Phosphoric acid-based geopolymer semi-rigid base material and application thereof
The invention discloses a phosphoric acid-based geopolymer semi-rigid base material and application thereof. The phosphoric acid-based geopolymer semi-rigid base material is specifically prepared by mixing and stirring phosphoric acid-based geopolymer neat paste and graded broken stone. The semi-rigid base material mainly comprises the following ingredients: a phosphoric acid exciting agent, silicon-aluminum solid waste and graded broken stone, wherein the molar concentration of the phosphoric acid exciting agent is 10-60%; the phosphoric acid-based geopolymer neat paste is composed of silicon-aluminum solid waste and a phosphoric acid exciting agent; the molar ratio of Si to Al in the geopolymer system is 1-4, the molar ratio of Si to P is 7-10, and the molar ratio of H2O to Si is 1-2; the mass of the phosphoric acid-based geopolymer neat paste accounts for 3-12% of the mass of the graded broken stone. According to the invention, the problems of high cost, high energy consumption, high pollution and the like in the production of a silicate system semi-rigid base material are effectively avoided, and meanwhile, the problems of poor durability and easiness in cracking of an aluminosilicate system semi-rigid base material are effectively solved.
本发明公开一种磷酸基地聚合物半刚性基层材料及其应用，具体采用磷酸基地聚合物净浆与级配碎石混合搅拌而成。半刚性基层材料主要包括以下配料：磷酸激发剂、硅铝质固体废弃物、级配碎石，其中所述磷酸激发剂的摩尔浓度为10‑60%；所述磷酸基地聚合物净浆由硅铝质固体废弃物与磷酸激发剂组成；所述地聚合物体系的Si/Al摩尔比为1‑4，Si/P摩尔比为7‑10，H2O/Si摩尔比为1‑2；所述磷酸基地聚合物净浆的质量占级配碎石质量的3‑12%。本发明有效避免了硅酸盐体系半刚性基层材料生产中的高成本、高能耗、高污染等问题，同时有效解决了硅铝酸盐体系半刚性基层材料耐久性差、易开裂的问题。
