研究添加两种外加剂的混凝土性能；制作了铁碎片和碎橡胶，以探索混凝土在 7 天和 28 天两个养护期的性能。本研究已考虑研究它们对混凝土某些性能的影响，例如抗压强度、抗弯强度和混凝土密度。外加剂按水泥用量的不同比例添加，代替骨料加入混凝土中，配合比为1：1.5：3。相对于参考混凝土，干单位重量随着外加剂百分比的增加而降低，特别是对于铁碎片和5%碎橡胶的外加剂比例分别为5%和10%。结果表明，铁片添加量为10%，橡胶碎料添加量为5%，是获得最高抗压强度的最佳比例。这种含有工业废料的混凝土可用于多种类型的混凝土结构，如板、隔墙和平台，测试表明混凝土强度显着提高。
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.
