摘要随着我国经济的快速发展，我国的城市化进程的不断开展以及废旧道路、房屋等的翻修与拆迁，越来越多的固体废弃物不能得到有效地及时的处理，固体废弃物的随意丢弃、摆放和掩埋对我国的环境和人们的生活质量产生了巨大的影响。同时，由于大量建筑的建造，我国资源正在被快速的消耗，更加加剧了环境的恶化。因此，如何有效的利用这些废弃物，使它们能够被二次利用并能较以前有更好的性能。68161

轻集料混凝土具有轻质高强、高耐久、保温、隔热、抗震、隔声等一系列优点，这归功于轻集料陶粒自身的特性，与传统的石子、砂等集料相比，轻集料是具有内部多孔且质轻的独特结构。利用这些固体废弃物，制成轻集料作为骨料加入到混凝土中，制成高性能混凝土，既能有效地解决固体废弃物的处理问题，又能大大缓解资源的消耗缓解自然的压力。但由于我国在该方面的生产研究起步比较晚，工艺设备发展落后，导致我国生产的轻骨料大多吸水率大、密度偏大、粒型大一、强度较低。我国在这一方面技术还不成熟的同时，城市的大量高层建筑建设、大跨度桥梁等正迫切要求使用高性能轻集料建筑材料。这一系列的问题时刻在催促着人们，因此，在这种大环境的压迫下为轻集料混凝土的发展提供了广阔的发展空间。

本文旨在利用废弃的粉煤灰、砂加气制备高性能的粉煤灰加气硅酸盐陶粒，然后，并对制成的陶粒进行一系列的处理，使陶粒的吸水率能够大幅度将低，陶粒混凝土的强度、耐久度等能够大幅度提高。学会如何制备陶粒并通过预湿处理、憎水处理、包壳处理以及陶粒混凝土的制备研究陶粒其及混凝土的性能，能够得到经济、简单、合理的高性能混凝土的制作工艺。

Title  The preparation and properties of high performance lightweight ceramsite research.

Abstract 

Along with our country economy fast development, the development of China's urbanization process and the renovation and demolition of old roads, houses and, more and more solid waste can not be effectively and timely processing, discarded, put, and solid waste landfill in China's environment and people's quality of life has a great influence. At the same time, due to the large number of buildings built, the consumption of resources is being rapidly in our country, more aggravate the deterioration of the environment. Therefore, how to effective use of these waste, allowing them to be secondary utilization and can have better performance than before.

Lightweight aggregate concrete has light weight, high strength, high durability, heat preservation, sound insulation, seismic, and a series of advantages, this is due to the nature of the light aggregate ceramsite, compared with the traditional gravel and sand aggregate, lightweight aggregate is a unique structure with internal porous and light. Made use of these solid wastes, light aggregate added to concrete as aggregate, made of high performance concrete, which can effectively solve the problem of solid waste treatment, and can greatly alleviate alleviate the pressure of the natural resource depletion. But due to production in the aspects of the research in China started relatively late, development process equipment backward, causes our country produces most of the lightweight aggregate bibulous rate is large, density is larger and larger grain type, intensity is low. In this respect technology in China is not mature at the same time, the city of high-rise building construction, long-span Bridges are urgently require the use of high performance light aggregate construction materials. This time a series of problems in urging the people, therefore, in this under the pressure of environment for the development of lightweight aggregate concrete has provided a broad space for development.
