Sandstone aggregate system concrete as well as preparation method and application thereof
The invention discloses sandstone aggregate system concrete as well as a preparation method and application thereof. The concrete is prepared from the following raw materials: cement, fly ash, mineral powder, sandstone broken stone with a first particle size, sandstone broken stone with a second particle size, sandstone broken stone with a third particle size, sandstone machine-made sand and sandstone chip powder. The particle size of the sandstone gravel with the first particle size is 5-9.5 mm; the particle size of the sandstone gravel with the second particle size is 10-19.5 mm; the particle size of the sandstone gravel with the third particle size is 20-31.5 mm. By preparing the sandstone aggregate system high-strength high-performance concrete, comprehensive utilization of sandstone aggregate broken stone, machine-made sand and stone chip powder is realized, the later strength and durability of the sandstone aggregate are further improved under the condition of guaranteeing the working performance of the concrete, and the application of the sandstone aggregate in the field of high-strength high-performance concrete is expanded.
本发明公开了一种砂岩骨料体系混凝土及其制备方法与应用，该混凝土包括以下制备原料：水泥、粉煤灰、矿粉、第一粒径砂岩碎石、第二粒径砂岩碎石、第三粒径砂岩碎石、砂岩机制砂和砂岩石屑粉；所述第一粒径砂岩碎石的粒径为5mm～9.5mm；所述第二粒径砂岩碎石的粒径为10mm～19.5mm；所述第三粒径砂岩碎石的粒径为20mm～31.5mm。本发明通过制备砂岩骨料体系高强高性能混凝土，实现了对砂岩骨料碎石、机制砂和石屑粉的综合利用，在保障混凝土工作性能的条件下，进一步提高了其后期强度与耐久性能，拓展了砂岩骨料在高强高性能混凝土领域的应用。
