In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). Geopolymer concrete is an innovative, eco-friendly construction material. In geopolymer concrete cement is not used as a binding material. Follow Published on Dec 12, 2016. Factual Civil Engineering 10,941 views 12:00 Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression loading. • The cube specimen is of the size 15 x 15 x 15 cm. COMPRESSIVE STRENGTH • The strength of concrete specimen depends upon cement, aggregate, bond, w/c ratio, curing temperature, and size of specimen. The characteristic strength is defined as the strength of the concrete below which not more than 5% of the …

If the largest nominal size of the aggregate does not exceed 20 mm, 10 cm size cubes may also be used as an alternative. It is used as replacement of cement concrete. The measured compressive strength of the cubes shall be calculated by dividing the maximum load applied to the cubes during the test by the cross-sectional area, calculated from the mean dimensions of the section and shall be expressed to the nearest 0.5 N/mm 2.

For cube test two types of specimens either cubes of 15 cm X 15 cm X 15 cm or 10cm X 10 cm x 10 cm depending upon the size of aggregate are … Objective The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (f ck)- as per Indian Standards (ACI standards use cylinder of diameter 150 mm and height 300 mm). Compressive strength as per American Codes.
