Method for producing high-performance concrete by utilizing industrial waste residues
The invention discloses a method for producing high-performance concrete by utilizing industrial waste residues in the technical field of industrial waste residue production and utilization, which is characterized in that polymer fibers are added into the high-performance concrete produced by utilizing waste slag, so that microcracks of the concrete caused by factors such as solid plastic shrinkage, air shrinkage, temperature change and the like are effectively controlled; in addition, the water reducing agent is added, the slump of the concrete can be maintained, the mixing water consumption can be reduced, and the polymer rubber powder can increase the matching degree of all the components, so that compared with common foamed concrete, the concrete has better strength, and the natural protein foaming agent prepared from cottonseed protein is added, and therefore, the concrete has better foaming performance, and the cost of construction materials is reduced.
本发明公开了工业废渣生产利用技术领域的一种利用工业废渣生产高性能混凝土的方法，本发明利用废矿渣生产的高性能混凝土中添加了聚合物纤维，有效控制混凝土因固塑性收缩、干缩、温度变化等因素产生微裂缝，大大改善混凝土的阻裂抗渗性能，另外还添加了减水剂，可以维持混凝土坍落度和减少拌合用水量，聚合物胶粉可以增加各组分的配合度，所以与普通发泡混凝土相比用于较好的强度，并且添加了利用棉籽蛋白制备的天然蛋白发泡剂，使该混凝土拥有更好的发泡性能，降低建设用料成本。
