Özet:

In this research the ability of using porcelinite as coarse aggregate to produce light weight concrete was investigated. The experimental program consists of preparing and testing a mixes to investigate mechanical properties of concrete, with a total of 15 cubes (100×100×100) mm, 30 cylinders (100×200) mm. The tests include compressive strength, splitting tensile strength, fresh and hardened density of light weight concrete for different porcelinite percentages ranged between(0% to 100%) of the coarse aggregate weight. The obtained results for tested specimens were compared to control one. Test results indicated that using of porcelinite in concrete mix reduces the strength of concrete Porcelinite aggregate represents a reduction in density ranging between (10%-36%) of normal weight concrete, therefore there is an advantage using this type of light weight aggregate in this country where soil bearing capacity is low in most construction sites.
