摘要
通过试验和数学灰色关联分析,探讨了工厂生产条件下余浆品质对混凝土砖强度和收缩等方面的影响。结果表明,对砖强度影响最大的是余浆的密度和固含量,其次是水化程度。余浆水化程度与砖的干燥收缩率有关,通过控制余浆密度可保证混凝土质量;对于干燥收缩的控制,可从余浆预处理和改进工艺方面着手。
Through the tests and mathematics grey relational analytical method,the effects of slurry quality under factory production condition on strength and shrinkage of concrete bricks are discussed.The results show that the density and solid content of slurry are the most effective factors to the strength of bricks,and the hydration degree is the secondary factor.The hydration degree of slurry is correlated with the drying shrinkage ratio of bricks,and controlling the slurry density can ensure the concrete quality.To control the drying shrinkage,the measures of slurry pretreatment and improving the process can be made.
