Prediction of compressive strength of concrete from early

Prediction of compressive strength of concrete from early

ABSTRACT: In the construction process, it is always important to know the concrete compressive strength. The recommended procedure to ensure the concrete strength is to perform cylinder test. Test result of concrete cylinder at 28th day, represents the characteristic strength of the concrete that has been prepared and cast to form the concrete work....

Splitting Tensile Strength and Compressive Strength

Splitting Tensile Strength and Compressive Strength

Analyses of test results show that the compressive strength and splitting tensile strength are related, and an increase in one generally is similarly reflected in an increase in the other. The commonly accepted 0.5-power relationship between the compressive strength and the splitting tensile strength was found to be inaccurate at all ages....

CONCRETE COMPRESSIVE STRENGTH VARIATION WITH TIME

CONCRETE COMPRESSIVE STRENGTH VARIATION WITH TIME

After 10 years, the compressive strength decreased or remained essentially the same. MacGregor (1983) used the same study and formulated an equation of the relation between compressive strength and age; in the case of 28-day-specified compressive strength of concrete, this is equal to 281.5 kg/cm2 (27.6 Mpa)....

What is the relationship between hardness and the concrete

The shmedit Hammer still the most used devise for measuring the compressive strength by measuring the surface hardness (the rebound number R) taking into account all precautions recommended by the manufacturer and the relations drawn on the hammer itself, the percentage of error corresponding to each R value, and the concrete age that would not be less than 14 days and not more than 56 days, outside these age period, Shmedit hammer is good for comparisons only....
