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
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.
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 .

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. Various types of slag are produced: Blastfurnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast .
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)
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 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
products in concretemaking 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].
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.
