Report on Cooperative Experiments on Relationship between Strength and Void Ratio of Porous Concrete
By Technical Committee on Establishment of Construction and Quality Control Standards for Performance-based Design of Porous Concrete
Concrete Journal, Vol.54, No.4, Apr. 2016
- Synopsis
- This report introduces the results of cooperative experiments carried out by the Technical Committee on Establishment of Construction Standard and Quality Control Standards for Performance-Based Design of Porous Concrete. The Committee presents the draft proposal of a strength control method that uses a strength ratio-void ratio relation formula. The results of these common experiments verify the relationship between strength ratio and void ratio, and empirical constants for this relational formula are proposed, but each organization ought to determine appropriate empirical constants for practical application. The process that led to the present proposal is described while introducing the results of the common experiments.
