The results are presented in tables and figures. It was found that the highest replacement level of 40 % by fly ash and 16 % by silica fume, simultaneously, a total replacement of cement to the extent of 56 % gave a 10 % increase in the 28day compressive strength compared to that of control concrete.

Compressive Strength of Concrete is an important element in designing Structure Compressive Strength of Concrete Consequently Quality of concrete manufactured is often measured by its Compressive Strength
to accurately predict the load at which cracking occurred. As the maximum compressive stress at prestress transfer was increased, a decline in cracking load prediction accuracy was observed. For the specimens subjected to high compressive stresses at release (greater than 'ci), the concrete in the precompressed tensile zone was

diameter by 300 mm compressive cylinder strength and the minimum 150 mm cube compressive strength. Concrete grades or strength classes denotes the compressive strength of concrete which is taken as the 28 days crushing strength of concrete cubes or cylinders [15].
The measured compressive strength of a core will generally be less than that of a corresponding properly molded and cured standard cylinder tested at the same age. For a given concrete, however, there is no unique relationship between the strengths of these two types of specimens (see Note 3). The relationship is affected by many factors ...

Measuring the compressive strength of concrete is achieved by taking a sample of concrete at the time of placement. Cylinders, measuring 12 in. high by 6 in. in diameter, or 8 in. by 4 in., are compressed by a break machine that exerts increasing force upon the cylinder until it structurally fractures.
