Bricks and blocks are masonry units and are referred to as such in SABS standards. Units may be solid or hollow. The difference between bricks and blocks is one of size. In this pamphlet "block" is used throughout, but the same principles apply to brick. 2. feasibility study It is easy to make a concrete block. The successful blockyard
PROJECT ON HOLLOW BRICKS ... Hollow concrete blocks are substitutes for conventional bricks and stones in building construction. They are lighter than bricks, easier to place and also confer economies in foundation cost and consumption of cement. In comparison to conventional bricks, they offer the advantages of uniform quality, faster speed of ...
In hollow bricks manufacturing raw materials are cement, stone chips 0.5″, sand and stone dust. Moreover, you can procure the raw material from the nearby districts and from other states. Ordinary Portland cement is the cementing material used in cement concrete hollow blocks.

Concrete Blocks Technical Data Short Description Concrete block construction has gained importance and has become a valid alternative to fired clay bricks. The essential ingredients of concrete are cement, aggregate (sand, gravel) and water. Concrete blocks are produced in a large variety of shapes and sizes. They can be produced
This paper reports a tentative analysis to correlate the mechani-cal behavior of cylindrical concrete samples to the structural be-havior of hollow concrete blocks. Instead of analyzing blocks with unknown concrete properties, plastic consistency concrete was used to mould hollow blocks and test samples to assure the same
Introduction These are the concrete blocks either hollow or solid. A hollow unit is that unit which has core void area greater than 25% of the gross area. They may be used for both load bearing as well as non load bearing walls.
800000 Nos. of cement concrete hollow blocks of size 100X200X400 mm. At 75% utilisation of the capacity, productions of 600000 Nos. of blocks have been taken into consideration. Cement concrete hollow blocks are usually of the following three dimensions: 100X200X400 mm, 150X200X400 mm and 200X200X400 mm. Although
load carrying capacity of the hollow concrete block individually and when used in the masonry work, by comparing the work with brick masonry this will help builders to appreciate the essential constructional details and adopt hollow concrete block masonry in a large scale wherever it is economical.
These concrete hollow blocks are more useful due to its lightweight and the most important feature is ease of ventilation. The concrete hollow blocks are made out of mixture of cement, sand and stone chips. It reduces cement in masonry work and reduced the cost of construction. The hollow concrete blocks found out due to different
