新型混凝土层出不穷,有不少新品种的外加剂也相继问世,各种掺合料被开发利用后变废为宝,其中粉煤灰和外加剂的应用也大大改善了混凝土的性能。在普通混凝土中掺人粉煤灰和外加剂是混凝土材料今后发展的方向之一,同时也是实现可持续发展,保护生态环境,发展绿色高性能混凝土的有效途径之一,有着重要的社会经济意义。甘肃地区地处黄土高原,硫酸盐含量丰富,对桩基础混凝土的腐蚀较为严重,而研究表明,一定粉煤灰掺量的混凝土可一定程度抑制硫酸盐腐蚀。本文就高掺量粉煤灰高性能混凝土在工程中的实际应用情况进行分析。
New concrete endless, many new varieties of additives have also come out one after another, all kinds of admixtures after the development and utilization of turning waste into treasure, fly ash and additives which also greatly improve the performance of concrete. It is one of the effective ways to realize sustainable development, protect the ecological environment and develop green high-performance concrete. It has important socio-economic significance . Gansu is located in the Loess Plateau, rich in sulfate, corrosion of concrete pile foundation is more serious, and studies have shown that a certain amount of fly ash concrete can inhibit sulfate corrosion to some extent. This paper analyzes the practical application of high-volume fly ash high performance concrete in engineering.
