![]() ![]() Here, we will demonstrate easy step by step process to calculate the concrete blocks used for civil construction. Calculation of Concrete BlocksĬalculating the quantity of blocks needed for a building is a straightforward process that does not require any previous building or architectural skills. This is then heated before being mixed with cement, lime and a small amount of aluminium sulphate powder. PFA is mixed with sand and water to form a slurry. The blocks are made from cement, lime, sand, pulverised fuel ash (PFA) and water. ![]() The shape and texture can directly affect its workability. The shape of the lightweight aggregate used in concrete can be cubical, rounded, angular, or of any other shape. The lightweight aggregate is a kind of coarse aggregate which is used in the production of lightweight concrete products like concrete block, structural concrete, and pavement. These blocks are used for internal and external loadbearing walls, including walls below ground. These blocks are as heavy per cubic metre as bricks, they are not good thermal insulators and their strength in resisting crushing is less than that of most well burned bricks. The usual mix is 1 part of cement to 6 or 8 of aggregate by volume. ![]() The blocks are made of Portland cement, natural aggregate or blastfurnace slag. There are mainly three types of Concrete Block: Concrete blocks? advantageous properties are reflected in their myriad of variations of strength, insulating and sound-reducing properties. Today, the immense versatility of concrete blocks is demonstrated in their use throughout a building from its foundation walls, through cavity walls, monolithic walls, partition walls, separating walls and as a component of ?beam and block? flooring. The mix, cast in wooden moulds, consisted of powdered limestone and clay mixed with water. In 1827, Joseph Aspidin devised the basic mix that we would still recognise today. History of Concrete Blocks: Though history records the use of concrete blocks by the Romans, Greeks and even Egyptians (some of the two-tonne blocks that make up the Pyramids are believed to be a primitive form of concrete), modern-type blocks were first cast, albeit in modest quantities, in around the middle of the nineteenth century. ![]()
