Thiết kế cấp phối hỗn hợp SILICA-SOL - Xi măng để xử lý khẩn cấp sự cố thấm nền cát công trình thủy lợi

Abstract

In this paper, the author designed the Silica-Sol - Cement mixed with construction sand to study the emergency waterproofing ability and long-term working conditions of the sand-based waterproofing membrane for irrigation works. The laboratory experiment results show that when the ratio of Silicate-cement (S/C) reaches 40% to 60%, the ratio of water-cement (W/C) is taken in the range of 50% to 70%, and the mixture of silica-sol-Cement (S-S-C) and sand which is recommended to use in the range of 30% - 50% to ensure construction conditions and emergency waterproofing by chemical grouting solutions. The research results of this paper will make an important contribution to strengthening the theoretical basis for the widespread application of chemical grouting solutions.
