(IS: 1077 -1973)

AIM-  This test is performed to determine the accurate dimensions of the bricks.  

APPARATUS: Meteric Tape,  no of bricks 20-25 

THEORY-

The bricks are made of the natural source i.e. soil and burnt in a kiln at high temperature. therefore bricks are categorized in 4 different ways. In that first class, bricks are superior ones. they made with all proper tests and with accurate dimensions as per code says.

PROCEDURE-

1. Take 20 no. of bricks out of the given lot at randomly.

2. Remove loose particles of clay and small projections of the bricks.

3. Arrange them on a level surface in contact with each other and in a straight line.

4.     Take dimension of bricks first as lengthwise, then width, and then the height-wise.

4. Measure the overall length of 20 bricks of size 19 x 9 x 9 cm laid by means of a Tape.

 5. The Dimensions of 20 bricks should be within the following limits:

Standard Table by code-

S.No.	Class	Length	Width	Height/Depth
1.	Class A	368 - 392 cm	174 - 186 cm	174 - 186 cm
2.	Class B	350 - 410 cm	165 - 195 cm	165 - 195 cm
3.	Class C	Above 410	Above 195	Above 195

 

OBSERVATION-

Observations are then noted as shown below:

1. Total 20 bricks length = ………. cm

2. Total 20 bricks width = ………... cm

3. Total 20 bricks height = ……….. cm

RESULT-  This brick comes under class as  .......... bricks
