Manufacturer of concrete hollow block and paversSix distinct advantages why you should opt for high quality concrete masonry units (cmu) (precast concrete hollow block)Structural strengthThe excellent manufacturing process of the besser plant (made in u. S. A) produces quality and high strength concrete masonry units. These cmu have a minimum compressive strength of 7n/mm2 (1000psi) and are reliable and predictable under compressive and tensile stresses.EconomyAll cmu for a given size are of exact dimensions and this makes block laying so much easier and faster. Compared to normal bricks, the size of the cmu are about five times larger in surface area, enabling faster completion of work. Because of the high compressive strength, rough handling on site does not easily damage the blocks. Hence, wastage is minimal. Transportation of palletized blocks further reduces breakages. All these help you save in terms of materials, labour, time and costs.Sound insulationDue to the high density and hollow cavities, a cmu wall has excellent sound insulation. These sound insulation properties keep your working and living environment quiet and peaceful, an important consideration in terrace housing, school, apartments and industrial building. (acoustic test peport available upon request)Excellent thermal insulationCmu provide natural thermal insulation due to presence of trapped dead air in the cavities. In the hot tropics a cmu building is cooler and more comfortable than a conventional building. A distinct advantage if cooling installations are required resulting in lower initial installation costs and lower energy consumption. (thermal measurement report available upon request)Fire resistanceCmu offer excellent fire resistance. Cmu is incombustible and could not start or spread a fire. Cmu is rarely damaged by fire, it does not buckle like steel, spall like reinforced concrete or burn like timber. *Other usesCmu are ideal for reinforced masonry structures. Steel reinforcement can be installed in the cavities of the cmu and the same grouted thus enhancing its flexural and tensile resistance. This eliminates the use of shuttering or formwork and the construction period and cost can be further reduced. Some applications of reinforced masonry using cmu are load-bearing walls in non-frame construction are retaining wall structures.
