Underwater concrete containing machine-made sand
The invention relates to the field of concrete, and particularly discloses underwater concrete containing machine-made sand and a preparation method of the underwater concrete. The underwater concrete containing the machine-made sand is characterized by being prepared from the following components: water, cement, fly ash, the machine-made sand, gravels and a water reducing agent, and the machine-made sand is prepared from the following components: orthoclase, calcite, fluorite, zircon, quartz, apatite, kaolinite, barite, an adhesive and a silane coupling agent. The preparation method comprises the following steps: 01) mixing cement and water to form cement slurry; 02) adding fly ash and a water reducing agent into the cement slurry, and uniformly mixing to form a mixed slurry; (03) adding machine-made sand and gravel into the mixed slurry, and uniformly mixing to form cement mortar, and (04) pouring the cement mortar into a mold, curing, and demolding to obtain the underwater concrete containing the machine-made sand. The underwater concrete containing the machine-made sand has the advantages that the application range is wide. In addition, the preparation method of the underwater concrete containing the machine-made sand has the advantage of being good in quality.
本申请涉及混凝土领域，具体公开了一种含机制砂的水下混凝土及其制备方法。含机制砂的水下混凝土，其特征在于：由包括以下组分制成：水、水泥、粉煤灰、机制砂、碎石、减水剂、机制砂由以下组分制成：正长石、方解石、萤石、锆石、石英、磷灰石、高岭石、重晶石、粘合剂、硅烷偶联剂。其制备方法为：步骤01），混合水泥和水，形成水泥浆液；步骤02），在水泥浆液中加入粉煤灰、减水剂，混合均匀，形成混合浆液；步骤03），在混合浆液中加入机制砂、碎石，混合均匀，形成水泥砂浆；步骤04），将水泥砂浆浇筑至模具中，养护，脱模，获得含机制砂的水下混凝土。其具有适用范围较广的优点；另外，本申请的制备方法具有质量较好优点。
