Retarded-setting and quick-hardening PVA fiber cement-based composite material as well as preparation method and application thereof
The invention relates to the technical field of building materials, in particular to a delayed-coagulation and rapid-hardening PVA fiber cement-based composite material as well as a preparation method and application thereof. Raw materials comprise 250 to 860 parts of a cement raw material, 380 to 1000 parts of an admixture, 400 to 580 parts of aggregate, 0.5 to 3.0 parts of dispersible latex powder, 10 to 40 parts of an early strength agent, 0.5 to 2 parts of a retarder, 0.2 to 3 parts of an alkali activator, 2 to 9 parts of a water reducing agent, 0.8 to 2.5 parts of a thickening agent, 1.5 to 7 parts of a defoaming agent, 6 to 26 parts of PVA fibers and 280 to 450 parts of water, and the total amount of the cement raw material and the admixture is 1200 to 1300 parts. According to the invention, the mixed slurry is firstly prepared and transported to a required position to prepare the PVA fiber cement-based composite material, initial setting is not generated, hardening within a short time can be realized, and the application requirements of various projects such as in-service foundation repair and reinforcement, municipal engineering, rapid airport repair and the like can be met.
本发明涉及建筑材料技术领域，具体涉及一种缓凝快硬的PVA纤维水泥基复合材料及制备方法和应用，以质量份计，原料包括250‑860份水泥原料、380‑1000份掺合料、400‑580份骨料、0.5‑3.0份可分散性乳胶粉、10‑40份早强剂、0.5‑2份缓凝剂、0.2‑3份碱激发剂、2‑9份减水剂、0.8‑2.5份增稠剂、1.5‑7份消泡剂、6‑26份PVA纤维，280‑450份水，水泥原料和掺合料共1200‑1300份。本发明先制备混合浆料，运输至所需位置后制得PVA纤维水泥基复合材料，既不产生初凝，又可短时间内硬化，可满足在役基础修补加固、市政工程、机场快速修补等各类工程的应用需求。
