摘要
粉煤灰可用于水泥混凝土的制备,可节约水泥和砂。它不但能提高混凝土的工作性能,同时对保证混凝土的力学性能也有积极的意义。粉煤灰在葫芦岛市桥涵构造物混凝土中应用相对较少,本文以猫眼河大桥为研究背景,介绍了粉煤灰混凝土的配合比设计及应用。
Fly ash can be used to make cement concrete.It can save cement and sand.Not only it can improve the technology properties of concrete,but also it has a positive significance to ensure the mechanical properties.Relatively less research had been carried out on the use of fly ash in bridge structure concrete in Huludao city.As researching object of Maoyanhe bridge,the article elaborates the proportioning design and application of fly ash concrete.
