The influence of different amount of silica fume, fly ash and mineral powder on the strength and fluidity of grouting materials of light wallboard is analyzed by control variable method,and then the optimal proportion is obtained by orthogonal test. The results show that the effect of mineral admixtures on the initial fluidity of grouting materials is silica fume>fly ash>mineral powder, and the effect on the fluidity of 30 min is silica fume=mineral powder>fly ash,when the combination of mineral admixtures is 15% fly ash+10% mineral powder+5% silica fume, the strength and fluidity of grouting materials reach the maximum value. The developed lightweight wall panel grouting material is superior to the original special grouting material. [ABSTRACT FROM AUTHOR] |
