ACI PRC-211.6-14 (Reapproved 2023) TechNote: Aggregate Suspension Mixture Proportioning Method
| Published By | Publication Date | Number of Pages |
| ACI | 2014 | 11 |
This document describes the aggregate suspension mixture proportioning method. The method is suitable for normalweight concrete with workability ranging from zero-slump to self-consolidating. This method may not be suitable for mass concrete mixture proportioning. It is adapted from a method originally published by Koehler and Fowler (2007). TechNotes are a committee document that are narrowly focused, single-topic guides, usually practice oriented, that present a specific direction on a particular issue. ACI committee documents (including TechNotes) are reviewed and approved by ACI’s Technical Activities Committee. Keywords: durability; optimal grading; packing density; proportioning; shape-angularity factor; water-powder ratio; workability.
