Development of Eco-efficient Geopolymer Masonry for Sustainability

Abstract

Geopolymer has been considered a popular alternative to traditional cement. Materials which are rich in silica and alumina can be used along with traditional aggregates to prepare geopolymer mortar and masonry units. This chapter deals with the development of geopolymer masonry units such as brick (GPB), solid block (GPSB) and hollowblock (GPHB).All these productswere tested for dimensionality, water absorption, strength, modulus of elasticity, etc. They possessed better properties compared to traditional masonry units. The same units were used for making masonry prisms, and wallets. The prisms and wallets were loaded with axial and eccentric loads and tested for compression. The modulus of elasticity was also determined along with the crack pattern. Results indicated that the prisms and wallets performed exceedingly well compared to the traditional masonry structures. Moreover, no traditional cement is required in any stage of construction. The traditional water curing and thermal input is avoided. Based on this study, geopolymer masonry units are strongly recommended for the structural masonry without compromising properties.
