Abstract

The invention discloses a soil stabilizer, and belongs to the technical field of building materials. Waste concrete is crushed to obtain waste concrete powder, the waste concrete powder and calcium alginate liquid are stirred, mixed and filtered to obtain pretreated waste concrete powder, activated carbon and calcium hydroxide saturated solution are stirred and mixed to obtain mixed liquid, carbondioxide is led into the mixed liquid, the mixed liquid is filtered to obtain filter residues, the obtained filter residues and ethyl orthosilicate are stirred, mixed, filtered and subjected to high-temperature reaction to obtain pretreated coated activated carbon, the pretreated coated activated carbon is mixed with paraffin in a ball-milling manner to obtain modified coated activated carbon, thepretreated waste concrete powder is calcined and cooled to obtain modified waste concrete, and gypsum powder, coal ash, the calcined waste concrete, phenolic resin, Arabic gum, water, the modified coated activated carbon, curing agents and water reducing agents are stirred and mixed to obtain the soil stabilizer. The prepared soil stabilizer has the advantage that soil strength is improved.

Description

technical field [0001] The invention relates to a soil stabilizer, which belongs to the technical field of building materials. Background technique [0002] The semi-rigid base material is widely used, low in cost, high in strength, high in rigidity, good in stability and anti-scourability, and serves as the main load-bearing function of the pavement structure. However, the disadvantages of semi-rigid materials are low deformation resistance, high brittleness, and easy cracking when the humidity or temperature changes. If there is too much water loss or the temperature is too low during construction, micro-cracks or macro-cracks will occur in the base layer. After finishing the surface layer, under the repeated action of temperature and vehicle load, the cracks in the base layer will develop upward to form reflective cracks. The semi-rigid base material can give full play to its advantages only under the premise of ensuring its structural integrity. Once cracks (dry shrinka...
