Building gravel aggregate concrete and preparation method thereof
The invention discloses building gravel aggregate concrete and a preparation method thereof, and relates to the technical field of concrete. According to the scheme, building macadam, coal gangue and sand are used as aggregate, cement, modified steel fibers, fly ash, water, a water reducing agent and other components are added, epoxy resin mixed liquid is doped in the aggregate, the high-strength concrete is obtained, the dosage of all the components is limited, polymer coating modification is conducted on the coal gangue and the steel fibers, and the high-strength concrete is obtained. The finally obtained concrete has excellent compressive strength and breaking strength, and due to the existence of the epoxy resin mixed solution, the wear resistance and chloride ion corrosion resistance of the concrete are both improved.
本发明公开了一种建筑碎石骨料混凝土及其制备方法，涉及混凝土技术领域；方案利用建筑碎石以及煤矸石、砂子作为骨料，加入水泥、改性钢纤维、粉煤灰、水和减水剂等组分，并在其中掺杂环氧树脂混合液，得到高强度混凝土，方案对各组分用量进行限定，并对煤矸石、钢纤维进行聚合物包覆改性，最终得到的混凝土具有优异的抗压强度和抗折强度，且由于环氧树脂混合液的存在，混凝土的耐磨性能以及抗氯离子腐蚀性能均得到提升。
