Abstract

The invention relates to a high-performance sand-soil consolidation material, as well as a preparation method and a using method thereof. The high-performance sand-soil consolidation material belongs to a mortar composition and is characterized by comprising the following raw materials in parts by weight: 5-40 parts of cement clinker, 3-6 parts of gypsum, 4-10 parts of alkali additive, 0.5-6 parts of compound activating agent, 1-4 parts of early strength agent, 2-10 parts of mineral activating agent, 3-8 parts of expansion agent and 22-77 parts of micro-powder formed by fine grinding of blast furnace water-quenched slag. The invention provides the high-performance sand-soil consolidation material which has the advantages of simple operation, convenient construction, good water resistance, fast consolidation, high early strength, stable improvement of post-strength, resistance to erosion of underground inorganic salt water, excellent anti-seepage performance and low production cost, as well as the preparation method and the using method thereof. The high-performance sand-soil consolidation material is suitable for consolidating mine tailings, natural weathered sand, fly ash, gravel, stone chips, stone powder, soil, sludge, construction waste, coal gangue and phosphorus slag into a solid material, and can be used for laying a subgrade, constructing a wall body and constructing a site foundation.

Description

technical field [0001] The invention is a high-performance sand-soil consolidation material and its preparation method and application method. It belongs to mortar composition. Background technique [0002] Sand consolidation materials are widely used in cave filling and reinforcement in mining areas, building foundation pit filling, dam body and slope protection reinforcement filling in water conservancy projects, and foundation construction of freight yards, pavement foundations, and open-air sports fields. [0003] The sand and soil consolidation materials in the prior art often adopt lime and cement as the consolidation materials for solidifying sand and soil. Although it can achieve the strength required by the design, it has poor water resistance, anti-seepage and corrosion resistance, slow curing, low early strength, especially poor resistance to underground inorganic salt water erosion, and low strength. The stringent requirements of strength, corrosion resistance,...
