Expansive soil ash-doped improver and improvement method thereof
The invention discloses an expansive soil ash-doped improver and an improvement method thereof and relates to the technical field of civil engineering materials. In the prior art, when lime and cementare used for improving expansive soil, the improver can cause emission of a large amount of greenhouse gas in the production process, and serious burden is caused to the environment. The invention just aims to solve the above problem in the prior art. The expansive soil improver is technically characterized by comprising 3-6% of coal gangue, 3-7% of fly ash, 2-5% of steel slag, 60-80% of bacillusmegatherium liquid and 60-80% of cementing liquid based on the total weight of 100% of dry expansive soil to be improved by the expansive soil improver. According to the technical schemes of the invention, industrial waste residue components are subjected to a series of physical and chemical actions through microorganisms to generate gel product connection, wrap particles and fill gaps, so that astable soil body structure is formed, an improvement effect is greatly improved. The expansive soil improver and the method are of significance in resource reutilization and environment protection.
本申请公开了一种膨胀土掺灰改良剂及其改良方法，涉及土木工程材料技术领域，旨在解决相关技术中使用石灰和水泥改良膨胀土，其改良剂在生产过程中会造成大量温室气体的排放，对环境造成严重负担的问题，其技术要点在于以该膨胀土改良剂所欲改良的干膨胀土的总重量为100％计，其包括3‑6％煤矸石、3‑7％粉煤灰、2‑5％钢渣、60‑80％巨大芽孢杆菌菌液及60‑80％胶结液。本方案中工业废渣组分通过微生物进行一系列物理化学作用，产生胶凝产物联结、包裹颗粒并填充空隙，形成稳定的土体结构，大大提高了改良效果的同时，提高改良效果，具有资源再利用和保护环境的意义。
