HOW TO PRODUCE GOOD QUALITY CONCRETE? CivilBlog.Org

Oct 24, 2014A concrete is said to be of good quality, if it is strongest, densest, most workable and most economical for the job for which it is prepared. Amount of cement used in concrete should be low and that of aggregate should be high. If the following general requirements are fulfilled, then we can produce the []

How Concrete is Made Portland Cement Association

A mixture that does not have enough paste to fill all the voids between the aggregates will be difficult to place and will produce rough surfaces and porous concrete. A mixture with an excess of cement paste will be easy to place and will produce a smooth surface; however, the resulting concrete is not cost-effective and can more easily crack.
