Testing of Concrete Masonry Blocks for Compressive

Oct 31, 2016· Density of Concrete Masonry Block. As said above, 3 blocks shall be taken to conduct this test. To determine the density of block, first heat the block in the oven to 100 o c and then cooled it to room temperature. Now take the dimensions of block and from that find out the volume and weigh the block.

GUIDANCE FOR SPECIFIERS AND Concrete Ireland

‘Category’ of block which is defined in I.S. EN 771-3. Strength Testing of Concrete Blocks I.S. EN 771-3 requires that concrete blocks are compressive strength tested in accordance with I.S. EN 772-1. This test method requires that blocks are mortar capped before testing whereas the traditional test method used a soft board cover to the block.
