Synthesis and Properties of Lightweight Geopolymer using Ash from Thermal Power Plants


Article Preview

A lightweight inorganic polymer is obtained using ash from thermal power plants, metakaolinite and lightweight aggregate. This inorganic material is activated using small amounts of sodium hydroxide and sodium silicate solution. Processing parameters and various curing conditions, such as curing temperature, curing time and moisture, are investigated. Compressive strength, rate of water absorption and density of each sample were measured.
