Different Types Of Concrete Blocks Or Concrete Masonry Units Utilized In Construction

Concrete block masonry which generally known as concrete masonry unit (CMU) have advantages over brick and stone masonry. 
Concrete blocks are manufactured in required shape and sizes which might be solid or hollow blocks. 
The common size concrete blocks is 39cm x 19cm x (30cm or 20 cm or 10cm) or 2 inch, 4 inch, 6 inch, 8 inch, 10 inch and 12-inch unit configurations. 
Cement, aggregate, water can be used to arrange 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 approximately 3N/mm2. ASTM C-90-91 specifies the compressive strength requirements of concrete masonry units. 
Varieties of Concrete Blocks or Concrete Masonry Units 
Depending upon the dwelling, shape, size and manufacturing processes concrete blocks are mainly classified into 2 types and they're: 
Solid concrete blocks 
Hollow concrete Blocks 
Solid Concrete Blocks 
Solid concrete blocks are normally used, that happen to be heavy in weight and manufactured from dense aggregate. These are strong and provides good stability for the structures. So for large work of masonry like for load bearing walls these solid blocks are preferable. They come in large sizes in comparison to bricks. So, it will require a shorter period to develop concrete masonry than brick masonry. 
Hollow Concrete Blocks 
Hollow concrete blocks contains void area greater than 25% of gross area. Solid area of hollow bricks ought to be over 50%. The hollow part could be separated into several components based on our requirement. They are manufactured from lightweight aggregates. They are light-weight blocks and easy to set up. 
Kinds 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 employed with the ends or corners of masonry. The ends might be door or window openings etc. they are arranged in a manner that their plane end visible to the outside as well as other end is locked together with the stretcher block. 
Concrete Corner Blocks 
Corner blocks are widely-used on the ends or corners of masonry. The ends could possibly be door or window openings etc. they're arranged in a way that their plane end visible external along with other end is locked with all the stretcher block. 
Concrete Pillar Blocks 
Pillar block can be referred to as double corner block. Generally these are used when two ends with the corner are visible. In case of piers or pillars these blocks are traditionally used. 
Jamb Concrete Blocks 
Jamb blocks are widely-used should there be an elaborated window opening in the wall. They're connected to stretcher and corner blocks. For your provision of double hung windows, jamb blocks are extremely helpful to provide space for your casing members of window. 
Partition Concrete Block 
Partition concrete blocks are usually used to build partition walls. Partition blocks have larger height than its breadth. Hollow part is split into two to three components in the case of partition blocks. 
Lintel Blocks 
Lintel block or beam block can be used when it comes to provision of beam or lintel beam. Lintel beam is mostly provided in the top area of windows and doors, which bears the burden via top. Concrete lintel blocks have deep groove across the length of block as shown in figure. After placing the blocks, this groove is loaded with concrete along with reinforcement. 
Frogged Brick Blocks 
Frogged brick block has a frog on its top as well as header and stretcher like frogged brick. This frog will helps the block to support mortar also to enjoy the strong bond with top laying block. 
Bullnose Concrete Block 
Bullnose blocks are like corner blocks. Their duties also same but when we want rounded edges at corner bullnose bricks are preferred.
