Abstract

Concrete is the world’s most versatile, durable and reliable building material in the construction industry. One of the major ingredients of concrete is ordinary Portland cement (OPC). It is the second major generator of carbon dioxide, causing pollution in the atmosphere. The process is energy-intensive. Hence, it was inevitable that an alternative material would be considered for cost-effective and reliable construction applications. Geopolymer concrete is an innovative construction material which can be produced by chemical activation of inorganic molecules such as silica and alumina bearing phases which are found in raw materials (fly ash or pond ash) used for making geopolymers. In this chapter, quantification of variables has been made relating to strength properties of geopolymer. For quantification, a statistical design of an experiment is planned, a regression equation developed, and the regression ...
