coarse aggregate in the concrete. concrete tested with varying percentages of rubber from to 15% of normal aggregates. compressive strength, of concrete is measured and comparative analysis is made. introduction during the last three decades, there have been dramatic changes in to coarse aggregates should be reduced. the fine to coarse ratio depends upon the particle shape, surface texture of both fine and coarse particles. the gradation of coarse and fine aggregate is very important. very fine sand is not recommended for concrete purpose. the fines content in the sand below 600 microns should be about toaggregate properties and results are presented in table the concrete mixes were prepared by the same method, which requires using exactly the same aggregate grading curve and concrete composition in terms of cement content, coarse and fine aggregate quantities and slump value. the differences between the various mixes are thus reduced
How Fine Aggregates Afeects Concrete Mix Design
fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete. fineness modulus specifies how much fine aggregate is required in a given mix design. fine aggregate moisture slag is pulverized into a fine powder called ground granulated blast furnace slag and is used in this form as a cementitious component of concrete. fly ash fly ash is the most widely used pozzolan in concrete. It is a fine residue resembling cement that is a by-product of burning coal in an electric power generating plant. depending on thekeywords: copper slag, fine aggregate, concrete, strength, workability, density. introduction aggregates are considered one of the main constituents of concrete since they occupy more than 70% of the concrete matrix. In many countries there is scarcity of natural aggregates that are suitable for construction whereas in other
