  • Which is Stronger – Concrete Blocks or Conventional Bricks

    · The strength of a concrete block or brick wall depends on the mortar holding the blocks together Mortars that are rich in lime are weaker than mortars thatActual 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 onequarter blocks, 8 inches long, 8 inches wideProperties of Concrete Blocks — StrengthEight blocks are taken to determine the average compressive strength of concrete masonry block The blocks should be tested with in 3days after collected in lab The age of each block shall be 28 days The compressive strength testing machine consist of two steel bearing blocks, one is in rigid position on which the masonry unit is placed and another one is movable which transmit the load toTesting of Concrete Masonry Blocks for Compressive
