The Use Of Aluminum Oxide Nanoparticles In Improving Some Mechanical Properties And Increasing The Abrasion Resistance Of Concrete
Today, With The Development Of Nanotechnology, The Application Of This Material Is Very Important In Achieving Some Desired Properties In Construction Materials, Especially Concrete. In This Regard, The Use Of Nano Aluminum Oxide Can Cause Changes In Some Physical Characteristics And Mechanical Properties Of Concrete. Due To The High Hardness Of Aluminum, It Is Expected To Increase The Abrasion Resistance Of Concrete With The Help Of This Nanoscale Material. In This Research, By Examining The Effect Of Nano Aluminum Oxide On The Characteristics Of Concrete, While Optimizing The Amount Of Use Of These Materials, The Possibility Of Using Them In Special Applications, Especially Concrete Coatings And Flooring, Has Been Evaluated. The Amounts Of Nano Oxide Aluminum Used In The Concrete Mixing Plan Of This Research, In Weight Ratios Of 0.25, 0.5 And 0.75%, Replace Part Of Cement. Also, With The Aim Of Reducing The Cost And Making It Easier To Implement, The Spraying Of A Diluted Nano-Aluminum Oxide Solution In One To Four Layers On The Concrete Surface Was Also Tested. The Results Of This Research Showed That The Addition Of 0.5% Aluminum Oxide Nano Powder In Concrete Can Increase The Abrasion Resistance Of Concrete Up To 77% While Partially Improving Some Of The Tested Mechanical Properties. Also, The Results Of The Abrasion Test Showed That Creating A Layer Of Nano-Aluminum Oxide On The Surface Of The Concrete, Despite The Improvement Of Effectiveness By Increasing The Number Of Coating Layers, Is Less Effective Compared To The Mixed Design.
