The strength of concrete is
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). The topic deals with the usage of GGBS and advantages as well as disadvantages in using it in concrete. This usage of GGBS serves as replacement to already depleting conventional building materials and the recent years and also as being a by
that by the partial replacement of cement with GGBS and sand with ROBO SAND. III. Ground granulated blast furnace slag (GGBS) GGBS is granular material formed when molten iron blast furnace slag is rapidly chilled by immersion of water. It is a granular product with very limited crystal formation, is highly cementations in nature ...
as a replacement of Natural Sand due to its scarcity. The replacement percentages of Cement with GGBS are 20%, 40% and 60% by weight and 25%, 50%, 75% and of Quarry Dust are used as a replacement of Natural Sand. Various combinations of GGBS and Quarry Dust were prepared using M30 Grade of Concrete.
Use of Iron Slag as Partial Replacement of Sand to Concrete. ... (Ground Granulated Blast Furnace slag) as a replacement for cement. Keywords: River sand, steel slag, OPC, GGBS, M Sand, compressive strength. Get Price. effect of partial replacement of sand by iron slag ... - Thapar University
ground granulated blast furnace slag (GGBS). This needs to examine the admixtures performance when blended with concrete so as to ensure a reduced life cycle cost. The present paper focuses on investigating characteristics of M40 grade concrete with partial replacement of cement with ground granulated blast furnace slag (GGBS) by replacing
Mathematical model approach for suitability of GGBS as a replacement… 1749 Replacement levels for GGBS vary from 25% to up to 80%.GGBS cement is slightly less expensive than Portland cement, concrete made with GGBS cement will be similarly priced to that made with ordinary Portland cement. Shariq et al (2008) studied
Ground Granulated Blastfurnace Slag (GGBS) and sand with the ROBO sand (crusher dust). The cubes and cylinders are tested for both compressive and tensile strengths. It is 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.
May 09, 2018· The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components
The replacement level of GGBS can be as high as 70% of cement, which is about twice as much of PFA (typically replacement level is 40%). Hence, partial replacement of GGBS can enable higher reduction of cement content. As the manufacture of one tonne of cement generates about 1 tonne of carbon dioxide and it is considered more environmentally ...
GGBS along with sand the required concrete mix can be obtained. stone sand, crusher sand and crushed fine aggregate. One of the main objectives of this project is to determine the concrete strength of M30 Grade by partial replacement of sand by copper slag and GGBS. The concrete
