Anti-cracking concrete building block and its processing method
By incorporating specific functional materials and a pre-placed active interface layer into concrete blocks, combined with an interlocking structure, the cracking problem of concrete blocks during multi-stage shrinkage and deformation is solved, achieving volume stability and high-strength interfacial bonding throughout the entire life cycle of the blocks.

Abstract
本发明属于新型建筑材料及其制备技术领域，公开了一种防开裂混凝土建筑砌块及其加工方法。为解决现有混凝土砌块本体收缩开裂、砌块与砂浆界面变形不协调开裂的问题，本发明在砌块胶凝材料中内掺硫铝酸盐水泥熟料‑煅烧石膏、中活性轻烧氧化镁、超细矿渣粉‑硅灰三组功能材料，分阶段补偿混凝土各阶段收缩；在砌块砌筑面预置含高活性矿物掺合料的活性界面层及凹凸咬合构造，配套变形匹配的专用砂浆。本发明从材料层面同时解决砌块本体和界面开裂难题，适配现有砌块生产线，工艺简单，工业化落地性强，抗裂效果优异。
