Metamorphic rock aggregate high-strength concrete and preparation method thereof
The invention relates to metamorphic rock aggregate high-strength concrete and a preparation method thereof, and the concrete is prepared from the following components: cement, an early-strength auxiliary cementing material, an easy-flowing auxiliary cementing material, metamorphic rock machine-made sand, metamorphic rock broken stone, water, an efficient composite admixture and an AZK auxiliary agent in a mass ratio of (310-350): (50-75): (135-150): (786-896): (896-960): (156-161): (7.3-8.6): (2.1-3.1). The alkali aggregate reaction of the metamorphic rock is effectively inhibited by synergistic use of a series of technologies, and high fluidization and high reinforcement of the concrete prepared from the metamorphic rock aggregate are realized. And a basis is provided for mass use of metamorphic rocks in engineering.
本发明涉及一种变质岩骨料高强混凝土及其制备方法，混凝土各组分质量比如下：水泥：早强型辅助胶凝材料：易流型辅助胶凝材料：变质岩机制砂：变质岩碎石：水：高效复合外加剂：AZK辅助剂＝310～350：50～75：135～150：786～896：896～960：156～161：7.3～8.6：2.1～3.1，本发明通过系列技术的协同使用，有效抑制变质岩的碱骨料反应，实现变质岩骨料制备混凝土的高流态化、高强化。为变质岩在工程中的大体量使用提供依据。
