Kinds Of Concrete Blocks Or Concrete Masonry Items Utilized In Building Construction
Concrete block masonry also is known as concrete masonry unit (CMU) have advantages over brick and stone masonry.
Concrete blocks are made in required shape and sizes which may be solid or hollow blocks.
The most popular size of concrete blocks is 39cm x 19cm x (30cm or 20 cm or 10cm) or 2 inch, 4 inch, 6 inch, 8 inch, Ten inch and 12-inch unit configurations.
Cement, aggregate, water is utilized to organize concrete blocks.
The cement-aggregate ratio in concrete blocks is 1:6. Aggregate used is of 60% fine aggregate and 40% coarse aggregate.
Their Minimum strength is about 3N/mm2. ASTM C-90-91 specifies the compressive strength requirements of concrete masonry units.
Types of Concrete Blocks or Concrete Masonry Units
Depending upon the structure, shape, size and manufacturing processes concrete blocks mostly are classified into 2 types plus they are:
Solid concrete blocks
Hollow concrete Blocks
Solid Concrete Blocks
Solid concrete blocks can be used, which can be heavy in weight and constructed from dense aggregate. They're strong and gives good stability for the structures. So for giant work of masonry like for load bearing walls these solid blocks are preferable. These come in large sizes in comparison with bricks. So, it will take much less time to make concrete masonry than brick masonry.

Hollow Concrete Blocks
Hollow concrete blocks contains void area in excess of 25% of gross area. Solid part of hollow bricks must be a lot more than 50%. The hollow part may be split up into several components depending on our requirement. They're manufactured from lightweight aggregates. They're lightweight blocks and easy to put in.
Varieties of Hollow Concrete Blocks:
Stretcher block
Corner block
Pillar block
Jamb block
Partition block
Lintel block
Frogged brick block
Bullnose block
Concrete Stretcher Blocks
Corner blocks are utilized with the ends or corners of masonry. The ends may be door or window openings etc. they are arranged in ways that their plane end visible external as well as other end is locked with the stretcher block.
Concrete Corner Blocks
Corner blocks are used with the ends or corners of masonry. The ends might be door or window openings etc. they may be arranged in a manner that their plane end visible to the outside and also other end is locked using the stretcher block.
Concrete Pillar Blocks
Pillar block is additionally known as double corner block. Generally they're used when two ends from the corner are visible. In the event of piers or pillars these blocks are traditionally used.
amb Concrete Blocks
Jamb blocks are used should there be an elaborated window opening from the wall. They're attached to stretcher and corner blocks. To the provision of double hung windows, jamb blocks have become necessary to provide space for the casing folks window.
Partition Concrete Block
Partition concrete blocks are often utilized to build partition walls. Partition blocks have larger height than its breadth. Hollow part is split into 2-3 components in case there is partition blocks.
Lintel Blocks
Lintel block or beam block is used with regards to provision of beam or lintel beam. Lintel beam is generally provided at the top percentage of windows and doors, which bears the stress coming from top. Concrete lintel blocks have deep groove along the period of block as shown in figure. After placing the blocks, this groove is loaded with concrete together with reinforcement.
Frogged Brick Blocks
Frogged brick block contains a frog on its top together with header and stretcher like frogged brick. This frog will helps the block to hold mortar and to enjoy the strong bond with top laying block.
Bullnose Concrete Block
Bullnose blocks act like corner blocks. Their duties also same however when we'd like rounded edges at corner bullnose bricks are preferred.
