Nucleating agent, copper tailing autoclaved aerated concrete product, preparation method and application
The invention relates to the technical field of building materials, and particularly discloses a nucleating agent, a copper tailing autoclaved aerated concrete product, a preparation method and application. The nucleating agent comprises the following raw materials: blast furnace slag, nano calcium carbonate, fly ash, acicular wollastonite powder, polycarboxylic acid, triterpenoid saponin and sodium silicate. The nucleating agent can be used for preparing autoclaved aerated concrete blocks by utilizing the characteristics of early enhancement and tobermorite crystallization induction, and by generating enough tobermorite to be inserted into CSH gel, the compressive strength is effectively improved, the shrinkage of the product is reduced, the dry density is low, and the problems that in the prior art, when copper tailings are used as raw materials for preparing autoclaved aerated concrete blocks, produced products are low in compressive strength, high in volume weight and large in shrinkage are solved. The provided preparation method is simple, can be used for rapidly and efficiently preparing the nucleating agent, and has a wide market prospect.
本发明涉及建筑材料技术领域，具体公开了一种晶核剂、铜尾矿蒸压加气混凝土制品、制备方法、应用，所述晶核剂包括以下的原料：高炉矿渣、纳米碳酸钙、粉煤灰、针状硅灰石粉、聚羧酸、三萜皂苷、泡花碱。本发明提供的晶核剂通过利用早期增强、诱导托贝莫来石结晶的特点，可以进行大掺量铜尾矿废渣来制备蒸压加气混凝土砌块，通过生成足够多的托贝莫来石穿插在CSH凝胶中，有效提高了抗压强度，并减少制品的收缩，干密度低，解决了现有技术中利用铜尾矿作为原料制备蒸压加气混凝土砌块时生产的产品存在抗压强度偏低、容重偏高、收缩偏大的问题；而提供的制备方法简单，可以快速高效地制备晶核剂，具有广阔的市场前景。
