The Nepal Building Code (NBC) specifies a Crushing Strength criterion of 35 kg/cm2 for bricks. However, in practice, crushing strength is usually higher. The water absorption of bricks should be 15% for machine manufactured bricks, while it could be up to 25% for hand moulded bricks, according to the Nepal Building Code. Brick Prices in Nepal

N/mm2 is the metric unit used in most countries, while Kg/cm2 is commonly used in Japan and a few other countries. The compressive strength of concrete blocks can range from 3.5 N/mm2 (500 Kg/cm2) to 40 N/mm2 (4500 Kg/cm2). The exact strength will depend on the type of block, its composition, and the testing methods used.

The average stress is 0.72 for concretes up to ultimate strength of 30 MPa (4000 psi). The factor γ indicates the ratio of breaking strength to the ultimate strength. γ =. Breaking stress Ultimate Stress ( f c ′ ) = 0.85 (average value) The ratio of average to crushing stress of concrete is denoted by β and is found for concrete of ≤ 30. 1.

Proof Load. Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. A material must remain in its elastic region when loaded up to its proof load typically between 85-95% of the yield strength. Acceptable clamp load is typically 75% of proof load.

3-Nov-2009. Cold crushing strength (CCS) of a refractory brick represents its strength. That is it tells us how much load that refractory can bear in cold conditions. The concept of testing CCS of a refractory material has perhaps, come from metallurgy. This is because for any refractory brick it is rather; rare that it would fail simply due to ...

After that crushing is done in the usual way. The cube can be tested after 3, 7, 14 and 28 days. Cube is placed in compression testing machine and axial load is applied at the rate of 140 kg/ cm2. In actual concrete is required sufficient time to gain strength. Usually 28 days strength is considered as the full strength of concrete.

Empirical Formula for Estimating Flexural Strength of Concrete. As per IS 456 2000, the flexural strength of the concrete can be computed by the characteristic compressive strength of the concrete. Flexural strength of concrete = 0.7 sqrt ( fck) Where, fck is the characteristic compressive strength of concrete in MPa.
