Generally speaking, there are two kinds of concrete block, hollow and solid. Hollow Blocks. Hollow concrete blocks have one or more hollow cores. These cores reduce the total cross-sectional area of the block by at least 25 percent. In general, a hollow-core concrete block is more than 50 percent solid. Standard hollow concrete blocks come in full and half sizes. Full-size blocks are rectangular and have two cores.
Studies show that hollow bricks or blocks have greater advantages than the solid bricks. Both clay hollow bricks and concrete hollow bricks have enough proven benefits but the former having much more than the later.
block”, “cinder block”, “CMU”, or simply “block”. Related concrete products, manufactured using similar materials and production methods but used in different applications, include products such as concrete pavers, segmental retaining wall units, and articulating concrete block.
1000 kg/m 3 blocks having this density are typically referred to as Light Weight The actual block densities for Light Weight Vertical Hollow blocks vary from 650kg/m 3 to 800kg/m 3, subject to block thickness; 550 kg/m 3 blocks with this density are typically referred to as Autoclaved Aerated Concrete (AAC) blocks. These blocks are manufactured as solid and for this reason their block density is the same as the material one.
Difference between Autoclaved Aerated Concrete Blocks and Clay Bricks Light Weight Autoclaved aerated concrete blocks volume-weight usually is400kg/m3~700kg/m3, which isequal ofhollow clay bricks ’one third, solid clay bricks ’one fifth, concrete ’s
The solid concrete Blocks resists average earthquake forces because the density of Concrete Block is higher than AAC Block. Earthquake forces are proportional to the weight of the building. AAC Blocks reduce the weight of building so it increases the safety against earthquake.
3.1 Block — A concrete masonry unit, either hollow (open or closed cavity), or solid (other than units used for bonding, such as a half block), any one of the
First produced in Sweden in 1923 and used in the UK since the 1960s (when they were known as ‘cellular’ or ‘gas’ concrete blocks), aerated concrete or ‘aircrete’ blocks are the lightest of the family of concrete blocks. Aerated blocks are distinguished by their capacity to perform a dual structural / insulation function.
hollow block masonry. Only semi-skilled labour is required for this type of construction. It is a faster and easier construction system, when compared to the other conventional
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, 10 inch and 12-inch unit configurations.
Containing proportionately less concrete, a hollow block is lighter than a corresponding cellular block or solid concrete block. Solid concrete blocks. A solid concrete block is a more straightforward concrete masonry unit, in terms of design, being essentially a concrete cuboid. Naturally, the additional concrete in a solid block means greater weight than a corresponding cellular or hollow block.
know the composition, weight, size differences between bricks and blocks. Learn how many bricks and blocks are required to construct a wall of one square meter.
Hollow concrete blocks are lighter than plain concrete blocks (easier to transport and to install) and provide better thermal insulation. They can also be designed to receive reinforcement and concrete as lintels or stiffeners without any additional formwork.
Concrete Solid Block Clay Hollow Block AAC Light Weight Block; Also Known as: Red bricks, Chamber bricks, Table mould bricks, Clay wire cut bricks: Cement blocks, concrete blocks, masonry blocks: Porotherm blocks: AAC blocks, Autoclaved aerated concrete blocks: Composition: Soil, Sand, Lime or other concrete materials. M Sand, Cement and Coarse Aggregates.
Cellular blocks. According to The Concrete Block Association, a cellular block is designed with one or more hollows, or voids. However, these do not go all the way through the block. In most cases, where the plane of the voids is vertical, this means that one of the surfaces to which mortar is applied is voided while the other is whole.
Conventional 8 inch concrete block walls have an R-value of 0.08 per square inch, or about 2.5 for the whole block. Insulated concrete blocks can increase their R-value to about 1.2 per square inch, and air-entrained blocks can have R-values as high as 3.9.
The uniform shape requires very thin mortar layer between blocks, the joinery mortar is as alll know is a fairly costly material being 1:4 mix of cement and sand. The even surfaced wall also requires very thin plaster on both sides which is also a very cement intensive material and thus lot of cost saving is done.
Concrete and cinder blocks share some basic elements, but a key ingredient makes all the difference. People sometimes use the terms interchangeably, but concrete and cinder blocks are very different.Concrete is a product made of cement and aggregates.
