Strength may be defined as the ability to resist applied stress: the greater the resistance, the stronger the material. Resistance may be measured in several ways. One is the maximum stress that the material can endure before "failure" occurs. Another approach is to measure the deformation or strain that results from a given level of stress before the point of total failure.

This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone & brick khoa of aggregates.

Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

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 many

Compressive strength test. This test is vital for evaluating the stone’s resistance to crushing loads. A wall stone has to bear the compressive load of the stone’s weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in. A
