The invention discloses an environment-friendly high-toughness hollow brick and a preparation method thereof. The method comprises the following steps: weighing and pretreating raw materials; stirring to prepare mixed slurry; preparing a hollow brick mud blank; the shale is used as a main material, the waste material, the straw powder and the composite cement are used as auxiliary materials, and the early strength agent and the concrete accompanying fiber are added, so that compared with existing hollow brick preparation raw materials, the raw material cost is reduced, waste utilization is realized, the hollow brick is more environment-friendly, and the selected materials are beneficial to improving the strength, toughness, heat preservation, noise reduction and other properties of the hollow brick; in the preparation process, the drying performance of the raw materials is improved, the water content is guaranteed, pug particles are closely drawn close and connected through the vacuum degassing technology, forming is easy, the toughness and strength are further improved, finally, slow temperature rising in the roasting process is controlled, the toughness and strength of the hollow brick are prevented from being damaged, and the hollow brick is not prone to cracking; and the anti-seismic property is good.
本发明公开一种环保高韧性空心砖及其制备方法，其方法包括以下步骤：原料称量预处理、搅拌制备混合浆料、制备空心砖泥胚料以及空心砖焙烧成型；本发明以页岩为主料，以废弃料、秸秆粉料和复合水泥为辅料，并加入早强剂和砼伴纤维，相比现有的空心砖制备原料，不仅降低了原料成本，还实现了废物利用，更为环保，且选料还有助于提升空心砖的强度、韧性和保温降噪等性能，且制备过程中改善了原料的干燥性能，保证了含水率，真空除气的工艺使泥料颗粒紧密靠拢联接，易于成型并进一步增加韧性和强度，最后通过控制焙烧过程中缓慢升温，避免破坏空心砖的韧性和强度，使空心砖不易开裂，具备良好的抗震性能。
