Machine-made sand concrete and preparation process thereof
The invention relates to the technical field of concrete preparation, and discloses machine-made sand concrete and a preparation process thereof.The machine-made sand concrete comprises broken stone, machine-made sand, cement and water according to a conventional ratio, the cement is slag cement, and the slag cement comprises, by weight, 20-25 parts of steel slag, 18-32 parts of blast furnace slag, 2-4 parts of water, 1-3 parts of a water reducing agent, 1-3 parts of a water reducing agent and 1-3 parts of a water reducing agent. And 6-12 parts of Portland cement clinker. The prepared machine-made sand concrete is good in anti-permeability and anti-carbonization capacity, the chemical corrosion resistance and bonding strength of the machine-made sand concrete are improved through the added barium sulfide industrial waste residues, and the machine-made sand concrete has the long service life. The invention solves the industrial technical problems in preparation of green high-performance concrete from machine-made sand and industrial waste residues, and breaks through the common key technical problems of high-efficiency production regulation and control of machine-made sand and the like.
本发明涉及混凝土制备技术领域，且公开了一种机制砂混凝土及其制备工艺，该机制砂混凝土包括常规配比的碎石、机制砂、水泥及水，所述水泥为矿渣水泥，按重量份计，该矿渣水泥的原料组成包括：钢渣20‑25份，高炉矿渣18‑32份，硅酸盐水泥熟料6‑12份。本发明所制得的机制砂混凝土抗渗性、抗碳化能力较佳，添加的硫化钡工业废渣提升了机制砂混凝土的耐化学腐蚀性和结合强度，使机制砂混凝土具有较长的使用寿命。本发明解决了机制砂与工业废渣制备绿色高性能混凝土面临的行业技术难题，突破了机制砂高效生产调控等共性关键技术难题。
