Experiment no. 07

Experiment name: Determination of compressive strength and absorption capacity of bricks

Objective

The objective of this experiment is to,

1. Determine the compressive strength of bricks
2. Determine the absorption capacity of bricks.

Significance

1. The absorption capacity helps in understanding the water retention characteristics of bricks.
2. Compressive strength is a key indicator of the brick’s ability to bear loads.
3. Understanding both properties allows comparison against industry standards.

Apparatus

1. Balance
2. Compression Testing Machine
3. Measurement devices
4. Capping equipment

Data sheet & calculation

Result

The absorption capacity of brick sample 8 and 2 is 12.67% and 11.76% respectively. And the compressive strength of brick sample T and A is 23.54 MPa and 21.66 MPa respectively.

Discussion

Brick samples 2 and 8 showed absorption capacities of 11.76% and 12.67%, respectively. These values indicate a moderate water absorption rate, suggesting that both bricks can absorb water without exceeding typical thresholds for construction-grade materials.

The results show that brick T exhibited a slightly higher compressive strength (23.54 MPa) than brick A (21.66 MPa). Both bricks fall within acceptable ranges for standard construction bricks, demonstrating their ability to bear significant structural loads. However, the difference in strength might be attributed to slight variations in material composition or manufacturing quality.
