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.
