Abstract

The invention discloses a solid addition agent for solidifying soil into an ecological road, and a preparation process thereof. The solid addition agent is prepared from the following raw materials in parts by mass: 8 to 10 parts of potassium methyl silicate, 2 to 3 parts of polyacrylamide, 10 to 15 parts of polyvinyl alcohol, 2 to 5 parts of ammonium persulfate, 3 to 5 parts of glycerin, 3 to 5 parts of hydroxypropyl methyl cellulose, 10 to 20 parts of sodium hydroxide, 2 to 3 parts of ethylene glycol, 2 to 3 parts of texanol, 28 to 40 parts of deionized water, and 3 to 8 parts of aluminum sulfate. The preparation process comprises the steps of uniformly mixing the potassium methyl silicate, the hydroxypropyl methyl cellulose, the polyacrylamide, the deionized water, the glycerin, the ammonium persulfate, the aluminum sulfate, the polyvinyl alcohol and the sodium hydroxide at room temperature; steaming and stirring; adding the ethylene glycol and the texanol, stirring, filtering and discharging. The solid addition agent provided by the invention can change the property of soil so as to play a role in stabilizing and hardening the soil, is convenient to construct, and can enable the soil to be easy to solidify, and the bearing capacity and the freezing resistance are greatly improved after stabilizing treatment.

Description

technical field [0001] The invention relates to the technical fields of ecological garden landscape road construction and road subgrade engineering, in particular to a soil admixture for solidifying soil into an ecological road and a preparation process thereof. Background technique [0002] Soil stabilization and curing agent is made of a variety of inorganic materials or organic materials after a certain production process, and is directly used as an engineering material as a road structure layer. General soil stabilizers and curing agents can directly cement the surface of soil particles in the soil at room temperature or can react with clay minerals to form gelling substances, which can change the composition of the soil and the engineering properties of the soil, thereby improving soil quality. body strength. [0003] At present, there are a lot of researches on soil curing agents in various countries, and there are various soil curing agent stabilizers on the market. ...
