WATER ABSORPTION TEST ON BRICKS

(IS: 1077 -1973)

 

OBJECT: To determine the percentage of water absorption of bricks

APPARATUS:

A touchy equalization fit for weighing inside 0.1% of the mass of the example and ventilated stove.

SPECIMEN:

total 3 random selection of bricks should be done

PROCEDURE:

(I)        Dry the example in a ventilated stove at a temperature of 105 °C to 115°C till it achieves a significantly steady mass.

(II)        Cool the sample to room temperature and get its weight (M1) example too warm to even think about touching will not be utilized for this reason.

(III)      Immerse a totally dried sample in clean water at a temperature of 27+2°C for 24 hours.

(IV)     Remove the sample and clean any excess of water with a moist fabric and take weight of given sample after it has been taken out from water (M2).

CALCULATIONS:

Water ingestion, % by mass, following 24 hours inundation in cool water is given by the equation,

The average result shall be reported.

Result

Water absorption of the given bricks = 15 %

Determination 

At the point when tried as over, the normal water retention will not be over 20% by weight up to class 125 and 15% by weight for the higher class.
