Geopolymer-based rapid repair mortar and concrete and preparation method thereof
The invention relates to the technical field of building materials, in particular to geopolymer-based rapid repair mortar and concrete and a preparation method thereof. According to the geopolymer-based rapid repair mortar provided by the invention, the coal ash and the slag powder with a specific particle size range are used as powder materials, and the powder materials are jointly mixed with the fine aggregate, the exciting agent, the water reducing agent, the defoaming agent, the rubber powder and the water-retaining agent obtained by compounding different compounds to prepare the geopolymer-based rapid repair mortar. The geopolymer-based repair mortar not only has the advantages of fast setting and hardening, high early strength and excellent durability, but also has the advantages of low shrinkage rate, high bonding strength, high breaking strength and high compressive strength, so that the defects of easy shrinkage, easy cracking and easy falling of common geopolymer-based repair mortar are improved; the repairing agent can be used for quickly repairing cracks, broken plates, falling, dusting and other damages of buildings such as roads, airport runways and bridges.
本发明涉及建筑材料技术领域，具体涉及一种地聚物基快速修复砂浆、混凝土及其制备方法。本发明提供的地聚物基快速修复砂浆通过将具有特定粒径范围的粉煤灰和矿渣粉作为粉体料，并与细骨料、激发剂、减水剂、消泡剂、胶粉和由不同化合物复配得到的保水剂共同混合制备得到地聚物基快速修复砂浆。该地聚物基修复砂浆不仅具有快凝快硬、高早期强度和优良耐久性，同时还具有低收缩率、高粘结强度、高抗折强度和高抗压强度，进而使普通的地聚物基修复砂浆易收缩、易开裂及易脱落的缺点得到改善，可用于包括公路、机场跑道和桥梁等建筑出现的龟裂、断板、脱落、起砂等破损的快速修复。
