A Study on the Resisting Behaviour of Different Kinds of Light Concretes and Their Application in Unyielding the Constructions

Light concrete has held such an extensive application in the current construction industry. Light concrete can be an insulator with a suitable resistance and provide an appropriate quality matching with its type of usage . This concrete is made up of cement , fine sand , water and a chemical substance producing foam . The foaming substance can be mixed with water in a special apparatus , in addition , it produces and stabilizes bubbles at a high speed . The final production would be a steady foam which blends with the mortar of cement and fine sand in a particular mixing machinery and forms a flowing paste that can be applied in its normal shape or in metallic or plastic moulds . After , the paste is dried , it gets the spatial weight from 300 to 1600 kg because it contains some percentage of cement and fine sand . According to researches , this current essay categorizes different types of light concretes based on resistance and it also studies the general specifications of light concrete regarding to distinct sorts of the global standards . Pressurized and permanent resistances have been analyzed from the global standards point of view . So , some experiments have been exerted on different kinds of concretes . Conclusively , the main characteristics of light concrete presented and its application in scheming and constructions’ withstanding will be considered as well . Eventually , two main samples of modern light concretes have been introduced regarding to resisting specifications .
