Cement-free baking-free prefabricated brick blank film based on clay building residue soil and preparation method of cement-free baking-free prefabricated brick blank film
The invention provides a clay building residue soil-based cement-free baking-free prefabricated brick blank membrane, which is prepared from the following components in parts by weight: 20 to 30 parts of ground calcined clay soil, 50 to 60 parts of crushed calcined clay soil, 10 to 15 parts of quick lime, 3 to 5 parts of gypsum, 2 to 3 parts of activating agent, 1 to 2 parts of dispersing agent and 10 to 20 parts of water, the levigated and crushed calcined clayey soil is prepared by the following method: calcining clay building residue soil at low temperature to activate the gelling performance of the clay building residue soil to obtain calcined clayey soil, grinding a part of the calcined clayey soil, screening calcined clayey soil powder with the particle size of less than 200 meshes as levigated calcined clayey soil, and crushing the levigated and crushed calcined clayey soil to obtain the levigated and crushed calcined clayey soil. And crushing the residual ground product and the residual calcined clay to be less than 3mm to obtain the crushed calcined clay. Related preparation methods are also provided. The prefabricated brick blank film can be produced by utilizing clay building muck generated by excavation of a foundation pit, so that the production cost is reduced, and carbon emission is reduced.
本发明提供一种基于黏土质建筑渣土的无水泥免烧预制砖胎膜，包括：磨细煅烧黏质土20～30重量份、粉碎煅烧黏质土50～60重量份、生石灰10～15重量份、石膏3～5重量份、活化剂2～3重量份、分散剂1～2重量份和水10～20重量份，其中，磨细和粉碎煅烧黏质土通过以下方法制备：将黏土质建筑渣土通过低温煅烧激活其胶凝性能，得到煅烧黏质土，将一部分煅烧黏质土研磨后筛取粒径小于200目的煅烧黏质土粉末作为磨细煅烧黏质土，将筛余的研磨产物和剩余的煅烧黏质土粉碎至3mm以下，得到粉碎煅烧黏质土。还提供相关制备方法。本发明的预制砖胎膜能够利用基坑开挖产生的黏土质建筑渣土进行生产，从而降低生产成本，降低碳排放。
