Mixture Proportioning Approaches for self-compacting concrete- A Review

Abstract

In the production and application of concrete, Mix design is a critical step. Many mix design methods have been proposed for self-compacting concrete (SCC), but these methods lacks a uniform criterion, specific design parameters or factors to evaluate their design process or procedures which makes it cumbersome to compare the effectiveness of these mix design methods for SCC available in the literatures so as to evaluate progress made so far and this provide valuable data to hekp select suitable mix design method(s) for SCC. On the basis of their principles, these approaches can be clasified into five groups such as rational mixture proportioning method, compressive strength mixture proportioning method, aggregate packing mixture proportioning method, staatistical and rheology of paste model mixture proportioning method respectively. Each mixture proportioning method was discussed based on their procedure, pros and cons. To obtain high quality SCC with satisfactory properties, appropriate method should be chosen in accordance with actual situation.
