Early-strength shrinkage-free grouting material and preparation method thereof
The invention relates to the technical field of buildings, in particular to an early-strength shrinkage-free grouting material and a preparation method thereof.The early-strength shrinkage-free grouting material is prepared from, by weight, 25%-30% of quick-hardening cement, 5%-8% of fine early-strength cement, 40%-50% of gravel, 5%-10% of water and 5%-10% of quick-hardening auxiliaries, and the quick-hardening auxiliaries are added into the early-strength shrinkage-free grouting material. The proportion of the water is 15%-20%, the proportion of the rapid hardening auxiliary agent is 5%-9%, and the rapid hardening auxiliary agent is prepared by mixing a water reducing agent, a defoaming agent, an early strength agent and a flocculating agent. According to the early-strength shrinkage-free grouting material and the preparation method thereof, the formula ratio of the grouting material and the used raw materials are changed, the early-strength cement and the quick-hardening cement are used in the aspect of cement, so that the grouting material has high hardening speed so as to meet the construction requirement, meanwhile, the quick-hardening additive is added, and the proportion of all components of the additive is changed, so that the early-strength shrinkage-free grouting material is prepared. The grouting material meets the construction requirements, and the hardening time is short.
本发明涉及建筑技术领域，具体为一种早强型无收缩灌浆料及其制备方法，包括以下重量份数配比的原料：快硬水泥、精细早强型水泥、砂石、水以及快硬助剂，所述水泥的占比为：25％～30％，所述精细早强型水泥的占比为：5％～8％，所述砂石的占比为：40％～50％，所述水的占比为：15％～20％，所述快硬助剂的占比为：5％～9％，所述快硬助剂由减水剂、消泡剂、早强剂以及絮凝剂混合制成。该早强型无收缩灌浆料及其制备方法，过改变灌浆料的配方比及其所使用的原材料，在水泥方面，使用早强型水泥以及快硬水泥，使得灌浆料具有较快的硬化，以满足施工需求，同时添加快硬助剂，改变添加剂的各组分比例，使得灌浆料符合施工需求，获得较快的硬化时间。
