中文摘要
粉煤灰在混凝土中的应用是最为普遍的，利用的技术水平也是最高的。它是粉煤灰综合利用的主流，也是今后的主要发展方向。随着研究工作的深入，粉煤灰对混凝土各种性能的影响规律不断地被揭示，加之粉煤灰的资源化、商品化，其质量有了很大程度的提高，使得人们已不再将粉煤灰看成是“废物”而加以“利用”，而是积极地利用粉煤灰的各种优良特性来改善混凝土的性能。本文研究了采用普通原材料和常规生产工艺配制方法配制普通C40混凝土，同时与掺用粉煤灰和玻璃纤维的双掺配制混凝土通过试验进行对比，按L9(34)正交试验表设计混凝土的配合比,用极差分析法分析了混凝土拌合物的工作性能以及硬化后的3d、7d和28d混凝土的抗压强度、抗折强度等。经试验与优化分析,确定了混凝土适用配合比,并在工程应用中加以验证。经我们反复试验,采用混凝土双掺技术(掺合料和外加剂)制备了Ｃ40高性能混凝土。这种混凝土在标准养护箱养护28 这种混凝土在标准养护箱养护28天后其物理性能满足设计要求，同时满足流动性的设计要求，从而保证了工程质量。关键词：粉煤灰 混凝土 配合比设计 正交试验
ABSTRACT
The Influence Of Fly Ash In Concrete
The fly ash from stove is the most widespread in the application in the concrete, the technique level of the exploitation also is the highest.It is main development direction that the main current that the fly ash synthesizes the exploitation, also is from now on. Along with the study work through fly ash in concrete,that every kind of function of the influence regulation is announced to public constantly, the recycling that add its fly ash, commercialize, its quantity contain very big degree of exaltation, make people having no longer seen the fly ash is discards that ameliorative concrete that every kind of good characteristic but take into" make use of", but make use of the fly ash progressively to the function.This text studies the common and original material in adoption to produce with the normal regulations the craft prepares the method prepares the common the concrete of C40, using with the match of the fly ash to prepare with a match of the glass fiber at the same time the concrete pass to experiment to proceed the contrast, pressing L9(34) hand over the form that experiment the match design the concrete compares, analyzing with the very bad analysis method the concrete mix to match the work function of the thing and an anti-ford with a concrete of the hardening empresses press strength, anti-fold strength etc. Through experiment and excellent turn the analysis, make sure the concrete the suitable for use match compare, and take into the verification in engineering appliedly.Experiment again and again by us, adopt the concrete a match technique( the matches to anticipate with the in addition) system had the C40 high performance concrete.This kind of concrete protects a box of protecting in the standard 28 this kind of concretes protect in the standard the box protects 28 its physics in divas functions satisfies the design requests, satisfying the fluxion at the same time of design request, from but guaranteed the engineering quantity.Keywords：Fly ash，Concrete，Matching with the ratio designs, Hand over to experiment.
