Lightweight high-strength anti-cracking self-repairing tuff concrete and preparation method thereof
The invention relates to the technical field of concrete materials, and particularly discloses light high-strength anti-cracking self-repairing tuff concrete and a preparation method thereof. The lightweight high-strength anti-cracking self-repairing tuff concrete is mainly prepared from the following raw materials: a component A: tuff powder, cationic polyacrylamide and water; the component B comprises cement, silica fume, ceramsite, a water reducing agent, an air entraining agent, an anti-crack repairing agent, quick lime and water; the preparation method of the light high-strength anti-cracking self-repairing tuff concrete comprises the following steps: (1) component A mixing: uniformly mixing cationic polyacrylamide, water and tuff powder to obtain a mixture A; (2) mixing the component B: uniformly mixing the raw materials of the component B to obtain a mixture B; and (3) concrete preparation: uniformly mixing the mixture A and the mixture B to obtain the concrete. The tuff concrete prepared by the invention has a relatively good self-repairing effect when being cracked.
本申请涉及混凝土材料技术领域，具体公开了一种轻质高强抗开裂自修复凝灰岩混凝土及其制备方法。本申请的轻质高强抗开裂自修复凝灰岩混凝土，主要由如下原料制成，A组分：凝灰岩粉、阳离子聚丙烯酰胺、水；B组分：水泥、硅灰、陶粒、减水剂、引气剂、抗裂修复剂、生石灰、水；本申请的轻质高强抗开裂自修复凝灰岩混凝土的制备方法，包括如下步骤：（1）A组分混合：将阳离子聚丙烯酰胺、水、凝灰岩粉混合均匀，即得混合物A；（2）B组分混合：将B组分的原料混合均匀，即得混合物B；（3）混凝土制备：将混合物A与混合物B混合均匀，即得。本申请制得的凝灰岩混凝土开裂时的自修复效果较佳。
