Field test of bricks involves checking the physical properties and quality of bricks on-site.

• Visual inspection for cracks, chips, and uniformity

• Sound test by tapping the brick to check for a clear ringing sound

• Water absorption test by immersing the brick in water to see if it absorbs water

• Dimensional measurements to ensure uniform size and shape

• Strength test by applying pressure to check for breakage

Lab test of bricks involves checking for dimensions, compressive strength, water absorption, efflorescence, and soundness.

• Dimensions: Measure length, width, and height to ensure they meet standards.

• Compressive strength: Test the ability of the brick to withstand pressure.

• Water absorption: Determine the amount of water the brick can absorb.

• Efflorescence: Check for white deposits on the surface due to soluble salts.

• Sound...read more

Lab test of cement involves checking its physical and chemical properties to ensure quality and strength.

• Lab tests include checking fineness, setting time, compressive strength, and chemical composition.

• Fineness test determines the particle size of cement particles.

• Setting time test measures the time taken for cement to set.

• Compressive strength test evaluates the strength of cement mortar.

• Chemical composition test chec...read more

Field test of cement involves checking its physical properties and quality to ensure it meets standards.

• Field test involves checking the setting time of cement to ensure it is within specified limits.

• Checking the compressive strength of cement cubes after a certain period of curing.

• Inspecting the color and texture of the cement to ensure it is uniform and free from impurities.

• Measuring the fineness of cement particles ...read more
