In this current research the influences of local ground granulated blast furnace slag GGBS content on the properties of lightweight geopolymer concrete were illustrated The lightweight geopolymer concrete was produced by mixing a geopolymer binder with fine aggregate and keramzite as coarse aggregate Six ratios of fly ash and GGBS 100
Ground Granulated Blast Furnace Slag GGBS and Black Rich Husk Ash GGBS is obtained from JSW Cements Ltd Bellari India GGBS is one of the primary binders to produce geopolymer concrete GPC conforming to the specifications of BIS 12089 1987 [] BRHA is obtained from the rice mill near Karaikudi
Geopolymer concrete is made with the partial replacement of CS for fine aggregate with Fly Ash used as a cementitious material Ground granulated blast furnace slag cement produced from iron
The present investigation aims to use recycled coarse aggregate RCA and ground granulated blast furnace slag GGBFS as replacement of natural coarse aggregate NCA and ordinary Portland cement OPC for developing sustainable concrete Sixteen numbers of concrete mixes are prepared with 0% 25% 50% and 100% replacement of NCA by RCA for
The CWAs were porcelain insulator wastes supplied from an electric power company which were crushed and ground to fine aggregate sizes In this study to further develop the CWA mortar as an eco efficient construction material ground granulated blast furnace slag GGBS was incorporated
Three concrete mixes have 0% 50% and 100% recycled coarse aggregates RCA and 60% ground granulated blast furnace slag GGBFS for each mix Other three concrete mixes have RCA percentage of 0% 50% and 100% and the combination of 7% lime and 60% GGBFS for each mix The characterization of these concrete mixes includes the evaluation of
Ground granulated blast furnace slag GGBFS and metakaolin MK are two typical precursors used for preparing Ca containing and Ca free AAMs respectively and they show different alkali activation processes and different compositions and properties of the alkali activation products This review is mainly focused on the progress made in
The compositions of Ground Granulated Blast Furnace Slag GGBFS varied by 0% 25% 50% 75% with the coarse aggregate composition of 40% against natural aggregate The use of 50% GGBFS gave the
In this paper the aim is to analyze and to model the deformational behavior under compression and bending of SCC containing 100% coarse and 0% 50% and 100% fine Recycled Aggregate RA limestone and RA green aggregate powders sized 0/ mm and Ground Granulated Blast furnace Slag GGBS cement
For fine aggregate the river sand of Zinda peer quarry was used whereas crushed dolomitic sandstone of Kirana Hills quarry was used as coarse aggregate The maximum aggregate size for fine and coarse aggregates are and mm respectively while water absorption values for fine and coarse aggregates are % and % respectively
Researchers have been investigating to utilize BOF slag effectively and some have contributed to promote that BOF slag as an aggregate can be used in concrete asphalt and road construction Xie et al 2012 However BOF slag contains high free lime about 40% which causes volume expansions which dragged many researchers attention and therefore
Abstract Concrete is a mixture of cement fine aggregate coarse aggregate and water Concrete plays a vital role in the development of infrastructure Viz buildings industrial structures bridges and highways etc leading Ground Granulated Blast furnace Slag GGBS [1] is a by product from the blast furnaces used to make
