The invention relates to a preparation method of a high-strength composite baking-free brick, and belongs to the technical field of building materials. The high-strength composite baking-free brick isprepared by adding gypsum whiskers and basalt short fibers, the gypsum whiskers are highly ordered in atomic structure arrangement during crystallization, the strength of the baking-free brick can beeffectively reinforced, and as the gypsum whiskers are fibrous crystals, impact energy can be absorbed, and the mechanical strength of the gypsum whiskers is high; crack propagation can be effectively inhibited in the cracking process of the baking-free brick, the fatigue resistance and the buffer resistance of the baking-free brick can be effectively improved, the strength of the baking-free brick can be remarkably improved through the basalt fibers, and the toughness and the impact fatigue resistance of the baking-free brick are well enhanced; a certain number of basalt short fibers are added into the baking-free brick, so that cracks of the baking-free brick can be prevented from appearing and expanding, the mechanical property of the baking-free brick can be effectively improved by doping the basalt fibers, and the tensile strength and the breaking strength of the baking-free brick are improved to different degrees.
本发明涉及一种高强度复合免烧砖的制备方法，属于建筑材料技术领域。本发明通过添加石膏晶须和玄武岩短纤维，制备一种高强度复合免烧砖，石膏晶须在结晶时原子结构排列高度有序，可以有效补强免烧砖的强度，由于石膏晶须的是纤维状晶体能吸收冲击能量，而且其机械强度大，在免烧砖破裂过程中能有效抑制裂纹扩展，可以有效提高免烧砖的抗疲劳性与抗缓冲性能，玄武岩纤维能够使免烧砖的强度得到显著的提高，同时对于免烧砖的韧性和抗冲击疲劳性能都有很好的改善，在免烧砖加入一定量的玄武岩短纤维可以预防免烧砖裂缝的出现和扩展，玄武岩纤维的掺入能有效的改善免烧砖的力学性能，使免烧砖的抗拉强度和抗折强度都得到不同程度的提高。
