If HS is greater than 2.7m, the compressive strength of bricks or blocks used in the wall should be at least Condition B, or as indicated by the key, whichever is the greater. If the external wall is solid construction, the masonry units should have a compressive strength of at least that shown for the internal leaf of a cavity wall in the same position. The guidance given in the diagram for ...

Properties of Concrete Blocks — Strength

Actual tests of compression strength of hollow concrete blocks are difficult to make, because it is almost impossible to apply the load uniformly over the whole surface, and also because a block 16 inches long and 8 inches wide will bear a load of 150,000 to 200,000 pounds, or more than the capacity of any but the largest testing machines. Three one-quarter blocks, 8 inches long, 8 inches wide ...

Compressive strength and deformation characteristics of ...

The influence of block types on the compressive strength was investigated by Thamboo et al. [36], in which two core hollow blocks and H shape blocks were used to examine the compressive behaviour; the H shape block with single web-shell failed at relatively lower strength than the conventional hollow block prisms. Hence, it could be hypothesised that the hollow blocks with higher web-shell ...

STRENGTH AND ELASTIC PROPERTIES OF AERATED CONCRETE BLOCK ...

The compressive strength of the block is the main contributing factor for the strength of masonry. IS: 2185 (Part-I) (1979) specifies the minimum compressive strength for three types of units. They include hallow (load bearing), hallow (non-load bearing) and solid (load bearing). The minimum compressive strength for a non-load bearing unit is 1.2 MPa while that for a load bearing unit, it ...

Normalised Strength of Aggregate EPIC Concrete Blocks

compressive strength test method (BS EN 772-1). The factors given in BS EN 772-1 generally require interpolation to establish the factors for common UK block sizes. Table 1 gives interpolated shape factor corrections. * 100mm high units are units laid flat. Unit strengths are usually given for units laid in their normal aspect and not laid flat. Laid flat strengths are usually several times ...

Load Carrying Capacity of Hollow Concrete Block Masonry Column

The mean of the compressive strength of the three blocks will be taken as the compressive strength of batch compressive strength less than 75% of the mean value so obtained. Mortar should be spread over the entire top surface of the block including front and rear shells as well as the webs to a uniform layer of one centimeter thickness. Normally full mortar bedding should be adopted as it ...

Compressive strength of masonry constructed with high ...

During compressive testing of masonry walls constructed with high-strength blocks and with mortar with moderate, aproximatelly strength between 70 and 150% of that of the block, the mortar has a greater tendency to expand laterally in relation to blocks, because the later has a higher stiffness. However, the mortar is confined laterally on the block-mortar interface; therefore. shear stresses ...
