![]() Construction with a concrete block is more systematic, faster, and stronger, as compared to brick masonry due to the large size of blocks. The difference between a concrete block and a brick is that a brick is a solid or hollow manufactured masonry unit made of concrete, clay, or stone, comparable to a concrete block that comes in hollow or solid formats but is exponentially larger, made of concrete, and are used mainly in load-bearing walls where strength is key. Concrete blocks protect the interiors of a structure against noise pollution, provide better thermal insulation, gives added protection against fire, and cuts down on plaster usage as an economically viable alternative to conventional bricks. Alternatively, book an appointment with an expert.Concrete blocks also referred to as concrete masonry units (CMUs) or cinder blocks are rectangular-shaped blocks used within the construction of walls as a primary building material.

Lightweight concrete blocks can be essential to the structural integrity of a project therefore, it’s extremely important to choose the correct one. For your other projects, we have a comprehensive range of concrete blocks available, including coursing blocks and aerated concrete blocks. If you're looking for lightweight concrete blocks, we work closely with leading manufacturers such as Plasmor, Forterra, and Cemex to provide a wide range of high-quality lightweight blocks, with our range of blocks coming in various dimensions, such as 440x100x215mm, 300x275x140mm, and 300x250x140mm to ensure that you can find the correct size and strength of product for your project. The density of the aggregate used is generally proportional to the strength of the block, for example, super-lightweight aggregates like expanded clay and pumice used for their excellent thermal performance, feature a relatively low compressive strength. ![]() Lightweight concrete blocks are manufactured from cement, mixed with one of a variety of natural or man-made expanded aggregates such as granulated or foamed blast-furnace slag, expanded clay or shale, furnace bottom ash (FBA), pulverised fuel ash (PFA), or the less common pumice (that is a volcanic material). The lightweight block enables time and material cost savings through easier handling than larger units or a different block type with the same dimensions. The main advantage of lightweight concrete blocks over dense aggregate blocks is a combination of higher insulating properties and a lighter block unit weight. Lightweight concrete blocks are used in both internal and external walls where loading is slightly more restricted, or as infill blocks in beam and block flooring. Lightweight blocks are produced in greater volume but are less strong than dense concrete blocks. Lightweight concrete blocks can be used in external applications as well as a versatile range of internal applications. Lightweight blocks are also manufactured with lightweight aggregates for a lighter more manageable concrete block. Lightweight concrete blocks are high-level performance in load-bearing and other structural applications. Lightweight concrete blocks are ideal for commercial and leisure developments, providing an even surface for paint and other finishes, with excellent resistance to air permeability.
