The article presents the results of work by the AFREM/HPC group on the formulation of high-performance concretes. This is an updating of LCPC's grout method. The goal is a methodology making it possible, for a given binder (or mixture of binders), to determine the saturation doses of a certain number of superplasticizers and compare them in terms of their effectiveness and the duration of the ...

Transcribed image text: The design of a concrete mix requires 1650 lb/ft of coarse aggregate in dry condition, 1100 lb/ft of fine aggregate in dry condition and 300 lb/ft of mix water. The coarse aggregate has a moisture content of 0.8% and an absorption capacity is 1.5%. The fine aggregate has a moisture content of 1.1% and an absorption capacity of 1.3%.

🕑 Reading time: 1 minute Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.

This paste is also called as concrete. The strength of this concrete mix is determined by the proportion on which these cement, sand, stones or aggregates are mixed. There are various grades of concrete available in the market based on these ratios. Some of them are: M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent.
