Ppt On Slag Replacing Natural Aggregates. Making slags as substitutes for natural aggregates can be expected because it has constant quality and is characterized by the capability of a stabilized and massive, because the specific weight of a steelmaking slag is larger than that of natural aggregates, there is a possibility of massive production at a lower cost of.
Replacing all or some portion of natural aggregates with steel slag would lead to considerable environmental benefits. Steel slag is currently used as aggregate in hot mix asphalt surface applications, but there is a need for some additional work to determine the feasibility of utilizing this industrial byproduct more wisely as a replacement for both fine and coarse aggregates in a
various replacement level of steel slag with fine aggregate. The use of steel slag aggregates in concrete by replacing natural aggregates is a most promising concept. Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance. II. MATERIALS USED
when compound mineral admixtures with steel slag powder and blast furnace slag powder mixed in concrete. Lun Yunxia, Zhou Mingkai, Cai Xiao, Xu Fang, 2008 [6] used steel slag as fine aggregate for enhancing the volume stability of mortar. Experimental results indi cated that powder ratio, content of free lime and rate of
Steel Slag As A Partial Replacement In Fine Aggregate. Steel Slag As A Partial Replacement In Fine Aggregate. The experimental program was designed to study the mechanical properties of concrete with partial replacement of fine aggregate by steel slag for m 20 grade of compressive, tensile and flexural strength of the specimens after replacing the fine aggregates by 10%, 20%, 30%
Aug 2, 2012 In this study, steel slag was used as an aggregate replacement in conventional dense graded asphalt mixes (ACW14 and ACB28). Steel slag was selected due to its characteristics, which are almost similar to conventional aggregates, and the fact that it is easily obtainable as a byproduct of the steel
aggregates in a conventional concrete mixture. This paper present results of experimental investigations carried out to evaluate effects of replacing aggregate (coarse and fine) with that of slag on various concrete properties. In this study, concrete of M20 and M30 grades were considered for a replacements of 0, 25%, 35%. 45%, 55%, 65% and 75% of
Steel Slag Aggregates Slag is a coproduct of the iron and steel making process. The use of steel slag aggregates in concrete by replacing natural aggregates is a most promising concept. Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance
Steel slag aggregates are fairly angular, roughly cubical pieces with a flat or elongated shape (as shown in Figure [49]). Replacing some or all natural aggregates with steel slag is helpful for reducing environmental pollution and the consumption of resources [47,48].
whereas large steel slag deposits are locally available. The primary aim of this research was to evaluate the durability of concrete made with steel slag aggregates. This research has shown that replacing some percentage of natural aggregates by steel slag aggregates causes negligible degradation in
Steel slag as a partial replacement in fine aggregate. Portland Cement 53 grade fine aggregate coarse aggregate and steel slag for checking their suitabilities for making concrete Mix proportions of concrete are modified for using EAF steel slag with partial replacement of coarse aggregate replaced with 0 25 50 75 and 100 of steel slag
GGBFSFA geopolymer concrete with steel slag coarse aggregates are prepared by replacing natural granite aggregates at different replacement levels 0%, 25%, 50%, 75% and (by volume) and
So these steel slag aggregates can be used to replace natural aggregates. The crushing value of the steel slag aggregate is found to be %. The CBR value of the steel slag aggregates is found to be % and % for soaked and unsoaked conditions, respectively. The impact value of steel slag aggregates is found to be %.
Steel slag was found to be the best replacement for natural aggregates of concrete. Steel slag which is produced as a waste material in the steel industry and has a negative impact on environment when disposed. In the course of future project work by the replacement of steel slag for the coarse aggregate in concrete of 25%, 50%, 75% with
aggregates. Replacing all or some portion of natural aggregates with steel slag would lead to considerable environmental benefits. This report showcases important studies conducted on use of steel slag as fine aggregate and its effect on the strength, durability, fresh density, workability etc of
Steelslag is a byproduct of the steel industry, and is reported to exhibit great potential as a replacement for natural aggregates in road construction. Steelslag is a waste material that can be recycled as a road construction material. Steelslag aggregates have been reported to retain heat considerably longer than natural aggregates.
