High-strength concrete and construction process thereof
The invention relates to the technical field of concrete construction, and discloses high-strength concrete, which is prepared from the following raw materials in parts by weight: 90 to 110 parts of cement, 4 to 6 parts of fly ash, 2.4 to 2.8 parts of additive, 25 to 30 parts of water, 115 to 135 parts of sand, 233 to 253 parts of broken stone and 20 to 30 parts of mineral powder. According to theinvention, proper aggregate and an excellent proportion are adopted, and a reasonable construction process is matched, so that the concrete has the advantages of high strength and high resistance after being poured, cracks generated by mass concrete can be reduced, the durability and the bearing capacity of a concrete member are improved, the service life is prolonged, and the use safety of a concrete building is improved.
本发明涉及混凝土施工技术领域，且公开了一种高强型混凝土，所述的高强型混凝土由以下份量原料组成：水泥90‑110份，粉煤灰4‑6份，外加剂2.4‑2.8份，水25‑30份，砂115‑135份，碎石233‑253份，矿粉20‑30份。本发明采用合适的骨料和优良的配比，配合合理的施工工艺，使得混凝土在浇筑后，具备高强度、高抗性的优点，能够减少大体积混凝土产生裂缝，有利于提高混凝土构件的耐久性和承载力，提高使用寿命，从而提高混凝土建筑的使用安全性。
