The compressive strength gained by concrete is thus measured at its 28th day after which the rate of strength is lowered. The compressive strength gained at later ages are tested by means of non-destructive tests. The table-1 below shows the rate of strength gained from the first day to 28th day. Table.1 Strength Gained by Concrete With Age.

This is based on the correlation values with the compressive strength test. The advantage of the pull off test is that the same equipment is used to measure the bond strength of plaster mortar. The quality of concrete repairs is also determined by the bond strength measurement between the repairing materials and the concrete sub-strata.

Compressive strength is ability of material which resist or withstand against compressive load acting both face along rising length (cross-sectional area) by reducing its size prior to failure. It is resistance of material against pushing force in equal and opposite direction. Tensile strength is ability of material with resist or withstand against tensile load acting on both face along rising ...

Jun 04, 2015 Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but

Aug 25, 2016 Reinforced Baked Clay (RBC) seems to be potential alternative of Reinforced Cement Concrete (RCC) for construction of low cost houses. In order to utilize RBC as a construction material for buildings, it is necessary to understand compression behaviour of baked clay. In this paper, relation between cube crushing strength and cylinder strength of baked clay is presented.
