### 5 MATERIAL TESTING AND PRACTICE

A variety of institutions, eg universities, civil engineering, etc will normally have the facilities to carry out the tests It is usual to produce six cubes at a casting and send two 100 mm cubes for testing at seven days, 28 days, and 96 days, after castingTop 6 Important Quality Tests Of Concrete By Noel Mades Posted on August 5, In Test 63 Comments , The size of cube sample is 150 mm and tested in accordance to BS -122 6 Initial Surface Absorption Test , Always at fingertips thanks to Kit briefcase.

### Compression Test on Concrete

Compression Test of the Concrete Specimen is most widely used test to measure its compressive strength Two types , relative humidity of 90 percent is to be maintained always The cube is demoulded just before testing at 24 hours , The compressive strength is found to be highest for the cube specimen 150 mm and belowThe volume of a cube is given by its length cubed, (length) 3 Thus, the basic SI unit of volume is the cubic meter, or m 3, the volume of a cube that is 1 m on each edge Smaller units, such as cubic centimeters, cm 3 (sometimes written as cc), are frequently used in chemistry.

### Why we use 150mm size cube for compressive strength ,UTM

Jan 28, But we use other cube sizes for different specific purposes like we test 100 mm cubes for concrete made of 10 mm coarse grain material Also, we test 400 mm size cubes for concrete used in airports Apart from cubes, we use cylinders too for concrete testingA Universal Testing Machine (UTM) is used to test both the tensile and compressive strength of materials Universal Testing Machines are named as such because they can perform many different varieties of tests on an equally diverse range of materials, components, and structur.
