The Use Of Okhra Soil And Nano Aluminum Oxide In The Colorability Of Concrete And The Investigation Of Some Mechanical Properties And Wear Durability Of Concrete

Recently, Colored Concrete Is Used In Many Countries For Aesthetic Purposes. This Made The Gray Color Of Ordinary Concrete Less And The Surroundings More Beautiful. Colored Concrete Is Used In The Construction Of Floors. Colored Concrete Floors Can Be Considered A Better Alternative To Old Floors. Because It Reduces Costs, Reduces Materials And Manpower, Reduces Weight And Reduces Environmental Risks. In This Research, To Make Red Concrete, Okhra Powder Was Used In The Amount Of 2.5%, 5%, 7.5% And 10% By Weight Instead Of Part Of Cement. Also, To Strengthen The Wear Resistance Of Concrete, Nano Aluminum Oxide Powder Was Used In The Amount Of 0.5% By Weight Of Cement. Next, To Reduce The Cost And Ease Of Implementation, A Coating Layer Of Mixed Okhra And Nano-Aluminum Was Used On The Concrete Surface And Its Results Were Compared. The Results Of This Research Showed That Okhra Colored Soil Will Reduce The Wear Durability Of Concrete, But Its Combination With Nano Aluminum Powder Can Significantly Increase The Wear Durability While Maintaining The Quality Of Concrete Color. Also, Creating A Colored Coating Layer On The Surface Of The Concrete Is Less Effective Compared To The Mixed Design, So That The Use Of This Method Can Reduce The Wear Resistance Of Concrete By 40%.
