The selection should be done based on your requirements such as strength and cost. The grade selection is based on applications such as <strong>beams, slabs, columns and foundations<\/strong>. In order to beat out the drawbacks associated with the weak soil, the weight of the building should be assessed properly.<\/p>\n<h2><strong>Low density concrete<\/strong><\/h2>\n<p>The <strong>density of traditional concrete<\/strong> is of the order of 2200 to 2600. The self weight of light weight concrete is in between 300 and 1850 kg\/m3. The dead load will be reduced drastically and the progress of building will be increased. The <strong>hauling and handling cost will be reduced<\/strong>. If you go for frame structure, the beam and column should carry the <strong>load of wall and floor very efficiently<\/strong>. The thermal conductivity of light weight concrete is very low.<\/p>\n<h2><strong>High density concrete<\/strong><\/h2>\n<p>The strength of high density concrete <strong>varies from 3360 kg\/m3 to 3840 kg\/m3<\/strong>. If iron is used as <strong>fine and coarse aggregate<\/strong>, the density will be up to 5820 kg\/m3. Heavy natural aggregates are used in heavyweight concrete. These natural aggregates include barites and magnetite. If barites are used, the density will be around 3,500 kg\/m3. It is possible to use manufactured aggregates as well such as iron or lead shot.<\/p>\n<p>The density is influenced by the type of aggregate. The density of <strong>high density concrete<\/strong> is 45% greater than the normal concrete. It is possible to achieve very heavy strength by going for iron or lead shot and it will be in the range between <strong>5,900 kg\/m3 and 8,900 kg\/m3<\/strong>. The typical applications include construction of <strong>radiation shields and ballasting of pipelines<\/strong>.<\/p>\n<h2><strong>Mass concrete<\/strong><\/h2>\n<p>Strength is the secondary concern when you go for mass concrete. The design will be based on <strong>durability, thermal action and economy<\/strong>. The thermal behavior is the most distinguishing factor of <strong>mass concrete<\/strong> from other types of concrete. Sufficient measures should be taken while dealing with <strong>cracks<\/strong> that arise with<strong>thermal behavior<\/strong>. The structural integrity <strong>should be protected and seepage<\/strong> should be contained.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Different Grades of Concrete There are different grades of concrete in the market.
