本文对粉煤灰高性能混凝土的各项性能作了详细的研究，并针对粉煤灰的掺入量对混凝土各
种性能的影响以及粉煤灰混凝土在施工中应注意的一些问题进行了分析和探讨。
1．概 述
粉煤灰作为一种工业废料，资源丰富、价格低廉，且含有大量的活性成分，是现代混凝土中非常重要的一个组分。优质粉煤灰合理地应用于混凝土中，不但能部分代替水泥，节省工程造价，而且，其特有的性能可以很有效地用于各种使用要求的混凝土中，改善和提高混凝土的性能，是高性能混凝土中的理想掺和料。在现代混凝土中，粉煤灰已经与水泥、集料、水、外加剂同样重要，成为混凝土中的一个组分。粉煤灰高性能混凝土是以耐久性为主要目标进行设计的混凝土。它以优异的耐久性（而不是高强度）为主要特征，也就是说，任何强度等级的混凝土都可以做成高耐久性混凝土。为达到高耐久性，粉煤灰混凝土应具备的性能是：在新拌状态有良的工作性，即高流动性而不离析、不泌水，以使成型均匀、密实，水化硬化早期的沉降收缩和水化收缩小，温升低，硬化过程干缩小，以达到无初始裂缝，硬化后的渗透性低。

Every performance of this text to high-performance concrete of fly ash has done detailed research, and to the concrete respectively to person who mix of fly ash Kinds of influence of performance and fly ash concrete some questions that should notice carry on analysis and discussion in not constructing.
1. Summary
Fly ash, as a kind of industrial waste material, resources are abundant , cheap, and contain a large amount of active composition , it is modern concrete Central Africa A often important component part . The high-quality fly ash is applied to the concrete rationally , not only can replace the cement partly , save the fabrication cost of the project, And, its peculiar performance can be used in the concrete of various kinds of instructions for use very effectively, improve the performance of the concrete, It is the ideal in the high-performance concrete that admixes the material . Among it is at concrete not modern, whose name is already with cement in fly ash, collect material , water , admixture and Kind is important, become a component part in concrete. Fly ash high-performance concrete regard durability as main goal go on design mix Congeal the soil . It regards excellent durability (instead of the high
