Concrete lintel blocks have deep groove along the length of block as shown in figure. Lintel beam is generally provided on the top portion of doors and windows, which bears the load coming from top. Lintel block or beam block is used for the purpose of provision of beam or lintel beam. Hollow part is divided into two to three components in case of partition blocks. Partition blocks have larger height than its breadth. Partition concrete blocks are generally used to build partition walls. For the provision of double hung windows, jamb blocks are very useful to provide space for the casing members of window. They are connected to stretcher and corner blocks. Jamb blocks are used when there is an elaborated window opening in the wall. In case of piers or pillars these blocks are widely used. Generally these are used when two ends of the corner are visible. Pillar block is also called as double corner block. they are arranged in a manner that their plane end visible to the outside and other end is locked with the stretcher block. The ends may be window or door openings etc. They are laid with their length parallel to the face of the wall.Ĭorner blocks are used at the ends or corners of masonry. Stretcher blocks are widely used concrete hollow blocks in construction. They are light weight blocks and easy to install.Ĭoncrete stretcher blocks are used to join the corner in the masonry. They are manufactured from lightweight aggregates. The hollow part may be divided into several components based on our requirement. Solid area of hollow bricks should be more than 50%. Hollow concrete blocks contains void area greater than 25% of gross area. So, it takes less time to construct concrete masonry than brick masonry. They are available in large sizes compared to bricks. So for large work of masonry like for load bearing walls these solid blocks are preferable. They are very strong and provides good stability to the structures. Solid Concrete Blocks Solid concrete blocks are commonly used, which are heavy in weight and manufactured from dense aggregate. Types of Concrete Blocks or Concrete Masonry Unitsĭepending upon the structure, shape, size and manufacturing processes concrete blocks are mainly classified into 2 types and they are Types of Concrete Blocks or Concrete Masonry Units.
