Replacement Of Sand In Concrete With Slag And Mill Scale

mill scale as an additive for cement use – mill scale,mill scale contains iron oxides that can be substituted for other iron-bearing materials when used in the kiln feed. select types of slag can produce a blended cement product when inter-ground with portland cement. as a replacement for natural stone as an aggregate, foundry sand and some types of slag can be used in portland cement concrete..

Effect of Partial and Total Replacement of Fine Aggregate

Effect Of Partial And Total Replacement Of Fine Aggregate

concrete with partial and total replacement of conventional sand with mill scale and the study is made with systematic approach with sequential steps. a conventional m20 grade cement is prepared. in the mix sand replacement by weight of 0%, 20%, 40%, 60%, 80% and 100% with mill scale was considered. concrete with these six,(pdf) characterization of mill scale for potential,it is seen that the specific gravity of mill scale is 4.96, which is nearly two times that of sand (typical values being 2.65). this means that if mill scale is used as partial replacement of fine aggregates in concrete it would result in denser concrete and hence can be used in high density concreting.

with steel slag and mill scale aggregates. for this research the percentage of the volume of natural aggregates normally used in concrete was partial replaced by steelslag and millscale .this replacement was done in 25% increments until all natural aggregates were replaced by the steel slag and millscale .thus replacing the,properties of high density concrete with mill scale waste,this study concentrates on the utilization of mill scale waste for the production of ballasts used in washing machines. ballasts act as counterweights in washing machines and require a standard weight. thus, high density concrete is used to produce ballasts occupying lesser volume for the given weight. mill scale acts as a high density aggregate and is used as a complete replacement of fine and



has concluded that 40% replacement of sand with steel mill scale gave the highest increase in compressive strength. li yun feng (2009) found that concrete with good performance can be produced using mineral admixtures consisting of steel slag powder and blast furnace slag. in the present paper an experimental investigation on the mechanical properties of concrete has been made with 0% to 20%,(pdf) utilization of industrial waste slag as aggregate in,the partial substitution of natural aggregate with slag aggregates permits a gain of strength at long term but entire substitution of natural aggregates affects negatively the strength (a loss in strength of 38%).saud al-otaibi, 2008 [8] studied use of recycling steel mill as fine aggregate in cement mortars. the replacement of 40% steel mill scale with that of fine aggregate increased compressive strength by



slag is observed to increase upto replacement level of 40%. (3) concrete made by using 40% partial replacement of slag shows the strength improvements that vary from around 6 to 20%. finally, it can be concluded that, slag from bangladesh steel re-rolling mills (bsrm) can be used as,engineering behaviour of sustainable concrete with steel,it was found that very small particle size of steel mill scale fills the voids between the fine and coarse aggregate thus makes dense concrete. the test outcomes suggest that recycling steel mill scale by utilizing as a fractional replacement for fine aggregate offers a viable cost effective and environmentally friendly solution at 60% replacement.
