黏聚性和抗压强度. 为探索浆体的流变性能控制机理

进一步测量了5组不同磨细高炉矿渣掺量水泥–矿渣复合浆体的填充密度

并基于填充密度测量结果计算出各浆体试样配比的水膜厚度

探索水膜厚度对水泥–矿渣复合浆体流变性能的影响. 实验结果表明

适量磨细高炉矿渣的掺入能提高浆体的流动性能和抗压强度

黏聚性些许减弱

最优配比磨细高炉矿渣掺量为5%

此时水泥–矿渣复合浆体综合性能最好. 磨细高炉矿渣掺入能提高胶凝材料的填充密度

水膜厚度为流动性主要控制因素

水泥浆的流动性能随水膜厚度增大而增大.

Abstract

To study the effect of ground granulated blast furnace slag (GGBS) on the flowability

cohesiveness and strength of cement paste

30 mixes of cement paste samples with different water/cementitious material ratios and different GGBS contents were measured. To reveal the flowability mechanism of GGBS cement paste

the packing density of 5 different cementitious mixes with various GGBS content was measured. The water film thickness of each cement paste mix was calculated based on the packing density test

and the effect of water film thickness on the flowability of GGBS cement paste was discussed. Results demonstrated that addition of moderate GGBS could increase the flowability and compressive strength

but impair the cohesiveness. The best overall performance of cement paste occurs when 5% GGBS is added. The addition of GGBS had positive effect on packing density of cementitious materials. The water film thickness is the major governing factor of flowability of GGBS cement paste

and the flowability of cement paste increases with the increase of water film thickness.
