Abstract
Using of plasticizer as added to mixing materials of concrete has affect on proportion of this materials and fresh ,harden properties of it . Research is show that effect through study behavior three mixing with cement content (380,300,210) kg/m3with three plasticizer percents (1,2,3 ) % by weight of cement for each of mix . Then results show that increasing slump in fresh mixture with 18% percent, and increasing with tensile , compressive strength and density with ( 34.93 , 58.82 , 3.5 ) % respectively, and absorption decrease with 30.1% for 380 kg/m3 cement content and 3% plasticizer at 28 days with respect to reference mixture . The research indicates that we can reduce the quantity of influential materials in mixture, such as w/c ratio 20% with using 3% plasticizer . for three different cement content given very expensive properties fresh and harden concrete . In comparison with reference mixture without plasticizer and decrease in cement content 21% with 1% plasticizer given a same properties which is given from without plasticizer with 380 kg/m3 cement content .
