WHAT ARE THE FACTORS INFLUENCING COMPRESSIVE STRENGTH

Feb 26, 2015Compressive strength is the most important property of concrete. The compressive strength of concrete is determined in the laboratory in controlled conditions. On the basis of this test result we judge the quality of concrete. But sometimes the strength test results vary so widely that it becomes difficult to reach at any conclusion. Get price

Is the compressive strength of mortar important?

ANSWER: Compressive Strength. In load-bearing masonry, mortar compressive strength may have some importance, but mortar only contributes a small amount to masonry assembly compressive strength (f' m).). For ASTM C90 concrete block, the assembly compressive strength only increases 250 psi when the mortar is changed from Type N to Type S (from an f' m of 1750 psi to 2000 psi for Get price

Measuring Compressive Strength

Jul 01, 2005ASTM C39, Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens, specifies that the loading rate fall within 0.14 to 0.34 MPa/sec (20 to 50 psi/sec). On average, the compressive strength of cylinders tested at the high load rate limit will be 3% greater than cylinders tested at the low load rate limit. Get price

Difference Between Tensile and Compressive Stress

May 07, 2016Compressive stress is the opposite of tensile stress. An object experiences a compressive stress when a squeezing force is applied on the object. So, an object subjected to a compressive stress is shortened. Compressive stress is also defined as the force per unit area and denoted by the symbol σ. Get price

Formulas for Calculating Different Properties of Concrete

The most basic test done on concrete in most laboratories is the compressive strength test. Sometimes other properties of concrete such as tensile strength, modulus of elasticity, shrinkage values, etc are needed for design purposes. Researchers and Standards have come up with different relationships between thecompressive strength of concrete and other properties. In this post [] Get price

Brick masonry industrial chimneys: assessment, evaluation

In particular, it is commonly accepted that the ratio between the elasticity modulus and the compression strength of brick masonry varies between 700 (old brick masonry) and 1000 (new brick masonry) [8,11]. By knowing this, one can also estimate an average compression strength for the masonry by knowing its elasticity modulus. Get price
