Abstract

Lime and lime-pozzolan-based binders are used in construction and restoration purposes for many centuries. Later its usage was reduced due to the major consumption of Ordinary Portland Cement (OPC). The usage of enormous cement in making concrete and mortar for constructing buildings and heavy structures leads to the indirect emission of greenhouse gas such as CO2 and environmental impact to earth. At this situation, use of low-carbon alternative materials for cement is suggested for sustainable practice in concrete technology. Hence, Lime is the only natural binder which plays a major role in achieving sustainability in construction. Different mineral and organic admixtures can be added with lime to increase its cementitious properties. By using these lime-pozzolan binders in construction eco-friendly, affordable and durable structures can be constructed and cement usage is minimized to a great extent. The use of lime-based binders in concrete and mortar for building and restoration applications is discussed in this paper in general terms. The fresh, mechanical, microstructural, and durability properties are the ones that are reported in this study.
