Green high-performance concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses green high-performance concrete and a preparation method thereof. The green high-performance concrete is prepared from the following components: water, cement, fly ash, waste steel slag, aggregate, a water reducing agent, potassium alum and wood fiber. The preparation method comprises the following steps: 1) dissolving potassium alum in water to form a potassium alum solution, then adding wood fibers, continuously stirring and heating until the wood fibers are dried to obtain potassium alum modified wood fibers; 2) uniformly mixing the cement, the fly ash, the waste steel slag, the aggregate and the potassium alum modified wood fiber to obtain a premix, and 3) uniformly mixing the water and the water reducing agent, injecting the mixture into the premix, and uniformly mixing to obtain the green high-performance concrete.The green high-performance concrete has the advantages that the strength of the concrete is improved, and environmental pollution is reduced at the same time.
本发明涉及混凝土技术领域，具体公开了一种绿色高性能混凝土及其制备方法。一种绿色高性能混凝土，包括以下组分：水、水泥、粉煤灰、废钢渣、骨料、减水剂、钾明矾、木质纤维。制备方法包括：1），将钾明矾溶于水中，形成钾明矾溶液，然后投入木质纤维，持续搅拌并加热至烘干，得钾明矾改性木质纤维；2），将水泥、粉煤灰、废钢渣、骨料、钾明矾改性木质纤维混合均匀，得预混物；3），将水、减水剂混合均匀后注入预混物中，混合均匀，得绿色高性能混凝土。本发明具有提高混凝土强度的同时减少环境污染的优点。
