提高粉煤灰水泥早期强度

A study on the increase of the early strength of fly ash cement

针对粉煤灰水泥早期强度低的缺点 ,研究了各种提高水泥早期强度的方法 ,并实验验证了采用这些方法的效果 ,通过采取一系列措施 ,使高掺量粉煤灰水泥的强度达到了 42 5

Some methods to increase the early strength of fly ash cement has been researched,with the aim of overcoming the low early strength of the fly ash cement and the effect of these methods had been verified.With the measurements taken,the strength of the cement had reached the 425 # standard,when the amount of fly ash added has increased to 30%.
