Types of Concrete Blocks

Q: Concrete Block Pavement

Concrete blocks, a kind of 8 block, are precast concrete units about the size of a normal house brick. Interlocking concrete block pavement is constructed with individual block being laid in patterns with close, unmortised joints on a bedding sand layer between restraints .

Introduction of Concrete Blocks

Concrete blocks, widely known as Concrete Masonry Unit (CMU), encompass various types of blocks such as solid concrete blocks, hollow concrete blocks, and more These types of concrete blocks have some advantages with compare to brick and stone masonry blocks. This concrete blocks may be solid in shape or hollow

The normal size of concrete block is 39cm x 19cm x (30cm or 20 cm or 10cm) or 2/4/6/8/10/12 inches. Generally cement, aggregate (coarse and fine) and water is used to construct those concrete blocks. 1:6 is the cement-aggregate ratio where 60% is for fine aggregate and 40% is for fine aggregate.

The normal minimum strength of these blocks are 3N/mm2.

1. Solid Concrete Blocks

Solid concrete blocks, one of the different types of concrete blocks, are widely used in construction but they are very heavy in weight because it is manufactured from dense concrete.

This types of bricks are strong in nature and it provides good stability. Solid Concrete blocks are very suitable in load bearing structure and this is highly preferable. Solid concrete blocks are available in many size and this is generally larger than normal clay bricks.

2. Hollow Concrete Blocks

Hollow concrete blocks, representing one of the types of cinder blocks, have more than 25% of gross concrete. This type of blocks are light weight and easy to install in the construction site. Hollow concrete blocks are divided into several components and they are divided into some types, those are

3. Concrete Corner Block

This type of concrete blocks are used in the corner part of concrete masonry. These blocks are widely used in window and door openings. These blocks are laid in the same plane and locked with the other stretcher bond.

4. Concrete Stretcher Block

Concrete stretcher blocks are also used the corner of the masonry. Concrete hollow blocks are widely used in the concrete stretcher block. Concrete stretcher blocks are laid with the parallel length to the face.

5. Jamb Concrete Block

In a building where a elaborated window opening is found then we use jamb concrete block. Stretcher and corner blocks are connected with the Jamb concrete block. In double hung window; jamb concrete blocks are used to provide some space for window members.

6. Partition Concrete Block

Partition are only constructed and used for partition purpose and the height o this type of block is slightly higher than the breadth of the block. These blocks are mainly hollow in nature and this hollow section are divided into two or three parts.

7. Concrete Pillar Blocks

Double corner block is the another name of concrete pillar block. It is generally used where two joints are clearly visible, this only happens in pillar that’s why the name of the block is concrete pillar block.

8. Lintel Blocks

This type of concrete blocks are used for constructing beam or lintel beam, it generally bears the upper portion load of door and window portion. These concrete blocks have a groove portion along with the length of the block. After placing the lintel blocks, it is filled with concrete and reinforcement to increase it’s strength.

9. Bull Nose Concrete Block

Bull nose concrete blocks are also used in the corner portion, the purpose of this type of block is also same. We only use this type of blocks when we want rounded edges at the corner.

10. Frogged Brick Blocks

This type of blocks have a frog portion on top surface of the block along with header and stretcher. Frog helps to hold the mortar and create a strong bond with another brick.

11. Paving Blocks

Paving blocks are generally square or rectangular in size and these blocks are constructed with reinforced cement concrete. Paving blocks are normally laid in the shoulder part of the highway and these are painted with the paint of high visibility to attract the automobile drivers.

These type of blocks are rigid in nature so it increases the probability of road accidents. Paving blocks are also used in the parks, parking area or sometime in the footpath of any road. The general dimension of the paving block is 60 mm.

12. Light Aerated Concrete Blocks

Light aerated concrete blocks are lightweight in nature. These blocks are constructed with Portland cement, aggregates, sand, high quality, etc. So, they are produced using caerated concrete.

13. Cellular Lightweight Concrete Block

Cellular lightweight concrete blocks are also light weight in nature. These type of blocks have good mechanical strength and low thermal conductivity property. Cellular light weight concrete block are made of low density Portland cement which have a large variety with small air bubbles.

14. Fly Ash Blocks

Fly ash blocks are light weight than the clay bricks and they are also economical than those clay bricks. They are generally made from waste materials which are come from combustion of coals in thermal power plant.

15. Concrete Blocks

Concrete blocks, encompassing various block types like types of concrete bricks, are small rectangular symmetric blocks which create a rigid wall. These bricks have greater compressive strength than normal clay bricks and also have less water absorption property tan the clay bricks.

Concrete bricks are generally made of cement, sand, slight amount of fly ash, etc. These type of blocks are generally used in facades, fences due to it’s beautiful and modern aesthetic look.

FAQ

Concrete Blocks

Building and construction concrete block prices are $1 to $4 per block, depending on the size. Standard 8”x8”x16” concrete block prices are $1.25 to $2.50 each. The biggest 12”x8”16” cmu blocks cost $2 to $4 per block.

Concrete Block Column Foundation

Block foundations have good load-bearing strength, but their lateral strength is limited unless the block is fully grouted with rebar (which is rarely done). When walls are tall, pouring is much faster than using block. Block is more labor intensive—especially as the height of the wall increases.

Block and Pier Foundation

A full block foundation consists of concrete block, mortar and reinforcement. The block is laid to form a wall around the perimeter of the home. A “pier and curtain” foundation consists of concrete block, mortar and brick. Concrete block piers are built every 6 to 8 feet providing support for your home.

Concrete Block Pavement

Concrete blocks, a kind of 8 block, are precast concrete units about the size of a normal house brick. Interlocking concrete block pavement is constructed with individual block being laid in patterns with close, unmortised joints on a bedding sand layer between restraints .

Waterproofing Block Foundation

To waterproof, strengthen, and preserve the overall appearance of your basement cinder block walls, seal the blocks permanently against moisture and efflorescence with radon seal plus penetrating concrete sealer.

Concrete Pier Block

Pier blocks can be used instead of footings for a ground-level deck not requiring permits. Any decks higher than 24” require concrete piles 10” in diameter and 48” below grade. These footing size requirements are to ensure enough soil bearing to prevent the joist from sinking in the ground.

Concrete Block Pier Foundation

A “pier and curtain” foundation consists of concrete block, mortar and brick. Concrete block piers are built every 6 to 8 feet providing support for your home. Brick is then placed between the piers to close in the crawlspace. This brick is not load-bearing.

Shipping Container Foundation Blocks

To block container blocking can be helpful in situations where you have uneven ground or it is a low-lying area that can be in a puddle after rains. Blocking will even out a container to make it more level.

Concrete Wall Contractors

Poured concrete walls are not restricted to the same limitations as cinder blocks. On the downside, poured cement walls can be more expensive than block walls when cement prep and production are far from the site. It is something to consider when building a home from scratch.

Concrete Block Slab Foundation

CMU blocks may be reinforced with steel rebar and filled with mortar to create strong foundations. Correctly built and designed, the compressive strength of CMU block walls provide good support for the vertical loads on foundation walls.
