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%.
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 .
The reactivity of glass that limits its use as an aggregate does allow it to be used as a cement replacement at levels of up to 20%. As the amount of energy required to produce cement is quite large this has a more positive environmental impact than the use of glass as a replacement for sand. 7.10.2 Glass with bitumen
Jan 28, 2020· How GGBS is Made inside Steel manufacturing Factory On our planet, Iron is not found in pure state, we call it as ore. Iron Ores are often oxidized and mixed with Silicates (sand). During manufacturing of steel these ores are heated above 1600 degree centigrade in .
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.
Ground Granulated Blast furnace Slag (GGBS) as partial replacement to cement, waste river pebbles obtained after sieving sand as partial replacement of coarse aggregate, crushed rock fines(CRF) as partial replacement to natural to sand ; on mechanical properties of concrete. The strength of concrete is
P. N. Raoet al focused on investigating characteristics of M30 concrete with partial replacement of cement with ground granulated blast furnace slag(GGBS) and sand with ROBO sand(crusher dust). The cubes and cylinders are tested for both compressive and tensile strength.
The river sand is used as fine aggregate conforming to the requirements of IS: 383-1970. Having specific gravity of 2.62 and fineness modulus of 2.86 has been used as fine aggregate for this study. ... replacement of GGBS is 7.67 N/mm2 as shown in Table -9. 9. The Flexural strength strength showed a .
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 ...
Replacement Of Cement By GGBS And Sand By Poly Propylene Plastic Challa. Nithin Kumar Reddy, Jonnalagadda Rakesh . ECO Friendly Concrete By Using Partial Replacement Of Cement By GGBS And Sand By Poly Propylene Plastic 65 28days avg compressive strength3 The total experiment is carried for M 30 grade of concrete with partial ...
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.
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.
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.
GGBS is used as a direct replacement for Portland cement, on a one-to-one basis by weight. Replacement levels for GGBS vary from 30% to up to 85%. Typically 40 to 50% is used in most instances. For on the ground concrete structures with higher early-age strength requirement, the replacement ratio would usually be 20 to 30%.
GGBS, sheet glass powder, M sand, washed bottom ash, construction and demolition waste are used as a replacement of sand in concrete for construction.
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
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 .

From structural point of view, GGBS replacement enhances lower heat of hydration, higher durability and higher resistance to sulphate and chloride attack when compared with normal ordinary concrete. On the other hand, it also contributes to environmental protection because it minimizes the use of cement during the production of concrete.
It is used in sand industry and in the manufacture of abrasive tools. Used to remove rusts, old coating and dry impurities. 3.1.4 Ground granulated blast furnace slag (GGBS) GGBS is used in this study for the partial replacement of Portland cement. GGBS is the by-product obtained during the manufacture of .
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%.
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.
