Raft foundation mass concrete and preparation method thereof
The invention relates to the field of mass concrete, and particularly discloses raft foundation mass concrete and a preparation method thereof, and the mass concrete comprises the following raw materials by weight: 120-140 parts of cement; 30 to 70 parts of fly ash; 20-30 parts of slag powder; 490 to 590 parts of broken stone; 340 to 370 parts of machine-made sand; 0.6 to 0.8 part of a water reducing agent; 70 to 90 parts of mixing water; 1.9 to 2.1 parts of tannic acid; 10 to 20 parts of an anti-crack filling material; the anti-crack filler comprises the following raw materials in parts by weight: 20 parts of yarn cut-off material; 2-10 parts of an expanding agent; and 0.3 to 0.7 part of lubricating powder. The preparation method comprises the following steps: S1, taking the gravels and the machine-made sand as aggregates; s2, uniformly stirring cement, fly ash, slag powder, a water reducing agent, aggregate, mixing water, tannic acid and an anti-cracking filler to obtain an admixture; and S3, pouring the admixture on the raft, and curing to obtain the product. The method has the effect of improving the anti-cracking capability of the mass concrete.
本申请涉及大体积混凝土领域，具体公开了一种筏板基础大体积混凝土及其制备方法，大体积混凝土包括以下重量份的原料：水泥120～140份；粉煤灰30～70份；矿渣粉20～30份；碎石490～590份；机制砂340～370份；减水剂0.6～0.8份；拌合水70～90份；单宁酸1.9～2.1份；抗裂填料10～20份；抗裂填料包括以下重量份的原料：纱线切断料20份；膨胀剂2～10份；润滑粉0.3～0.7份。其制备方法为：S1、碎石和机制砂作为集料；S2、水泥、粉煤灰、矿渣粉、减水剂、集料、拌合水、单宁酸和抗裂填料搅拌均匀得到掺合料；S3、掺合料浇筑在筏板上，养护后即得。本申请具有提高大体积混凝土抗开裂能力的效果。
