Cold-proof anti-cracking low-temperature concrete formula
The invention discloses a cold-proof anti-cracking low-temperature concrete formula, and aims to solve the problem that traditional concrete is prone to freeze-thaw damage and crack propagation in a low-temperature environment. The formula comprises cement, fine aggregate, coarse aggregate, an anti-freezing agent, an anti-cracking agent and water, and the concrete is ensured to have good freezing resistance and cracking resistance in a low-temperature environment of-10 DEG C to 5 DEG C through a specific ratio and a specific preparation process. The preparation method comprises the steps of material preparation, dry material mixing, antifreezing agent and anti-cracking agent adding, water adding and stirring, concrete quality inspection, pouring, curing and the like. By implementing the invention, the performance of the concrete in a low-temperature environment can be remarkably improved, the service life of a project is prolonged, and the concrete is suitable for concrete projects such as building structures, roads, bridges, tunnels and water conservancy projects.
本发明公开了一种防寒抗裂低温砼配方，旨在解决传统混凝土在低温环境下易发生冻融破坏和裂缝扩展的问题。该配方包括水泥、细骨料、粗骨料、防冻剂、抗裂剂和水，通过特定的配比和制备工艺，确保混凝土在‑10℃至5℃的低温环境下具有良好的抗冻性和抗裂性。本发明的制备方法包括材料准备、干料混合、添加防冻剂和抗裂剂、加水搅拌、混凝土质量检查、浇筑和养护等步骤。通过实施本发明，可以显著提高混凝土在低温环境下的性能，延长工程的使用寿命，适用于建筑结构、道路、桥梁、隧道、水利工程等混凝土工程。
