Compressive Strength of Concrete  Cube Test,
Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes @28 days. Compressive strength of Concrete and its importance: As we all know that concrete is a mixture of sand, cement, and aggregate . 
Strength of Concrete  University of Washington
(compressive strength). At a given w/cratio, mortar is stronger than the corresponding concrete. Cement paste and aggregate are elastic, concrete The compressive strength of concrete is measured by a uniaxial compression test. i.e., load is progressively increased to fail the specimen within 2 to 3 minutes. 
Effect of Concrete Strength and Slab Thickness on Floor
The specifiion for the floor of a maintenance building called for a 6inch slab thickness and concrete with a design compressive strength of 3000 psi. The actual average cylinder strength for the floor concrete was 3630 psi. Four months after the floor was placed, 10 cores were drilled, measured, and tested in compression. 
Compressive strength  Wikipedia
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, 
Compressive Strength of Concrete Cubes  Civilology
Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days. 
Strength development in concrete  Understanding
Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. As the porosity increases, the compressive strength of the concrete will decrease. Soundness of aggregate: it will be obvious that if the aggregate in concrete is weak, the concrete will also be 
Standards for 7day and 28day strength test results
No strength test falls below the specified compressive strength by more than 500 psi (3.5 MPa) if the specified compressive strength is 5000 psi (35 MPa) or less; or by more than 10 percent of the specified compressive strength if the specified compressive strength exceeds 5000 psi (35 MPa). 
WHAT ARE THE FACTORS INFLUENCING COMPRESSIVE STRENGTH
Factors Affecting Strength Test Results of Concrete. Compressive strength is the most important property of concrete. The compressive strength of concrete is determined in the laboratory in controlled conditions. 
what is compressive strength of concrete?  Yahoo Answers
Nov 17, 2007· Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate. 
COMPRESSIVE STRENGTH TEST OF CONCRETE (IS:516
Compressive Strength Test on Concrete Procedure Representative samples of concrete shall be taken and used for casting cubes 15 cm x 15 cm x 15 cm or cylindrical specimens of 15 cm dia x 30 cm long. 
Compressive Strength Of Concrete  Civil Students

But Remember one thing that the compressive strength of the concrete should be in N/mm2. I made the also the video Lecture about this Article.Compressive strength has the same [] 
Strength of Concrete (PSI)  ProMatcher
The strength of concrete is measure in terms of pounds per square inch (or PSI). PSI is a measure of compressive strength, or the ability of the material to carry loads and handle compression 
Compressive Strength of Concrete  Definition, Importance
The compressive strength of concrete is about 4000 psi. Definition. Strength of hardened concrete measured by the compression test. The compression strength of concrete is a measure of the concrete''s ability to resist loads which tend to compress it. 
CIP 35  Testing Compressive Strength of Concrete
The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures. The compressive strength is measured by breaking cylindrical concrete specimens in a compressiontesting machine. The compressive strength is calculated from the failure load

The compressive strength is measured by breaking cylindrical concrete specimens in a compressiontesting machine. The compressive strength is calculated from the failure load divided by the crosssectional 
How to Evaluate Compressive Strength of Concrete 
It is safe to say that the compressive strength of concrete is the most important parameter used in the design of concrete structures; however, concrete does not provide significant tensile strength. Perhaps, this is the very fundamental idea of building reinforced concrete, where steel reinforcement provide the much needed tensile strength
