How do you check the quality of a block?
1. You can check the quality of the solid concrete blocks on site by following some simple methods as given below….Field test for the solid concrete blocks
- Drop test. Randomly select one block from the total no.
- Corner test.
- Chisel test.
- Nail test.
- Texture.
- Shape & size.
How do you find the compressive strength of a solid block?
The compressive strength of a concrete masonry unit shall be taken as the maximum load in Newtones divided by the gross cross sectional area of the unit in square millimeters. Report to the nearest 0.1 N/mm2 separately for each unit and the average for the 8 full units.
What is the compressive strength of block?
For normal, medium weight concrete block, load- bearing, hollow or solid, their compressive strength is about 12.5N/mm2 or 125kg/cm2. For denser, higher weight concrete block, load- bearing, hollow or solid, their compressive strength is about 17.5N/mm2 or 175kg/cm2.
How do you test the strength of bricks?
Procedure of Compressive Strength Test on Bricks
- Place the specimen with flat face s horizontal and mortar filled face facing upwards between plates of the testing machine.
- Apply load axially at a uniform rate of 14 N/mm2 (140 kg/cm2) per minute till failure occurs and note maximum load at failure.
What are the quality tests for mud blocks?
Strength Analysis of Stabilized Mud Blocks

What are the tests for concrete?
Different quality tests on concrete such as compressive strength tests, slump tests, permeability tests etc….Tests on Hardened Concrete
- Compressive strength.
- Tensile strength.
- Modulus of elasticity.

What is compressive strength test?
compressive strength test, mechanical test measuring the maximum amount of compressive load a material can bear before fracturing. The test piece, usually in the form of a cube, prism, or cylinder, is compressed between the platens of a compression-testing machine by a gradually applied load.
What are the tests for bricks?
Types of Tests On Bricks for Construction Purpose
- Absorption test.
- Crushing strength test.
- Hardness test.
- Shape and size.
- Color test.
- Soundness test.
- Structure of brick.

How many types of brick test are?
7 Different Types of Tests on Bricks Brick has a rectangular shape mostly used in building construction.
What are the test of bricks?
A brick undergoes the following tests to find out its suitability for the construction work : Crushing Strength Test. Water Absorption Test. Presence of Soluble salts or Efflorescence Test.
How to check the quality of solid concrete blocks on site?
You can check the quality of the solid concrete blocks on site by following some simple methods as given below. 1. Drop test Randomly select one block from the total no. of blocks of the particular batch. Lift the block at about 4 to 4.5 feet which is nearer to your chest level and drop it on the hard ground surface.
How to find the density of a block?
The density of block is determined from the below relation and the average density of 3 blocks will be the final block density. Density of block = mass/volume (kg/m 3) Density values of different grades of blocks should be as follows.
What is the best way to measure the size of blocks?
The length, width and height are measured with steel scale. If it is a hollow block, then the web thickness and face shell are measured with caliper ruler. And prepare a report of average length, width and height of block and average minimum face shell and minimum web thickness using recorded dimensions.
How to test compressive strength of concrete masonry blocks?
Compressive Strength Tests on Concrete Masonry Blocks Eight blocks are taken to determine the average compressive strength of concrete masonry block. The blocks should be tested with in 3days after collected in lab. The age of each block shall be 28 days.
