Ceramsite concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses ceramsite concrete and a preparation method thereof. The ceramsite concrete comprises water, cement, ceramsite, fine aggregate, a mineral admixture, a polycarboxylate superplasticizer, dibromodimethyl hydantoin and sodium succinate sulfonate. The preparation method comprises the following steps: step 1), putting ceramsite into water, and performing standing for 12 hours to obtain a first prepared material; 2) mixing water, cement, a mineral admixture, fine aggregate, a TD-A polycarboxylate superplasticizer, dibromodimethyl hydantoin and sodium succinate sulfonate, and performing stirring for 24-36s at a rotating speed of 20-25r/min to form a second prepared material; and 3) mixing the second prepared material and the first prepared material, and performing stirring for 46-62 seconds at the rotating speed of 14-18 r/min to obtain the ceramsite concrete. By adopting the preparation method disclosed by the invention, the ceramsite concrete can be better homogenized to obtain better mechanical strength, and meanwhile, the production efficiency of a stirrer cannot be influenced.
本申请涉及混凝土领域，具体公开了一种陶粒混凝土及其制备方法。陶粒混凝土包括水、水泥、陶粒、细骨料、矿物掺合料、聚羧酸高效减水剂、二溴二甲基乙内酰脲、琥珀酸酯磺酸钠；其制备方法为：步骤1），将陶粒置于水中静止12小时获得第一预备料；步骤2），混合水、水泥、矿物掺合料、细骨料、TD‑A聚羧酸高效减水剂、二溴二甲基乙内酰脲、琥珀酸酯磺酸钠，转速20‑25r/min，搅拌24‑36s，形成第二预备料；步骤3），将第二预备料和第一预备料混合，转速14‑18r/min，搅拌46‑62s，获得陶粒混凝土。本申请的制备方法使得陶粒混凝土更好地均质获得更好的力学强度，同时又不会影响搅拌机的生产效率。
