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, RiceHusk Ash and shrinkage and large evolution of heat of hydration, besides Metakaolin, and finding alternative binders to Portland increased cost.
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.

Apr 07, 2018· Geopolymer concrete (GPC) is becoming a sustainable concrete when comparing to ordinary Portland cement (OPC) concrete. This investigation is mainly focused on the preliminary study on fly ash (FA) and ground granulated blast furnace slag (GGBS) based GPC using copper slag (CS) and vermiculite (VM)
In this paper, fly ash is used to produce a geopolymer concrete. Geopolymer is a material resulting from the reaction of a source material that is rich in silica and alumina with alkaline solution. Geopolymer concrete is totally cement free concrete. In geopolymer, fly ash act .
Mar 27, 2019· In this study the replacement of sand with copper slag in geopolymer concrete varying the percentage of 0%, 10%, 20%, 30%, 40%. The concentration of sodium hydroxide solution is 14M. Alekhya et al studied the strength of M30 grade Glass Fiber Reinforced Geopolymer 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 TGDTG analyses. The results indicated that the reaction products and strengths of geopolymer depended on the NaOH concentration and types of source materials.
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.
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.

geopolymer concrete with copper slag. Preliminary Investigation physical and chemical properties of various materials as cement, fine aggregate, coarse aggregate, copper slag. Fly ash is tested and the properties are compared with each other. Fresh and hardened properties of conventional concrete
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
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) .
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 Mithun
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 ...
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
Sep 30, 2019· The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials.
