摘要
本文研究了矿渣掺量不同的水泥在气冷水融快速冻融条件下的抗冻性。试验表明,矿渣掺量在35%以内时,矿渣掺量对水泥抗冻性影响不大,但矿渣掺量超过35%,抗冻性明显下降。孔结构试验也证实,对抗冻性起重要作用的50nm-100nm孔和平均孔径在矿渣掺量35%左右都有最低点。
In this paper, the influence of slag quantity on frost-thaw performance of cement mortar under the condition of quick frost-thaw cycles. The test result showed that, if the slag quantity under 35%, the slag quantity has little influence on frost-thaw performance; but when slag quantity more than 35%, frost-thaw performance of cement mortar became distinctly bad. The pore-analysis showed that, pores of 50nm^100nm and average pore-size has the low-point around slag quantity of 35%.
