The cupola slag in the form of fine and coarse aggregates is shown in The mix proportions for M20 and M25 grades are shown in Table 2. The cube and cylinder specimens are casted and cured for 7 days and 28 days. The total number of cubes and cylinders casted are 96 each for both M20 and M25 grades.
Steel industry results in accumulation of steel slag wastes causing severe environmental problems. These wastes can be recycled and replace natural aggregates resulting in sustainable green concrete. In this research, natural aggregates in selfcompacting concrete (SCC) are replaced, wholly or partly, by steel slag coarse aggregates that were produced by crushing byproduct boulders obtained ...
0% to 100% partial replacement of fine aggregate with Energy Optimized Furnace (EOF) Steel Slag with an increment of 10%. Destructive testing method is carried out by crushing of concrete and NDT method is done by Ultrasonic Pulse Velocity (UPV) and Rebound Hammer (RHT) tests. The relationship between the result of the non
selfcompacting concrete (SCC) using Ground Granulated Blast furnace Slag (GGBS) limestone powder as mineral admixtures along with pond ash as substitution of fine aggregate by providing the different percentages of confinement. There is a need to implement SCC for the use of components in order to study the structural behaviour.
replacement of natural sand with steel slag sand, which is yet another waste material lying in steel plants across Karnataka. Objectives: 1. To study the fresh properties and to assess the compressive strength of SCC using egg shell powder (ESP), a waste material, as partial replacement for cement. 2.
The optimum percentage of replacement for fine aggregate (FA) is 40% and for coarse aggregate (CA) is 30%, beyond which the compressive strength decreases on further replacement. It was observed that the partial replacement of fine aggregate by steel slag improves the compressive, tensile and flexural strength of concrete.
Utilization of industrial waste products in the construction industry draws serious attention of many researchers and investigators. In this study an experimental investigation has been carried out to study the significance of blast furnace slag as partial replacement for coarse aggregate in fly ash blended selfcompacting concrete.
increasing the sand content at the cost of the coarse aggregate content by 4% to 5% by weight [2, 3]. But the reduction in aggregate content results in using a high volume of cement which, in turn, leads to a higher temperature rise and an increased cost. An alternative approach consists of incorporating a viscositymodifying
Since the new trends in concrete construction goes towards selfcompacting green concrete, it becomes important to study the possibility and effectiveness of using steel slag aggregate (SSA) in selfcompacting concrete (SCC) as a replacement of coarse aggregate.
possibility of using such steel slag waste materials as coarse aggregate in concrete. In this work, coarse aggregate is partially replaced by steel slag in concrete at different replacement proportions like 10%, 20%, 30% up to 100%. Strength parameters like compressive, split .
2. % increase in the compressive strength was observed for geopolymer concrete with 40% copper slag as replacement for fine aggregate due to high toughness of copper slag. Fig. 2 Compressive Strength Results Split tensile strength. One of the indirect .
The replacement of river sand by slag aggregate provides dual advantage of reducing disposal problems in steel industries and conserving the natural resources. In this study, slag aggregate originated from induction blast furnace has been used.
weights of steel slag aggregate concrete were about 2800 kg/m3. Use of steel slag as coarse aggregate caused more increase in unit weight of concrete, in comparison with use of slag as fine aggregate. Unit weights of concretes containing coarse steel slag were about 2600 kg/m3 whereas unit .
The results show that it is possible to produce SCC using steel slag aggregate. Hence, green sustainable SCC can be produced. The results show that the fresh properties become sensitive for SSA replacement ratios exceeding 50#x0025;.
partial replacement of coarse aggregate with steel slag and fine aggregate by msand in concrete August 11, 2018 ABSTRACT: In this paper, researchers studied and developed waste management strategies to apply for advantages for specific needs.
Hence, partial or full replacement of coarse aggregate by recycled coarse aggregate and partial replacement of fine aggregates by eco sand is researched in this article, in view of consuming the ecological balance. The fresh and hardened properties of SCC using recycled coarse concrete with eco sand were evaluated. SCC mixtures were
aggregate recycled steel slag. The steel slag was added in different mix proportion to partially replace the natural sand. The specimen was tested to find compressive strength, split tensile strength, flexural strength and modulus of elasticity of concrete. The test result indicated the optimum replacement level of fine aggregate with steel slag as 40%.
The density of the GGBFS replaced concrete was found to be minimum compared to the density of BFS replaced concrete. The density of BFS replaced concrete was found to be 2459 kg/m3 for 5% replacement of fine aggregate, and then it starts to increase.
Slag as replacement of normal crushed coarse aggregate and fine aggregate by [15] was found that the compressive strength increased by 4% to 7%. The workability of self compacting concrete with ground granulated blast furnace slag up to 30% replacement is very good [16].
This paper investigates the possibility of utilizing Granulated Blast Furnace Slag (GBFS) as a sand substitute in cement mortar, in order to reduce environmental problems related to aggregate mining and waste disposal. In this investigation, cement mortar mix 1:3 and GBFS at 0, 25, 50, 75 and 100% replacement to natural sand for constant w/c ratio of is considered. The work
possibility of using copper slag as a replacement of sand in concrete mixtures in various percentages ranging from 0%, 20%, 40% 60%, 80% and 100%. It was observed that, the flexural strength of concrete at 28 days is higher than design mix (without replacement) for 40% replacement of fine aggregate by Copper slag. Atul et al
Feb 11, 2017· If you want to replace natural sand on the other hand there are plenty of options available which are now even approved as per IS 383 2016. Crushed Stone: Generally having more fines thus requires fine tuning of mix proportion.
replacement of fine aggregate using steel slag was adopted to be 60 percent. Dolomite based concrete mixture was studied as a reference mixture and the results revealed that the mechanical properties of concrete made with steel slag aggregate are comparable to that of dolomite concrete up to the temperature of 550°C. The

Group two was used to study the same parameters of group one but using 15% crushed glass as coarse aggregate as a partial replacement, in concrete mix instead of natural aggregate. Groups three and four were also used to study the same parameters but using 25% and 35% crushed glass as coarse
