摘要
据有关技术资料表明,同时具有良好的和易性及强度的流态混凝土,其水泥浆体积与集料体积之比一般为35∶65[1],即Ve:(Vs+Vg)=35∶65.在此事实基础上,结合我国现行粉煤灰混凝土设计规范,提出了最佳体积比流态粉煤灰混凝土配合比设计方法[2],经试验证明,配制粉煤灰流态混凝土体积比例改为36∶64更为合理,并应用于十几个实际工程,取得了良好的经济效益和社会效益.
It was show that the concrete possesed of higher strength and better workability at the same time has been proved,Which the ratio of the cement mud volume to the aggregates volume is usually 35∶65,i.e.V_e:(V_s+V_g)=35∶65.combined with current fly ash concrete design standards in China,Design method and test of best volume ratio for fly ash with high slump concrete were raised.The ratio of the cement mud volume to the aggregates volume is usually 36∶64 ,which have gained nicer benefit of economy and society in the more than ten engineering projects.
