This project is a study of construction of hollow concrete block masonry. The emphasis in the present study is given to study the crack patterns developed in the structural elements like columns constructed with hollow concrete blocks, and to the load carrying capacity of the hollow concrete block individually and when used in the masonry work.
Oct 15, 2014 · Advantages and Disadvantages of Concrete Block Foundations The blocks are placed just like a bricks, in a pattern that overlaps to help interlock them together. This ensures that the foundation is strong and stable. Since the blocks are hollow inside, re-bar is placed inside to connect the blocks to the footing for addition stability.
ADVANTAGES OF HOLLOW CONCRETE BLOCKS. Highly Durable: The good concrete compacted by high pressure and vibration gives substantial strength to the block. Proper curing increase compressive strength of the blocks. Low Maintenance
