Fly ash-doped concrete capable of improving performance and reducing hydration heat and preparation method thereof
The invention relates to the field of concrete, and particularly discloses fly ash-doped concrete capable of improving performance and reducing hydration heat and a preparation method thereof. The fly ash-doped concrete comprises the following components in parts by mass: 240-250 parts of cement; 800-850 parts of sand; 1050-1100 parts of stone; 150-170 parts of water; 50-60 parts of fly ash; 5-8 parts of a water reducing agent; 3-8 parts of zinc chromate; 1-3 parts of starch; the preparation method comprises the following steps: uniformly stirring and mixing the components, and curing and molding to obtain the fly ash-doped concrete capable of improving the performance and reducing the hydration heat. The product disclosed by the invention can be applied to various building constructions, and has the advantage that the bleeding rate and the early strength are not easily influenced.
本申请涉及混凝土领域，具体公开了一种掺粉煤灰改善性能和降低水化热的混凝土及其制备方法。掺粉煤灰改善性能和降低水化热的混凝土包括以下质量份数的组分：水泥240‑250份；砂800‑850份；石1050‑1100份；水150‑170份；粉煤灰50‑60份；减水剂5‑8份；铬酸锌3‑8份；淀粉1‑3份；其制备方法包括以下步骤：将各组分搅拌混合均匀，再经养护成型，即得掺粉煤灰改善性能和降低水化热的混凝土。本申请的产品可用于各种建筑施工中，其具有泌水率以及早期强度不容易受到影响的优点。
