Lightweight concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses lightweight concrete and a preparation method thereof. The lightweight concrete is prepared from the following raw materialsin parts by weight: cement, coarse aggregate, fine aggregate, water, a water reducing agent, basalt fibers, glass fibers, straw fibers, sodium alginate, calcium carbonate whiskers, D-mannitol, a foaming agent and a foam stabilizer. The preparation method comprises the following steps: S1, mixing and stirring the foaming agent and 35-40% of the total amount of water for 10-15 minutes to obtain a foaming solution; and S2, mixing and stirring all the rest raw materials and the rest water for 5-10 minutes, then adding the foaming solution obtained in the step S1, and continuing to stir for 20-30 minutes. The lightweight concrete has the advantages of good thermal insulation property, high mechanical property and long service life; in addition, the preparation method is simple in step, easy tooperate, low in cost of used raw materials and suitable for large-scale production.
本申请涉及混凝土领域，具体公开了一种轻质混凝土及其制备方法。轻质混凝土所用原料包括以下重量份的组分：水泥、粗骨料、细骨料、水、减水剂、玄武岩纤维、玻璃纤维、秸秆纤维、海藻酸钠、碳酸钙晶须、D‑甘露糖醇、发泡剂、稳泡剂；其制备方法为：S1.将发泡剂与水总量的35‑40%混合搅拌10‑15min，得到发泡溶液；S2.将其余所有原料与剩余的水混合搅拌5‑10min，然后加入步骤S1的发泡溶液，继续搅拌20‑30min。本申请的轻质混凝土具有保温性能好且力学性能高，使用寿命较长的优点；另外，本申请的制备方法步骤简单，易操作，使用的原料成本较低，适合大规模生产。
