(GGBS) in cement concrete as a sand substitute, for reducing the environmental problems related to the fine aggregate mining and waste disposal of slag. The percentage of GGBS replacement is 0,5,10 and 15 % to natural sand for the standard w/c ratio of 0.4 is considered. The extended work is .

They found that by the partial replacement of cement with GGBS and sand with ROBO sand helped in improving the strength of the concrete substantially compared to normal mix concrete.
For example, M-sand, slag, ggbs, rockdust, silica fume and quarry waste were used in concrete mixture as a partial replacement of natural sand. Hence the assumption is manufactured sand could be an alternative to natural sand in preparation of concrete.
Maximum spilt tensile strength is achieved for cement replacement by 50% GGBS and 50% of quarry sand. Maximum compressive strength obtained for replacement of cement by GGBS 40% and natural sand by M sand 40%.
This paper deals with the implementation of steel slag as an effective replacement for sand. Steel slag, which is considered as the solid waste pollutant, can be used for road construction, clinker raw materials, filling materials etc. In this work, steel slag used as a replacement for sand, which is also a major component concrete mixture.
replacement of cement with Ground Granulated Blast furnace Slag (GGBS) and sand with the ROBO sand (crusher dust). The testing is carried out on the cube and cylinder to study the strength. The improvement in the sustainability of concrete by improving cement strength is the motive of .
M-Sand is used as a complete replacement of fine aggregate. Compressive strength are checked at 7 and 28 days for cubes of 150mm. The result shows that GGBS and Fly ash can be partially replaced with cement up to 10%. : GGBS, M-sand, Flyash, River sand, Ordinary portlandcement, Compressive strength, Concrete Pavement.
The utilization of supplementary cementation materials is well accepted, since it leads to several possible improvements in the concrete composites, as well as the overall economy. The present paper is an effort to quantify the strength of ground granulated blast furnace slag (GGBS) at various replacement levels and evaluate its efficiencies in concrete.
What is Regen?Regen Ground Granulated Blast furnace Slag (GGBS) is a cement substitute, manufactured from a by-product of the iron-making industry. Using one tonne of Regen in concrete reduces the embodied CO2 by around 900kg, compared to using one tonne of Portland Cement, and also increases its durability. Regen is more sustainable than other cement substitutes such as Fly Ash.In .
The experimental work has been carried out as partial replacement of cement with MK in M70 grade of concrete at 0%, 10%, 15%, 20%, 25% and 30% of replacements. The mix design was made making the ...

Jul 17, 2020ยท Increasing demand and depletion of natural resources in construction world, so we need for the replacement of conventional mix. In this project main o.
The replacement percentages of Cement with GGBS are 20 %, 40 % and 60 % by weight and 25 %, 50 %, 75 % and 100 % of Quarry Dust are used as a replacement of Natural Sand.
The effect of GGBS and fly ash as partial cement replacement was examined on concrete cubes, cylinder and beams. In this research paper we have kept percentage of fly ash for every trial constant except for conventional trial and GGBS was used to replace cement partially from 40% up to 70% while keeping fly ash 25% as constant throughout.
From this phase to determine the optimum percentage of quarry sand which give maximum compressive strength. It is observed that maximum strength is achieved when natural sand is partially replaced with 60% quarry sand. In second phase, the cement is partially replaced with GGBS by 10%, 20% and 30%.
implementation of steel slag as an effective replacement for sand. Steel slag, which is considered as the solid waste pollutant, can be used for road construction, clinker raw materials, filling materials etc. In this work, steel slag used as a replacement for sand, which is also a major component concrete mixture.
The present work is to use GGBS and Slag sand as partial replacement of ordinary Portland cement and river sand respectively. M20 grade of concrete with W/C 0.5 is carried out with two percentages of cement replacement by GGBS i.e., 35% GGBS and 45% GGBS. Along with this the slag
1. With the partial replacement of GGBS with sand, the strength of concrete gradually increases up to a certain limit, then it gradually decreases. 2. With the partial replacement of GGBS with sand up to 20%, the initial strength gain in concrete is high. 3. At 40%, there's 116.93% increase in initial Split Tensile strength for 28 days. 4.
