🕑 Reading time: 1 minute Concrete block masonry which is also known as concrete masonry unit (CMU) have advantages over brick and stone masonry. Concrete blocks are manufactured in required shape and sizes and these may be solid or hollow blocks. The common size of concrete blocks is 39cm x 19cm x (30cm or 20 cm or 10cm) or 2 inch, 4 inch, 6 inch, 8 inch, …

Cost. Solid concrete block costs Rs 20 – 40 per piece. Hollow concrete block costs Rs 50 - 90 per piece. Aerated concrete block cost Rs 40 -70 per piece. Brick cost about Rs 4 to 20 per Piece depending on the quality of brick desired. Exposed brickwork needs bricks with fine cut edges and good quality and is expensive comparatively.

Concrete mix for concrete blocks should not be richer than one part of the cement to six parts of the volume of combined aggregate. Concrete blocks can be handmade and also machine-made. The cast block is then cured in a water tank or yard for at least 14 days (water need to be changed at least every 4 days) .

Concrete blocks - sand - cement blocks. Contents - Previous - Next. It is faster to build with concrete blocks than with bricks and the amount of mortar is reduced to less than half. If face shell bedding is used, in which the mortar is placed only along the edges of the blocks, the consumption of mortar is reduced by a further 50%.

4kg of fly ash, cement and sand making up the remainder. The bricks were cured under water for 28 days and baked at temperature ranging from 90oC to 110oC for 2 hours. The key characteristics of these bricks are found to be lightweight, porous, of low thermal conductivity, and of appreciable mechanical strengths.

The use of concrete blocks as a masonry unit can be observed on many construction sites because of the following advantages: It increases the carpet area of the building because of small width of concrete block as compared to the brick masonry wall. It provides better thermal insulation, enhanced fire resistance and sound absorption.

The sand must be 5cm to 10cm thick. Spread the cement over the sand and add aggregates. Use a shovel to mix the sand and cement until a uniform colour is achieved. Sprinkle water over the surface of the mixture. Continue to mix until the correct consistency of concrete is reached.

Concrete block, sometimes called cement brick (or cement stock brick) are widely used as building material. Automatic or semi-automatic machines are available for making concrete block, but it is possible to make them in the free available space of your home.

What is Concrete Hollow Blocks? A Concrete masonry unit (CMU) – also called Concrete block, cement block, and foundation block – is a large rectangular brick used in construction. Concrete blocks are made from cast concrete, example: Portland cement and aggregate, usually sand and fine gravel for high-density blocks.

Solid concrete blocks :- 1500 to 2000kg/m3 Hollow concrete blocks:- 1000 to 1500kg/m3 Compressive Strength: Solid concrete blocks :- >5 N/mm2 Hollow concrete blocks:- >2 to 4 N/mm2 Water Absorption:- <10 to 15% by weight

Concrete bricks are systematically piled blocks that are rectangular in shape and primarily used to build rigid walls. Normally made of concrete or cooked clay, this brick masonry is ideal for building fences, giving them a slick and aesthetic look.While some manufacturers use cement and lightweight aggregate or aggregates to make these blocks, others stick to solid concrete.

Producing concrete blocks is not a very difficult job. There are different ways to produce them: Manually with simple molds or with a machine. Of course, the machine is more preferred because it helps to handle the job easier and faster. We will explain the concrete block manufacturing process details in this article.

The most common use for Portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element. Portland cement may be grey or ...

manufacture concrete blocks as well as paver blocks of various grades. Concrete blocks up to M15 grade and paver blocks up to M50 grade can be manufactured. They apply extreme vibrations to blocks and therefore are able to make concrete blocks at lower w/c ratio resulting in lower binder content as compared to any other machines.
