复合水泥基-水玻璃双液注浆材料胶凝性能及抗压强度试验研究
Cementing Performance and Compressive Strength of Complex Cementitions-Sodium Silicate Two-shot Grouting Materials
摘要
Abstract
Traditional cement silicate double solution grouting material has many advantages which contain the short gel time and large early compressive strength .So this material is widely used in consolidating soft formation or plugging .Based on the traditional material , fly ash and slag in cement-based was added and a kind of new complex cementitions-sodium silicate two-shot grouting materials was put out .This new material's cementing performance and 28 d compressive strength were studied .By changing the sodium silicate content , baume and mineral admixtures to study the variation of slurry's cementing performance and 28 d compressive strength .The compressive strength of stone body is the largest when the dosage of sodium silicate is 25%.Increasing modulus of sodium silicate or cement fly ash slag which are mixed can improve the compressive strength of stone body .关键词
