Strength Assessment on Geopolymer Concrete using Ceramic Waste Powder and M-Sand

Abstract

The use of abundantly available wastes such as Fly ash and ceramic powder in construction industry in the form of geopolymer concrete turns out to be the search of a very promising building material for a sustainable future[15].This study has been undertaken to investigate the strength and durability properties of geopolymer concrete by adding ceramic powder in different percentage as source material in addition with flyash[16]. All investigations are mainly focused towards geopolymer concrete mainly with flyash as source material. In this study, ceramic waste powder is added since it is also one of the major waste material as flyash. Nowadays, almost all the construction are carried out with ceramic products which results with more ceramic waste powder. Thus this work focused to utilize this waste powder into geopolymer concrete. Characteristic strength and primary durability properties are carried out by adding ceramic powder with 50%,40% and30% with fly ash. Thus this paper focuses on varying the proportions of fly ash and ceramic waste powder (50:50, 60:40, 70:30) in geopolymer concrete incorporating with polypropylene fibres in percentage of 0.5%,0.75% and 1% in volume of concrete to evaluate its strength and durability characteristics. The alkaline activator solution used is a mixture of 10 molar Sodium hydroxide and Sodium silicate in the ratio 1:3. Ambient curing condition is applied for the specimens. M-Sand is used instead of fine aggregate, since many literature reveals addition of M-Sand gains more strength in geopolymer Concrete.
