COMPRESSIVE STRENGTH OF BRICKS





AIM: -
 compression strength of brick

OBJECT: -

The specimen brick is immersed in water for 24 hours. The frog of the Compressive Strength

APPARATUS:

Bricks,
Oven
Venire Caliper,
Scale, Etc.

FORMULA: -

                                          Max. Load at failure
Compressive Strength = -----------------------------
                                          Loaded Area of brick
         
THEORY: -

Bricks are used in construction of either load bearing walls or in portion walls in case of frame structure. In bad bearing walls total weight from slab and upper floor comes directly through brick and then it is transverse to the foundation. In case the bricks are loaded with compressive nature of force on other hand in case of frame structure bricks are used only for construction of portion walls, layers comes directly on the lower layers or wall. In this case bricks are loaded with compressive nature of force. Hence for safely measures before using the bricks in actual practice
they have to be tested in laboratory for their compressive strength.

PROCEDURE: -

1. Select some brick with uniform shape and size.
2. Measure its all dimensions. (LXBXH)
3. Now fill the frog of the brick with fine sand. And
4. Place the brick on the lower platform of compression testing machine and lower the spindle till the upper motion of ram is offered by a specimen the oil pressure start increasing the pointer engineering start
returning to zero leaving the drug pointer that is maximum reading which can be noted down.

          Compressive Strength = -----------------------------
                                                    Loaded Area of brick

RESULT : -



The average compressive strength of new brick sample is found to be ………. Kg/sq.cm.
