Lightweight building block and preparation method thereof
The invention provides a lightweight building block which comprises aggregate and a binder, and the binder comprises waste concrete recycled micro powder. The waste concrete recycled micro powder is particles with the particle size of 0.03 mm-0. 1 mm, which are obtained by screening waste concrete to remove coarse aggregate and fine aggregate and grinding the rest waste particles and powder. The preparation method comprises the following steps: mixing the waste concrete regenerated micro-powder, the alkaline calcium ion chelating agent, the soda-lime glass suspension dispersion liquid, the modified glass pumice and the silicon-aluminum mineral reinforcing agent according to a certain ratio, stirring, molding, sealing, and condensing and hardening in a drying oven at 60-90 DEG C to improvethe strength of the building block. According to the invention, the utilization of the waste concrete regenerated micro-powder is realized, the waste concrete micro-powder becomes a beneficial masonryadmixture after being treated, and under the premise of not doping cement, the regenerated micro-powder doped in a high proportion can form a gel with higher strength with other components so that the use of cement is reduced, and the environmental problem caused by the waste concrete micro-powder is also solved.
一种轻质砌块，包括骨料和粘结剂，所述粘结剂中包括废弃混凝土再生微粉。所述的废弃混凝土再生微粉为废弃混凝土筛选去除粗骨料和细骨料后，其余废弃的颗粒和粉体经粉磨后，获得的粒径介于0.03mm～0.1mm之间的颗粒。其制备方法是将废弃混凝土再生微粉、碱性钙离子螯合剂、钠钙玻璃悬浊分散液、改性玻璃轻石、硅铝质矿物增强剂按一定比例混合，搅拌成型，密封后在60‑90℃的烘箱内凝结硬化后形成以提高砌块强度。本发明实现了废弃混凝土再生微粉的利用，使废弃的混凝土微粉处理后成为一种有益的砌体掺合料，在不需要掺入水泥的前提下，高比例的掺入再生微粉能够与其他组分形成较高强度的胶凝物，不仅减少了水泥的使用，还解决了因废弃混凝土微粉造成的环境问题。
