Research On The Application Of Oil Shale Waste Slag Fine Powder In Cement Concrete

Oil shale is one of the most important unconventional oil and gas sources which has a broad prospect of development and application.However,the oil shale industry will produce a large amount of oil shale waste residue,mainly oil shale semi-coke,power plant slag and power plant ash.Because there is no efficient way to utilize oil shale waste residue,a large amount of oil shale waste residue accumulates in landfills,which not only encroaches on agricultural and forest land,but also has the potential risk of polluting nearby soil and water source.If the oil shale waste volcano activity by using it in a reasonable way,used in cement concrete materials,not only can use a lot of oil shale waste,effectively alleviate the waste accumulation environment and space pressure,but also can save the cement material,the resources of oil shale residue,creating considerable economic and social benefits.Based on the above reasons,this paper carried out the research on the application of oil shale residue in cement concrete,the main research work is as follows:1.Analysis of physical and chemical properties of different types of oil shale waste slag.2.Study on the performance and reasonable content of oil shale waste slag fine powder used in cement mortar.3.Experimental study on the compatibility of oil shale waste slag fine powder as cement admixture with concrete admixture.4.Study on performance and reasonable content of oil shale waste slag used in cement concrete.
