Abstract

The invention discloses a composite soil stabilizer. The composite soil stabilizer is prepared by adopting solid sulfur ash as a main raw material and adding ordinary Portland cement, quick lime, an excitant, an early strength agent, silica fume and polyacrylamide for mixing evenly. The composite soil stabilizer is specifically prepared from the following raw materials in parts by weight: 5-15 parts of ordinary Portland cement, 60-90 parts of solid sulfur ashes, 3-8 parts of an excitant, 1-5 parts of early strength agent, 1-3 parts of silica fume, 2-6 parts of quick lime and 0.02-0.1 part of polyacrylamide. The solid sulfur ash of a circulating fluidized bed of a power plant is utilized as the main raw material, and active components such as silicon dioxide and aluminum oxide in the solid sulfur ash are fully utilized, so that wastes are changed into treasures. The composite soil stabilizer is capable of significantly improving a roadbed structure and strengthening the strength of a roadbed, the unconfined compressive strength can be improved by over 30% under the condition of not changing the construction condition, the service life of the roadbed is prolonged, and the road construction cost is reduced.

Description

technical field [0001] The invention relates to a soil curing agent, in particular to a composite soil curing agent, which belongs to the field of building materials. Background technique [0002] Circulating fluidized bed coal combustion technology is a new generation of clean coal combustion technology, which can burn almost all coal (such as peat, lignite, bituminous coal, lean coal, anthracite, and coal slime from coal washing plants), coal gangue, coke, oil pages Rock, etc., and can achieve a combustion efficiency of 98% to 99%. Its main feature is that fuel and sulfur-fixing agent are added to the boiler at the same time, and the desulfurization reaction time is long after repeated cycles in the boiler, and the desulfurization rate is relatively high, generally above 90%. This technology has obvious advantages in environmental protection and utilization of low-quality coal, and is considered to be a clean coal-fired technology suitable for my country's national condit...
