普通混凝土砂石级配的研究

Study on the Gravel-Sand Grading of Normal Class Concrete

摘要:

从传统的连续级配密实堆积入手,通过系统的试验研究,将传统的2个常用的连续级配计算式,依5种流变性类型混凝土调整为5个计算式,并得出了5种类型拌合物的最佳石子用量,明确了砂率随胶结材用量变化的规律.

Abstract:

The author's study of continuous compact deposit grading of aggregate through(systematic) experimental research lead to extend the two conventional formulae of continuous grading to five formulae depending on five rheological types of concrete mixtures.Thereafter the optimal gravel contents for the five mixture types are respectively obtained.And it is also established that the sand rate(SR) is changed along with the amount of cementing paste no matter what kind of concrete is used.
