Solidified aeolian sand polymer preparation and performance detection method
The invention relates to the technical field of sandstorm control, in particular to a solidified aeolian sand geopolymer preparation and performance detection method which comprises the following steps: preparing a powdery mixture, namely a geopolymer, by taking NaOH solid particles with the purity of 99% or above as an alkaline activator and taking slag powder and first-grade fly ash as geopolymer precursor powder; the preparation and performance detection method of the solidified aeolian sand geopolymer has the beneficial effects that by analyzing the shear strength parameter of the solidified aeolian sand of the geopolymer in a saturated state, the mixing amount of the geopolymer mainly influences the cohesive force, and the influence on an internal friction angle is relatively small. The parameter eta/Gv can well reflect the influence of the mixing amount of the curing agent and the porosity on the strength of the cured aeolian sand, and the cohesive force and the internal friction angle of the soil sample have a power function relationship with the parameter eta/Gv.
本发明涉及风沙治理技术领域，具体为一种固化风积沙地聚合物制备及性能检测方法，包括以下步骤：采用纯度为99％以上的NaOH固体颗粒作为碱性激发剂，以矿渣粉和一级粉煤灰为地聚合物前驱体粉料，配制成粉状混合物，即为地聚合物；有益效果为：本发明提出的固化风积沙地聚合物制备及性能检测方法，通过分析饱和状态下地聚合物固化风积沙的抗剪强度参数，可知地聚合物掺量主要影响的是黏聚力，而对内摩擦角的影响较小。参数η/Gv可较好体现固化剂掺量和孔隙率对固化风积沙强度的影响，土样的黏聚力和内摩擦角均与参数η/Gv存在幂函数关系。
