摘 要

水泥是重要的建筑材料，但是随着社会的快速发展，水泥工业面临的问题却越来越多，对其性能的要求也越来越高。提高传统硅酸盐水泥的性能，满足现代建筑工程对水泥材料的多功能、高性能的要求，并达到节约资源、能源、保护环境的目的，实现水泥工业的可持续发展，对国民经济与社会发展具有重要意义。

当前，我国是水泥生产大国，我们都知道，水泥的生产需要消耗很多的能源；毫无疑问，这样的情况使我们处于非常不利的地位，尤其在这样资源非常紧缺的年代。近些年，资源消耗、环境污染、人口增多等众多问题日益加剧，其中环境污染问题，对于我们水泥行业相关研究者来说责任重大。水泥生产制造过程能耗较高、污染严重，围绕水泥生产制造及其应用过程的各个环节，开展节能减排和改善水泥性能的实验研究，具有深远意义。当能源消耗和环境保护益发冲突之时，低能耗水泥制备及高效应用水泥新技术的研究受到众多水泥行业工作者的亲睐。而硫铝酸盐水泥因为其具有早期水化快、强度高及后期强度较高等许多优越性能，使之成为许多人研究的重点。硫铝酸钙（Ye’elimite，3CaO·3Al₂O₃·CaSO₄，缩写为C₄A₃$）、铝酸三钙、铁铝酸四钙是硫铝酸盐水泥中的重要矿物相，他们对硫铝酸盐水泥性能的影响很大。当前对硫铝酸钙水泥中各矿物相形成情况已有大量的研究，硫铝酸钙在铁相以及铝酸三钙存在下的形成情况的研究相对较少，为了充分利用硫铝酸盐水泥的众多优点，本文将重点研究CaO-Al₂O₃-Fe₂O₃-SO₃体系矿物形成，通过相应的理论配比，设计C₄AF、C₄A₃$等矿相原料的含量，使用纯的化学原料，根据不同烧成温度以及保温的时间来确定理论配比，确定体系的矿相组成，最后测试相应单矿的性能。

Study on the mineral formation and hydration of CaO-Al₂O₃-Fe₂O₃-SO₃ system

ABSTRACT

Cement is still one of the fundamental materials which are widely and largely used in civil engineering. With the development of society, the cement industry has faced to more and more problems. How to improve the performances of cement, to save energy sources and resource, to protect environment, is a main direction science and technology of cement. It will take on important significance for economy and social development.

Currently, Our country's cement output is very high ; As we all know, cement production needs to consume a lot of energy, There is no doubt that the situation put us at a serious disadvantage especially In such times of shortage of resource. In recent years, resource consumption, environmental pollution, population increase and many other problems have become increasingly severe , Our cement-related researchers have a great responsibility on the problems environmental pollution. Cement manufacturing process need to consume a lot of energy and cause serious environmental pollution. It is significant to concentrate on the cement production and application for each link of the process of energy conservation, emissions reduction and improve the basic research of the cement performance. Alite-sulfoaluminate cement combines the advantage of alite and calcium sulfoaluminate, while has a good performance in application.

Calcium sulfoaluminate (Ye’elimite,3CaO·3Al₂O₃·CaSO₄,abbreviation for C₄A₃$),  tricalcium aluminate, tetracalcium aluminoferrite as the important mineral phase in sulfoaluminate cement,has an enormous influence in cement performances. So far, there has been little attention on the kinetics of calcium sulfoaluminate formation along with iron and aluminate phases. In order to make full use of the many advantages of sulphur aluminate cement, This research focuses on the mineral formation of the CaO-Al₂O₃-Fe₂O₃-SO₃ system, Through the ratio of the corresponding theory, design the content of mineral raw materials: C₄AF and C₄A₃$; the experiment will use the pure chemical raw materials; In addition, according to the different sintering temperature and heat preservation time to determine the ratio of theory. Determine the mineral phase composition of system, the final test performance of the corresponding single ore.

Key words : calcium sulfoaluminate; tetracalcium aluminoferri; the CaO-Al₂O₃-Fe₂O₃-SO₃ system
