Review of lime as a binder and finish material & its applicability in the current context
Before the 20th century, lime mortar and lime plaster were widely used in old and historical buildings. In addition to the soothing appearance, it imparts to the building lime plaster has excellent moisture-buffering properties. The usage of lime saw a decline when Portland cement was introduced in the 19th century. However, lime has numerous advantages as a binder and finish material. Lime is capable of self-healing by the autogenous process due to the evaporation of penetrated water. This is especially needed in the case of old and historic buildings. Previous experimental work with lime and cement cells showed lower temperature and relative humidity in the lime cell. The composition of lime is highly variable due to its inherent composition and difference in additives from region to region. The objective of this work is to review the literature comprehensively and report information regarding history, availability, composition, types, properties, practices, codes & standards, applications, and case studies with lime as a binder (mortar material) and finish material. The same is necessary to study the relevance of lime in current construction practices.
