Soil stabilizer for reinforcing roadbed base

Abstract

The invention relates to soil stabilizer for reinforcing a roadbed base. According to the formula, the soil stabilizer is prepared from, by weight, 35-45 parts of cement, 10-18 parts of fly ash, 7-12 parts of quick lime, 12-18 parts of calcined gypsum, 6-15 parts of sodium silicate, 4-8 parts of chloride and 6-15 parts of sulfate. The soil stabilizer has the advantages of being low in price, high in reinforcing speed, good in engineering performance, economical, environmentally friendly, novel, efficient and fast, construction operation is easy, and the materials are easy to obtain; soil stabilizer can improve physical and mechanical properties and engineering properties of soil mass and enhance water stability, has high shearing strength, compressive strength, compressibility, penetration resistance, improves tenacity and water resistance, can meet the design standard requirement and is suitable for roadbed engineering construction such as roads and railways.

Description

technical field [0001] The invention relates to a soil curing agent for reinforcing roadbed bases. Background technique [0002] In roadbed construction in my country, lime stabilized bases, cement stabilized bases, lime fly ash stabilized bases, etc. are mostly used for subgrade bases. Sand, gravel, gravel, lime, cement, fly ash, etc. are used in large quantities and cost high. The strength of lime soil is slow to form, the construction progress is long, it is easy to soften, the drying shrinkage cracks are large, and the water stability is poor; the initial setting and final setting time of cement soil cannot be adjusted, and the drying shrinkage cracks are large, resulting in compression resistance, frost resistance, seepage resistance, and erosion resistance. Lime fly ash soil has low early strength and poor water stability. Contents of the invention [0003] Based on the above deficiencies, the present invention provides a soil curing agent for reinforcing the subgra...
