How can I compare compressive strength from crushing
1. In general, a lot of literature is available on compressive strength of cube or cylinder specimens. However, in practice, reinforced concrete is used in the field, especially for large structures.

Transcribed image text: Small sample: Twenty concrete blocks were sampled and tested for crushing strength in order to estimate the proportion that were sufficiently strong for a certain application. Eighteen of the 20 blocks were sufficiently strong. Use the small-sample method to construct a 90% confidence interval for the proportion of blocks that are sufficiently strong.

SCC Concrete Solid Blocks
Every batch goes through a stringent Consistent Compressive Strength Check. Besides strong concrete blocks, the customers have a great advantage of the superior finish of the blocks with IS standards which reduces the mortar consumption during plaster work. The process of maintaining quality products begins from quality checks of the raw materials.

Towards a simple compressive strength test for earth bricks?
strength measured on “standard” specimens (cubic or cylindrical specimens) could not be compared to that of the bricks. The literature showed that many international standards specified the use of procedures drawn up for fired bricks or concrete blocks for the measurement of the compressive strength of earth brick (Walker 1996).

Two blocks 6X8X9 inches, 22 months old, showed crushing strength of 2,530 and 2,610 pounds per square inch. These blocks were made of cement 1.25 parts, lime 0.5 part, sand and gravel 6 parts, and were tamped from damp mixture.

Compressive Strength of Concrete and Concrete Testing
Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. In other words, we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. Based on the test results, conformity can be checked as per the relevant standards.

Properties of Bricks – Compressive Strength -Hardness
Compressive Strength of bricks. Generally, bricks have high compressive strength in the range of 5.5 N / mm 2 to 140 N/mm 2. If the crushing strength of the bricks is less than 3.5 N/mm 2 it must not be used. A field test about strength of the bricks is to fall the brick from a height of 1 meter and it must not break in to pieces.

The range of strength for sandcrete blocks specified by N.I.S 74:1976 is between1.8N/mm2 to 2.5N/mm2 as the minimum strength. The blocks can cope with thermal and moisture conditions, and the problem of algae growth on the face of block work during construction is unlikely to affect the strength of the block (Edward, 1985).
