Abstract

The invention discloses an enhancing agent for consolidating tailing of iron core, which is composed of 7-12% of sodium methylsilanolate, 8-13% of acetonformaldehyde condensate sulfonate (USZ), 10-25% of NaSO4, 1-5% of succinate sodium, 5-15% of sodium aluminate and 50% of water. The product has no harm to human body, livestock and plants. The soil solidified intensifier has high initial strength, good cracking resistance and freeze resistance, the seven-day unconfined compression strength is larger than or equal to 3.0Mpa, the anti-bending tensile strength is 0.50-0.62Mpa, the modulus of resilience is 1,300-1,700Mpa, and the water stability is 90-95%. The intensifier has less usage and large supply diameter, facilitates construction and can reduce construction cost.

Description

technical field [0001] The invention belongs to a solidification enhancer using iron ore tailings as road construction materials, which is suitable for roadbed construction in road engineering. It has the advantages of improving the mechanical properties of the subgrade and water resistance. Background technique [0002] The reinforcing agent of the invention is a novel chemical material used to improve iron ore tailings as road construction. It can significantly improve the mechanical properties of iron ore tailings and cement consolidated roadbed with large pores and poor gradation. Referring to the road construction technology of sandy soil and gravel soil, the soil solidification technology can be divided into the following categories: [0003] (1) Inorganic binder [0004] Inorganic binder is a traditional solidifying material, including cement, lime and fly ash, etc. They can be used alone or mixed in a certain proportion. Cement, lime, and fly ash are widely used ...
