High-strength ultramicro admixture for sprayed concrete, preparation method and use method of high-strength ultramicro admixture, low-rebound-rate sprayed concrete and preparation method of low-rebound-rate sprayed concrete
The invention provides a high-strength ultramicro admixture for sprayed concrete, a preparation method and a use method of the high-strength ultramicro admixture, low-rebound-rate sprayed concrete and a preparation method of the low-rebound-rate sprayed concrete, and relates to the technical field of building materials. The high-strength ultramicro admixture for sprayed concrete is prepared from the following components: superfine silicon dioxide, ground slag powder, optional aluminum sulfate, optional calcium sulfate, calcium hydroxide, sodium hydroxide, polyacrylamide, optional hydroxypropyl methyl cellulose and polyvinyl alcohol. The technical problems that common sprayed concrete is high in rebound rate, large in dust rate and low in strength are solved, and the technical effects that the rebound rate and the dust capacity of the sprayed concrete are effectively reduced, and meanwhile the strength and durability of the sprayed concrete are improved are achieved.
本发明提供了一种喷射混凝土用高强超微外加剂及其制备方法、使用方法、低回弹率喷射混凝土及其制备方法，涉及建筑材料的技术领域，本发明的喷射混凝土用高强超微外加剂包括以下组分：超细二氧化硅、磨细矿渣粉、任选的硫酸铝、任选的硫酸钙、氢氧化钙、氢氧化钠、聚丙烯酰胺、任选的羟丙基甲基纤维素，以及聚乙烯醇。本发明解决了普通喷射混凝土回弹率高、粉尘率大以及强度低的技术问题，达到了有效降低喷射混凝土回弹率和粉尘量，同时提高喷射混凝土强度和耐久性的技术效果。
