Compressive Strength Compressive strength tests are used to ensure that concrete masonry units meet the minimum strength requirements of the applicable unit specification (see ref. 11). The unit compres-sive strength results may also be used to verify compliance with the specified compressive strength of masonry, f’ m, when
that the moisture content in concrete does have a significant effect on the compressive strength of concrete, but has a much lesser effect on the split tensile strength. As the specimen degrees of saturation increased, the compressive strength fell. However, at nearly saturated condition, an increase in compressive strength can be found.
Typically concrete cubes are cured and tested in a manual or automatic concrete compression machine at 7 days and 28 days to assess compressive strength. ELE’s comprehensive range of concrete compression machines is able to test concrete, mortar and cement samples such as cubes, cylinders, flagstones and beams.
concrete compressive stress block to neutral axis depth (c). An ideal equivalent rectangular concrete stress block should give a precise representation of the magnitude and location of the resultant concrete compressive force in order to provide an accurate estimate of the ﬂexural strength of RC members.
Fd = maximum design compressive strength (kN/m) = k Fo Where: k = reduction factor for slenderness and eccentricity from Table 7.1 of AS 3700.

1986). The compressive strength results for the concrete masonry units are summarized in Table 2. The block strength was based on its average net area in accordance with CSA A165.1 (2004), and computed as 38,300 mm². Table 2: Concrete Block Unit Compressive Strength Test Results Nominal Strength (MPa) Supplier Reported Strength
Compressive strength, tensile strength and modulus of elasticity of concrete were tested at 1, 7 and 28 days of hardening and at a day, when concrete ring was cracking. Cube specimens 100 mm and 150 mm were used for compressive strength, cubes 100 mm for tensile strength, and cylindrical specimens measuring 150×300 mm for modulus of elasticity.
