Copper slag is classified as pozzolanic material according to ASTM standard, so there might be reaction with the activators used in geopolymer concrete. 10th Oct, 2015 B.M. Mithun
The used Pozzolanic materials were three types of Fly ash, two types of Metakaolin and one type of ground granulated blast furnace slag. Geopolymer concrete samples .
products in concrete-making will lead to sustainable concrete design. The industrial as well as other wastes such as copper slag, oil palm shells, wood waste ash, fly ash, granite sludge, cement kilns dust, steel chips, silica fume, rice husk ash etc. were used in concrete to improve the properties of concrete and to reduce the cost [5,6].
International Journal of Research (IJR) Vol-1, Issue -8, September 2014 ISSN 2348-6848 EFFECT OF COPPER SLA G AS A PARTIAL REPLA CEMENT OF FINE AGGRE GATE ON THE PROPERTIES OF CEMENT
copper slag improve the 17.5%, 13.94% and 22.72% at 28 days compressive strength, split tensile and flexural strength is comparison the geopolymer concrete without copper slag. The water is absorbent durability of geopolymer concrete. P. Meenaksh (2017) studied on partial replacement of
copper slag in cement mortar. Test cubes of mortar were built according to the standard Nch 2260, Of1996 (INN, 1996a) in the form of prismatic bars having, dimensions of 40 x 40 x 160 mm (width, height and length) with mixtures of cement, water and sand. It was observed that the compressive strength of mortar using copper slag is higher
An effort in this regard is the development of geopolymer concrete, synthesized from the materials of geological origin or by product materials such as fly ash, which are rich in silicon and aluminum. This paper presents results of an experimental study on the density and compressive strength of geopolymer concrete.
Aug 20, 2014· Abstract. This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering.
utilizing LD slag by geopolymer concrete and trying explore the potential of steel slag as one of the raw material for making geopolymer concrete of M20 grade and steel slag has a lower reactivity in geopolymer system and it was used in combination with fly ash and granulated blast furnace slag. The
A concrete using cement alone as a binder cementing materials such as Fly Ash, Silica Fume, requires high paste volume, which often leads to excessive Granulated Blast Furnace Slag, Rice-Husk Ash and shrinkage and large evolution of heat of hydration, besides Metakaolin, and finding alternative binders to Portland increased cost.

Apr 10, 2019· The copper slag (CS) used in the present study was provided by Boliden industry, which produces copper and other metals such as zinc, lead, nickel, gold and silver. For the preparation of geopolymers, an adequate quantity of granulated slag was grinded to a particle size − 180 μm. ... The temperature at the geopolymer/concrete interface was ...
Geopolymer concrete also is known as green concrete or cementless concrete produced by replacement of cement with the waste product obtained from the industries. Geopolymer concrete uses fly ash, slag, and rice husk as a binder which is a substitute for conventional concrete.
This article investigated the potential of fly ash (FA)/blast furnace slag- (BFS-) based geopolymer as a novel backfilling material. The effects of NaOH concentration and FA/BFS mass ratio were explored through XRD, FTIR, and TG-DTG analyses. The results indicated that the reaction products and strengths of geopolymer depended on the NaOH concentration and types of source materials.
Geopolymer concrete shows significant potential to be a material for the future; because it is not only environmentally friendly but also possesses excellent mechanical properties. Practical recommendations on use of geopolymer concrete technology in practical applications such as precast concrete products and waste encapsulation need to be ...
geopolymer concrete might yield additional economic benefits when utilized in infrastructure applications. When the strength and cost for the different mixes are compared it can be concluded that geopolymer concrete with copper slag shows improved strength characteristics and helps in reducing the cost for production.
Aug 01, 2019· The present investigation is mainly focused on studying the flexural behavior of reinforced geopolymer concrete (RGPC) beams under pure bending. In this study, copper slag (CS) was used as a partial replacement of fine aggregate. Sand and CS were blended in different proportions (100:0, 80:20, 60:40 and 40:60) (sand:CS) by weight. Fly ash and ground granulated blast furnace slag (GGBS) .
