·concrete in construction structural material consisting of a hard chemically inert particulate substance known as aggregate usually sand and gravel that is bonded together by cement and Among the ancient Assyrians and Babylonians the bonding substance most often used was clay The Egyptians developed a substance more closely resembling modern
Instead cement is an ingredient used to make concrete Cement is made from limestone and clay It s the paste that binds with the other ingredients to hold the concrete together To make concrete you need air water cement and aggregates Concrete contains fine aggregates like sand and coarse aggregates like rocks Makers of concrete
6 ·Lightweight Concrete Lightweight concrete is made by using lightweight aggregates such as expanded clay or shale to reduce the density of the material It is commonly used in situations where weight reduction is crucial Limecrete In this type of concrete cement is replaced by lime Limecrete is used in floors vaults and domes
·The Portland cement is made of iron ore limestone and clay and binds all the ingredients together in our fibre cement products The sand in the mix creates weather resilience and performance And last but not least water is needed to dissolve the wood pulp into cellulose fibres making the mixture strong but flexible and to activate and
·cement in general adhesive substances of all kinds but in a narrower sense the binding materials used in building and civil engineering construction Cements of this kind are finely ground powders that when mixed with water set to a hard and hardening result from hydration which is a chemical combination of the cement compounds with water
·As concrete is made from fewer materials it is an economical and effective choice Moreover the proportions of these ingredients vary depending on the specific construction purpose Composition of Basic Concrete Mix The materials of concrete mix play a crucial role together in giving enhanced strength and desired properties The proportions
