Testing High-Strength Concrete Compressive Strength

1993-7-1  Testing high-strength concrete (HSC) for compressive strength puts into doubt a certain number of concrete testing practices. First, most testing laboratories are equipped with loading capacity machines inadequate for testing 150 x 300-mm (6 x 12-in.) specimens, thus limiting HSC specimens to 100 x 200 mm (4 x 8 in.) in size.

TESTING HIGH-STRENGTH CONCRETE COMPRESSIVE STRENGTH. Comparative testing reveals that high strength concrete (HSC) compressive strength values are greater by 5% when measured on 100 x 200 mm specimens. Moreover, the coefficient of variation on one set of three 100 x 200 mm specimens is as small as, or smaller than that for 150 x 300 mm specimens.

Why We Test Concrete Compressive Strength after 28 Days?

After 14 days of casting concrete, concrete gains only 9% in next 14 days. So, rate of gain of strength decreases. We have no clear idea upto when the concrete gains the strength, 1 year or 2 year, but it is assumed that concrete may gain its final strength after 1 year.So, since the concrete strength is 99% at 28 days, it's almost close to its final strength
