Solid waste-based composite curing agent and preparation method thereof
The invention discloses a geopolymer curing agent with high mechanical property and a preparation method thereof, the geopolymer curing agent is prepared from the following raw materials in parts by weight: 10-60 parts of fly ash, 10-50 parts of cement, 5-40 parts of lime, 10-30 parts of modified zeolite, 1-60 parts of modified sepiolite, 5-30 parts of modified cellulose nanometre, 1-35 parts of porous silicon and 1-15 parts of synergist. The water-binder ratio is 0.40. The modified cellulose nanofibers are dispersed in a matrix through high strength and high toughness of the modified cellulose nanofibers, so that formation and expansion of cracks are effectively prevented, and the crack resistance of the curing agent is improved; due to the high porosity and surface area of the porous silicon, the compactness and strength of the curing agent are enhanced, and damage to the surface of the curing agent by abrasive is reduced; the use of the synergist ensures the uniform distribution of each component of the curing agent in the curing process, and ensures the good construction performance and final mechanical properties of the curing agent, so that the composite curing agent shows excellent wear resistance and durability in engineering application.
本发明公开了一种高力学性能的地聚物固化剂及其制备方法，原料包括如下重量份的原料：粉煤灰10‑60份、水泥10‑50份、石灰5‑40份、改性沸石10‑30份、改性海泡石1‑60、改性纤维素纳米5‑30份、多孔硅1‑35份、增效剂1‑15份，复合固化剂利用减水剂调节水胶比，其水胶比为0.40。本申请的改性纤维素纳米纤维通过其高强度和高韧性，分散在基体中有效阻止裂纹的形成和扩展，提高了固化剂的抗裂性能；多孔硅的高孔隙率和表面积，增强了固化剂的密实度和强度，减少了磨料对固化剂表面的破坏；增效剂的使用确保了固化剂在固化过程中各成分的均匀分布，保证了固化剂的良好施工性能和最终的力学性能，使得该复合固化剂在工程应用中表现出优异的耐磨性和持久性。
