In the construction industry, Concrete Masonry Units(CMU) are used to create a concrete block structure such as that of a fence or wall. They’re commonly made of concrete and a collection of specific design combinations that depend on the strength needed. Systems that are used as CMU are naturally non-load bearing and should never be used to carry vertical loads. Moreover, in order to build a CMU or a concrete block, you need to first understand the checklist. The list below contains the commonly used types of concrete blocks in the construction industry.
– Hollow Concrete Blocks
These are among the most used concrete blocks in the industry. Hollow concrete blocks are commonly manufactured by using light aggregates. The aggregates have a specific load design that depends on where it will be made use of. These concrete hollow blocks usually have voids that cover a quarter of the gross area; research suggests that the solid area should never be less than a half of the whole area in order to obtain the maximum allowed load capacity. Typically, the voids are filled by light aggregate mortar material. Concrete hollow blocks are of two types; non-load bearing and load-bearing. They’re also available in different sizes.
– Concrete Bricks
Concrete bricks are made in a small rectangular shape and are piled and arranged in a certain way to build a rigid wall. They’re made of concrete or cooked clay. Solid concrete is used by several manufacturers but others prefer to play around with the aggregates and cement ratio for economic reasons. Others go ahead and create bricks that are of different colors so as to suit the needs of the clients. Usually, concrete bricks are used in facades and fences because they offer an attractive aesthetic appearance.
– Solid Concrete Blocks
When compared to concrete bricks, solid concrete blocks are bigger, heavier and denser. They’re built from naturally dense aggregates and are meant to be strong and heavy. Being strong is the main reason why they are used in large load-bearing masonry units. Also, they are costlier than the concrete bricks since they can resist more forces. Here at EPCD we can provide concrete blocks as height adjusters for all our scaffolding boards, for all your Leeds scaffolding needs.
– Paving Blocks
Typically, paving blocks are just a square or rectangular box that is reinforced with concrete. Usually, they’re used in pavements and roads and for this reason they’re painted with highly noticeable concrete paints to allow easy view from drivers and motorists. Also, these blocks are rigid enough such that they can resist any vehicle collisions. You can also find paving blocks in a walkway, parks or even in parking spots. Usually, their size is 60 mm.
– Lintel Blocks
Lintel blocks are concrete blocks used to prepare for lintel beams. They’re manufactured not only to serve as masonry units, but also as formworks. Lintel blocks have a deep groove which concrete and reinforced bars are placed. This means they permanently work as a lintel beam member’s formwork system. These two functions make them useful, efficient and admired by most builders.
– AAC(Aerated Autoclaved Concrete Block)
They’re larger and lighter compared to bricks. Usually, they’re made of similar ingredients used in making bricks but their’s have a slightly different composition. Research has shown that the use of Aerated Autoclaved Concrete Blocks has significantly reduced the overall consumption of concrete and steel by 10% and 15% respectively. However, bricks have surpassed AAC when it comes to coping with different surfaces, fire resistance, construction time and cost. In order to install the AAC, submission and approval of a method statement is a must before beginning to work.
– Concrete Stretcher Block
They are quite similar to corner blocks and are mainly used to join masonry units. They’re also quite similar to the hollow concrete blocks but when it comes to laying them, they’re done parallel to the wall’s face. Also, they come with these additional reinforcing bars, adhesive material or paste as well as an approved mortar. Moreover, selecting a masonry unit depends on the builder’s preferences; it’s recommended to use a mixture of the masonry unit.
Each masonry unit is manufactured for different uses. It’s recommended to seek suppliers’ guidance since they’re well familiarized with the products. They can offer knowledge an ideas you never knew. Also, engineers can inquire for a demo from the suppliers to assist them in installing their products.
