Lightweight concrete and preparation method thereof
The invention relates to the field of concrete, in particular to lightweight concrete and a preparation method thereof. The lightweight concrete is prepared from, by mass, 350-500 parts of coarse aggregate; 200 to 280 parts of sand; 450 to 520 parts of cement; 60 to 120 parts of a hydrophobic organic resin-hollow glass bead composite system; 0.6 to 2.5 parts of a water reducing agent; 1-4 parts of a foaming agent; and 150 to 200 parts of water. The hydrophobic organic resin-hollow glass bead composite system is obtained by carrying out in-situ polymerization on at least one of a monovinyl aromatic monomer, a maleic acid monomer, an aliphatic olefin nitrile monomer and an aliphatic olefin carboxylic acid monomer on the surface of the hollow glass bead. According to the invention, the hydrophobic organic resin-hollow glass bead composite system is introduced, so that the impermeability of the concrete can be improved and the strength loss of the concrete can be reduced under the condition of ensuring light weight.
本申请涉及混凝土领域，具体涉及一种轻质混凝土及制备方法，其中轻质混凝土的原料包括如下质量份组分：粗骨料350～500份；砂200～280份；水泥450～520份；疏水有机树脂‑空心玻璃微珠复合体系60～120份；减水剂0.6～2.5份；发泡剂1～4份；水150～200份；疏水有机树脂‑空心玻璃微珠复合体系通过单乙烯基芳香单体、顺丁烯二酸类单体、脂肪族烯烃腈类单体和脂肪族烯烃羧酸类单体中的至少一种，在空心玻璃微珠表面发生原位聚合得到。在本申请中，通过引入疏水有机树脂‑空心玻璃微珠复合体系，可以在保证轻质的情况下，提高混凝土的抗渗性能，同时减少混凝土的强度损失。
