Lightweight aggregate concrete and preparation method thereof
The invention relates to concrete, in particular to lightweight aggregate concrete and a preparation method thereof. The concrete comprises the following components in parts by weight: 98 parts of cement, 66 parts of fly ash, 87 parts of micro-absorbent ceramsite, 238 parts of fine aggregate, 3.2 parts of a water reducing agent, 3.2 parts of a synergist, 2.6 parts of sodium monofluorophosphate, 3.1 parts of sodium alginate, 74 parts of water, 20 parts of ulothrix and 20 parts of glass fibers. According to the invention, micropores of the ceramsite are sealed by light and waterproof starch slurry, so the ceramsite is not easy to absorb water during subsequent stirring with water, the strength of the ceramsite is improved, and finally, the effect of improving the strength of concrete is achieved; and ulothrix is uniformly distributed in the concrete, which is equivalent to the construction of a flexible limiting net, so each ceramsite is difficult to escape from the original position through buoyancy.
本发明涉及混凝土，尤其是一种轻集料混凝土及其制备方法；它包括以下重量份数的组分：水泥98份、粉煤灰66份、微吸水陶粒87份、细骨料238份、减水剂3.2份、增效剂3.2份、单氟磷酸钠2.6份、海藻酸钠3.1份、水74份、丝藻20份和玻纤20份。首先通过轻质且防水的防水淀粉浆液封闭陶粒的微孔，使得陶粒后续与水的搅拌中不容易吸水，从而提高陶粒本身的强度，最终达到提升混凝土强度的效果；还通过丝藻均匀分布在混凝土中，相当于构建一个柔韧的限位网，使得各个陶粒比较难通过浮力逃离原位置。
