Components of Block Construction: AAC Blocks, Cement, and Sand

Combining AAC Blocks, Cement, and Sand for Strong Structures

Constructing with concrete blocks has gained popularity in the realm of construction projects. Concrete blocks offer swifter construction compared to traditional bricks, with the added advantage of significantly reduced mortar consumption, slashed by over half. However, it’s essential to note that the total cement needed for both the blocks and mortar exceeds what’s necessary for a brick wall’s mortar. This article delves into the quantities of AAC blocks, cement, and sand requisite for block construction.

Autoclaved Aerated Concrete (AAC) Blocks

Autoclaved and aerated (AAC) blocks have become a popular choice for construction projects due to their unique properties. These blocks are characterized by their abundant air bubbles, which result in an approximately one-fifth reduction in material usage compared to regular concrete. AAC blocks boast attributes such as lightweight composition, fire resistance, and excellent thermal insulation. The quantity of AAC blocks necessary for a project, hinges on block dimensions and the surface area to be covered.

Cement plays a pivotal role in crafting concrete blocks. The quantity of cement demanded by a project is contingent on block size and coverage area. Concrete blocks can be fashioned using 1:3:6 concrete with a maximum aggregate size of 10mm or a cement-sand blend with ratios spanning 1:7, 1:8, or 1:9. To ascertain the cement quantity required for a project, one can compute the number of blocks needed and the cement allotment per block.


Another vital ingredient in the concoction of concrete blocks is sand. Sand requirements for a project are predicated on block dimensions and surface area coverage. As a rule of thumb, for every 100 standard-sized blocks being set, you can requisition approximately 600 to 800 pounds of sand. The sand quantity essential for a project can be ascertained by estimating the number of blocks needed and the sand allocation per block.

In summation

The quantity of AAC blocks, cement, and sand requisite for block construction hinges on block dimensions and surface area coverage.
