### coarse aggregate cement ratio of no fine concrete

“Fine aggregate” is defined as material that will pass a No 4 sieve and will, for the most part, be retained on a No 200 sieve For increased workability and for economy as reflected by use of less cement, the fine aggregate should have a rounded shape

No-Fines Concrete is a lightweight concrete made up of only coarse aggregate, cement and water by omitting fines (sand or fine aggregates) from normal concrete Advantages, limitations and mix proportions of no-fines concrete is discussed

Concrete is a mixture of cement, sand (fine aggregate), small stone or gravel (coarse aggregate) and water It has many applications, from fence posts to motorway bases and, because of this, there are many different concrete mix ratios that the constituents can be mixed to with each resulting in a different strength

Moreover, some conventional concrete maybe need 035-055 fine/coarse aggregate ratio limitations, on the other hand, in the self compacting concrete design as a special concrete we have to use .

No fines concrete may be defined as concrete mixtures containing little or no fine aggregate The fine aggregate is not added in this concrete so that there are voids left in the coarse aggregate The coarse aggregate may be any of the usual type or the light weight aggregate
