High-strength, impermeable and frost-resistant concrete and processing technology thereof
The invention relates to the technical field of concretes, and discloses a high-strength, impermeable and frost-resistant concrete and a processing technology thereof. The high-strength, impermeable and frost-resistant concrete is prepared from, by weight, 270 to 300 parts of cement, 70 to 80 parts of mineral powder, 45 to 55 parts of fly ash, 650 to 850 parts of medium sands, 860 to 1260 parts ofgravels, 4 to 5 parts of additives and 135 to 175 parts of water. Proper aggregates and excellent proportions are adopted, and a reasonable construction process is matched, so that the concrete has the advantages of high strength, frost resistance and impermeability after being poured, large-volume concrete such as ship locks, dams and the like can be prevented from generating cracks, the durability and the bearing capacity of concrete components are improved, and the service life is prolonged.
本发明涉及混凝土技术领域，且公开了一种高强抗渗抗冻混凝土及其加工工艺，所述高强抗渗抗冻混凝土由以下份量原料组成：水泥270‑300份，矿粉70‑80份，粉煤灰45‑55份，中砂650‑850份，碎石860‑1260份，外加剂4‑5份，水135‑175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、抗冻和抗渗的优点，能够防止船闸和大坝等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，从而提高使用寿命。
