Composite concrete expansive agent based on industrial solid waste and preparation method of composite concrete expansive agent
The invention discloses a composite concrete expanding agent based on industrial solid waste and a preparation method thereof, the expanding agent is composed of 3000-3500 parts of expanding clinker, 2800-3500 parts of desulfurized gypsum, 4000-4500 parts of high-calcium fly ash, 20-40 parts of a gas forming component and 200-350 parts of a self-repairing component, the preparation method comprises the following steps: mixing and stirring the self-repairing component, the gas forming component and the high-calcium fly ash for 15 minutes to obtain a mixture A, mixing and stirring the expanding clinker and the desulfurized gypsum for 5 minutes to obtain a mixture B, and mixing and stirring the mixture A and the mixture B for 5 minutes to obtain the expanding agent. The preparation method is simple, the production cost is low, and the prepared expanding agent not only can compensate plastic expansion in concrete plastic stage shrinkage and prevent concrete plastic shrinkage cracking, but also has waterproof, permeation and crack self-repairing functions.
本发明公开了一种基于工业固废的复合型混凝土膨胀剂及其制备方法，膨胀剂由膨胀熟料3000‑3500份、脱硫石膏2800‑3500份、高钙粉煤灰4000‑4500份、发气组分20‑40份以及自修复组分200‑350份组成，其制备方法包括将自修复组分、发气组分以及高钙粉煤灰混合并搅拌15分钟，得到混合物A、将膨胀熟料和脱硫石膏混合并搅拌5分钟，得到混合物B、将混合物A和混合物B混合并搅拌5分钟，得到膨胀剂，本发明以高钙粉煤灰和脱硫石膏为主要原料，生产成本低，制备的膨胀剂不仅可以补偿混凝土塑性阶段收缩的塑性膨胀，防止混凝土塑性收缩开裂，而且还具有防水、渗透和裂缝自修复功能。
