摘要

叶蜡石主要用于陶瓷工业，因为它具有高耐火度。叶蜡石因其热转化为莫来石，在高温下稳定，是一种适用于耐火非定型材料和各种陶瓷定型制品的矿物添加剂。在本研究中，叶蜡石被用作陶瓷中50%的粘土替代品和砂浆中高达30%的水泥替代品。对其物理力学性能进行了研究。在1200℃下处理的陶瓷的烧成收缩?叶蜡石的加入使C还原。叶蜡石在水泥水化过程中起额外的火山灰作用。在微观结构内，形成结晶叶叶状的微增强物，提高了普通硅酸盐水泥、高铝酸盐水泥和混合水泥砂浆的力学性能。研究证明了叶蜡石在陶瓷中替代粘土和砂浆中替代水泥的有效性和适用性。

Application of pyrophyllite in high-temperature treated building materials

Phyllosilicate mineral pyrophyllite is predominantly used in the ceramic industry because it exhibits high refractoriness. Due to its thermal transformation into mullite, pyrophyllite is stable at elevated temperatures, making it a suitable mineral additive for refractory non-shaped materials and various ceramic shaped products. In this study, pyrophyllite is employed as 50 % clay replacement in the ceramics and up to 30 % cement replacement in mortars. Physico-mechanical properties were investigated. The firing shrinkage in the ceramics treated at 1200?C was reduced by pyrophyllite addition. Pyrophyllite acted as additional pozzolana during cement hydration. Within the microstructure, it formed micro-reinforcement in the shape of crystalline folia, which improves the mechanical properties of ordinary Portland cement, high aluminate cement, and blended cement mortars. The investigation proved the efficiency and suitability of pyrophyllite employed as a substitution for clay in ceramics and a cement replacement in mortars.
