SPECIFICATION FOR OPTIMIZED GRADED CONCRETE For Flowable Applications
Introduction
After evaluating almost 200 concrete mixtures for flowable concrete applications, our research team used the data to develop a specification for general ready-mix type concrete. Below is the recommended specification.

Figure shows the minimum and maximum limits.
Aggregate Specification
· The combined gradation must be within the boundary limits for each sieve size
· The total volume of coarse sand (#8-30) must be a minimum of 20%.
· The total volume of fine sand (#30-200) must be within 25% and 40%.
· Limit the flat or elongated coarse aggregate to 15% or less at a ratio of 1:3 according to ASTM 4791.
