There are two kinds of concrete hollow blocks load-bearing concrete hollow blocks and non-load bearing concrete hollow blocks.

The voids are generally filled with mortar of lightweight aggregate material as well. Normally, concrete hollow blocks have voids of ¼ its gross area and the solid area should be not less than half of its area to attain its maximum allowable load capacity, study suggests. Hollow concrete blocksĬommonly used in the construction industry, concrete hollow blocks are usually manufactured using lightweight aggregates with a certain design load depending on the nature of the member it will be used into. So, if you want to know more about concrete block or concrete masonry units here are the 7 types of concrete block and the most common type of concrete blocks used in the construction industry. Now, if you want to build a concrete block or concrete masonry unit you need to have an Understanding About Checklist to compliance to the approved project documents such as blockwork shop drawing, method statement for blockwork, and inspection and test plan. These are generally made up of concrete and aggregates of certain design mixtures depending on strength required but systems used as masonry units are non-load bearing in nature or do not and should not be allowed to carry any vertical loads at all.
