Advantages of hollow concrete blocks: 1. The good concrete compacted by high pressure and vibration gives substantial strength to the block. Proper curing increase compressive strength of the blocks. 2. Low maintenance, Color and brilliance of masonry3.
Findings of the study revealed that as the percentage of rice husk ash in the mix was increased, the compressive strength of concrete hollow blocks decreased. Furthermore, concrete hollow blocks containing 40% rice husk ash were not good enough to be used as load or non-load bearing partition concrete hollow blocks but blocks containing 20% ...

4.3 Compressive strength of concrete paving blocks The 7 days and 28 days mean compressive strength of concrete paving blocks of different thickness for M30 grade have been presented in Table 3. Corresponding theoretical minimum average 28 days strengths (Calculated as per 15658:2006, Dowson 1980) are also presented in the same table.
Modulus of Elasticity of Concrete can be defined as the slope of the line drawn from stress of zero to a compressive stress of 0.45f’c. As concrete is a heterogeneous material. The strength of concrete is dependent on the relative proportion and modulus of elasticity of the aggregate. To know the accurate value of elastic modulus of a ...

The masonry units are tested in accordance with ASTM C 67 to determine compressive strength. Mortar is analyzed for chemical composition. The masonry strength can be estimated using Tables 1.6.2.1 and 1.6.2.2 in ACI 530-88. The fourth way to test the compressive strength in the wall is to use a flat jack as described in ASTM C 1196-91.
The maximum strength gain spike is observed till 14 days, so we test concrete at an intervals of 7 days, 10 days & 14days and If concrete fails to show results of 90% of its overall strength @14 days then that batching is rejected. Compressive Strength of Different
