INTRODUCTION TO MATERIAL TESTIG LAB If we believe God has created the world, then we will have to believe the Civil Engineers have built the modern concrete structures around the world. To design any structure, one has to plan and design it. To design a structure, materials are required.

Experiment- 1 SHAPE AND SIZE TEST OF BRICKS AIM OF THE EXPERIMENT: - To determine the shape and size test of bricks. THEORY: The bricks are the most commonly used building material. These are being commonly used for the construction of walls, columns, parapet walls, paving floors, and as coarse aggregate for concrete work in foundations, under-floors etc. At places where stones are not easily available, bricks replace the stones because there is plenty of clay available for the manufacture of bricks. The bricks do not required dressing and the art of laying brick is also simple. At many places the brick work can be carried out with the help of unskilled labours. But the brick should be purely rectangular in shape with corners exactly 90º and should satisfy the ISI recommended size. APPARATUS REQUIRED: (I) Measuring Tape (ii) Thread MATERIALS REQUIRED: - (i) Bricks of same brand and same lot. (20 no’s) PROCEDURE: 1) Randomly select twenty bricks of standard size (190x90x90) mm. 2) These bricks are stacked lengthwise, measure the total length of 20 bricks along length wise. 3) These bricks are stacked widthwise, measure total length of 20 bricks along width wise. 4) These bricks are stacked thickness wise, measure total height of 20 bricks along thickness wise.
