Investigation of Incorporation of two Waste Admixtures Effect on Some Properties of Concrete

Study of the properties of concrete by adding two of the admixtures; iron splinters and minced rubber has been made to explore the concrete behavior with two curing periods 7 and 28 days. It has been taken into consideration in the present study the investigation of their effects on some properties of concrete, such as compressive strength, flexural strength and concrete densities. The admixtures were added in different percentage from cement content as a replacement of aggregates to concrete with mixing ratio of 1:1.5:3. The dry unit weights were decreasing with increasing percentage of the admixtures regarding to the reference concrete especially for admixture ratio of 5and10% for from iron splinter and 5% of minced rubber respectively. It is concluded that the ratio of adding 10% from iron splinter and 5% of minced rubber admixture is supposed to be optimum percentage, that gives the highest compressive strength. This type of concrete which contain industrial wastes could be used in many types of concrete structures such as slabs, partitions, and platforms, as the test shows a significant development in strength of the concrete.
