Expansion fiber anti-crack waterproof concrete and preparation method thereof
The invention relates to expansive fiber anti-crack waterproof concrete, which is prepared from the following components in parts by mass: 880 to 950 parts of sand, 970 to 1020 parts of gravel, 45 to 55 parts of fly ash, 280 to 320 parts of cement, 150 to 170 parts of water, 30 to 40 parts of stone powder, 35 to 50 parts of expansive fiber and 6.6 to 7.8 parts of additives. The preparation method comprises the following steps: pouring 970-1020 parts of broken stone, 880-950 parts of sand, 45-55 parts of fly ash and 280-320 parts of cement into a concrete mixer, uniformly mixing, adding 30-40 parts of stone powder and 35-50 parts of expansion fiber, continuously uniformly mixing, uniformly mixing 6.6-7.8 parts of admixture and 150-170 parts of water, adding into the mixer, and continuously uniformly mixing to obtain the concrete mixture. The concrete is good in impermeability and early-stage crack resistance, and is suitable for underground engineering, large-scale pools and other concrete engineering with high waterproof requirements.
本发明涉及一种膨胀纤维抗裂防水混凝土，按质量份计，包括880～950份砂、970～1020份碎石、45～55份粉煤灰、280～320份水泥、150～170份水、30～40份石粉、35～50份膨胀纤维、6.6～7.8份外加剂。其制备方法是：将970～1020份碎石、880～950份砂、45～55份粉煤灰、280～320份水泥倒入混凝土搅拌机搅拌均匀，再加入30～40份石粉和35～50份膨胀纤维继续搅拌均匀，最后将6.6～7.8份外加剂与150～170份水均匀混合，加入到搅拌机内继续搅拌均匀，得到混凝土拌合物。本发明抗渗性、早期抗裂性好，适用于地下工程、大型水池等防水性要求较高的混凝土工程。
