When the concrete stretcher block is used at the end of the openings, then the corner blocks are used to furnish it in the right manner. The concrete corner block is used at the end of the window and door. The size of the stretcher block is lesser than the hollow concrete blocks. The constituents of these blocks are the same as the hollow blocks except the size and shape. It is used to interconnect the masonry at the wall corner.

The concrete stretcher block is a subtype of hollow concrete blocks. The depth and size of lintel provision are varied based on the length of the opening. The groove will be filled with concrete along with the reinforcement. The lintel beam is provided over the door and window opening to furnish the wall work up to the ceiling. Lintel blocksĪ certain length and width of groove have been provided in the lintel blocks. It is used where the soil is consolidated based on the monsoon, and it is economical. Paver blocks are in the shape of rectangular and square, and installation has been done by interconnecting those blocks. You may know the paver blocks are used in the construction of street roads, car parking areas and pathways. The cost of concrete bricks is economical, and it may manufacture in different colours. The concrete bricks are available in size of 19cm x 10cm x 7.5cm, 22.5cm x 10cm x 7.5cm. The constituents of concrete bricks are mostly the same as the solid blocks. The concrete bricks are used to construct industrial buildings and compound walls. Generally, the AAC blocks are available in the size of 60cm x 20cm x 20cm, 60cm x 20cm x 15cma and 60cm x 20cm x 10cm. The finishing of the AAC block wall gives a smooth finish, but installation work is slightly tricky. So the usage of steel will be reduced at the range of 10% to 15%. It reduces the dead load of the structure. The AAC blocks are used in high rise buildings. The constituents of cement and aggregates are different compared to the solid blocks. Very thin and lightweight aggregates are used to manufacture the aerated autoclaved blocks.

The workability of hollow blocks is effortless because of its lightweight. The lightweight aggregates are used to manufacture these blocks. The presence of voids in hollow blocks is 25% of its gross area, and the solid area is more than 50%. The lightweight concrete is used to mould blocks called hollow blocks. The hollow blocks are mostly used in the construction of high rise buildings. The masonry method is the same as conventional bricks, but the workability of solid blocks is a little tough compared to the red bricks due to the weight of solid blocks. Normally solid blocks are available in the size of 80cm x 20cm x 20cm, 40cm x 20cm x 20cm and 40cm x 20cm x 10cm. The size of the solid blocks can be modified as per our requirement, and we can easily manufacture these types of blocks near to the site, so it reduces the construction cost. The dead load of the structure will be increased due to the weight of the solid blocks. The solid blocks used in the construction of the wall where the load occurs. The concrete blocks have been classified based on their material, usage and typical shapes as below. The concrete blocks are available in different sizes and shapes. We can complete the construction in a short period by using concrete blocks. The cost of concrete blocks are lesser than the conventional bricks, and the strength and durability are also higher. The mix ratio will be differ based on the size of the concrete blocks. The concrete blocks are manufactured by mixing of cement, fine & coarse aggregate with proper water-cement ratio.
