In this fast developing world, it becomes very important for us as Civil Engineers, Architects and Builders to focus both on the global development and also its impact on the environment. This kind of approach leads to many innovations and researches which helps in conserving the environment without compromising on the developments. Construction industry has been associated with the materials which were being used about a century back and are still very popular. Variety of alternative building materials which are eco-friendly and sustainable are made available which provide better, efficient, durable and cost effective construction and also ensure judicious utilization of available limited resources with least possible degradation of environment.
Building materials and technologies and building practices have evolved continuously. Housing and building conditions reflect the living standards of a society. Stones, mud, thatch and timber represent the earliest building materials used for the construction of dwellings. Hardly any energy is spent in manufacturing and use of these materials for construction. Durability of the materials, directly derived from the natural materials like soil, thatch, timber etc. is questionable.
The demand for building materials has been continuously rising with the increasing need for housing both in rural and urban areas. Commercial exploitation of traditional building materials by various industries has aggravated the situation. It has, therefore become necessary to think over this problem seriously and to provide some sustainable solution to make the alternative materials available to solve the housing problem.
A large number of viable alternative building materials and technologies have been developed and disseminated in the recent times. Some of these materials are supplementary cementitious materials(SCMs) like Flyash, GGBS, Ultrafine Slag, Ultrafine fly ash, Micro silica, Metakaolin, Rice husk ash which help in partial replacement of OPC Cement. Pertonne of OPC Cement liberates about 0.6 to 0.8 tonne of CO2 in manufacturing process contributing to 5 to 6 % of the total global CO2 emissions and also consuming about 1.5 tonne of Lime stones from Nature.
