Early Age Tests to Predict 28 Days Compressive Strength of Concrete 84 designing concrete structures but strength is the most important one. An overall picture of concrete quality is reflected by the concrete strength. The process of strength growth is called 'hardening'. There are many factors which control compressive strength of concrete.

What is the Minimum Compressive Strength of Concrete N/mm2 in 7 day's. Compressive strength of concrete procedure : For cube test two types of specimens either cubes of 15cm X 15cm X 15cm or 10cm X 10cm x 10cm depending upon the size of aggregate are used. For most of the works cubical moulds of size 15cm x 15cm x 15cm are .

4. Compressive Strength of Concrete The strength of concrete is controlled by the proportioning of cement, coarse and fine aggregates, water, and various admixtures. The ratio of the water to cement is the chief factor for determining concrete strength as shown in Fig.(1). The lower the water-cement ratio, the higher is the compressive strength.
