Status of Agro-Industrial Waste Used to Develop Construction Materials in Andhra Pradesh Region – India

Abstract

In today’s world concrete is one of the major construction materials. With the growth in industrialization and urbanization the demand for the concrete has taken a new pace. Therefore, to fulfill the demand huge amounts of natural resources has to be exploited for the production of the cement because natural resources and raw materials are major constituents in the production. At the same time huge quantities of industrial and agricultural wastes are generating in developing countries and are posing serious risk to the environment as well as human health. So, by utilizing these wastes as a supplementary material in construction reduces the usage of natural resources in the cement as well as decreases the threat of wastes in the environment. Many researchers have proved the effective utilization of wastes in the construction industry as they are more reliable and promote sustainability. This paper reviews waste generation and its statistics as well as environmental implication caused by wastes. It also high lights the possible ways of wastes that can be used in construction, preparation of blocks, insulators etc. This study also provides summary of existing research about usage of Agri and industrial wastes in the construction industry. In addition, paper shows application of wastes in real time construction.

Agro-industrial-based wastes as supplementary cementitious or alkali-activated binder material: a comprehensive review

“…The total wastes generated and cement manufactured globally per year are 2.01 billion and 4.1 billion tonnes, respectively, as shown in Fig. 2a, which would keep on increasing in the coming years [12][13][14]. Out of these wastes material, 44% of the contribution is from agricultural and food wastes, while remaining 56% contributes from industrial and other wastes, which is shown in Fig.…”

“…Out of these wastes material, 44% of the contribution is from agricultural and food wastes, while remaining 56% contributes from industrial and other wastes, which is shown in Fig. 2b [12,14]. According to "CemWeek research's 2020 update of the Global Ground Granulated Blast Furnace Slag Market Report and Forecast", total amount of GGBS production is about to reach 269 million tonnes between 2020 and 2025, while fly ash production which was 225 million tonnes in year 2020 would also drastically increase [15].…”

“…Therefore, the present review not only focuses on the study of agro-industrial-based wastes as SCM or AAB materials, but also the pozzolanic effects on the properties of binder Fig. 2 a Global cement and waste produced; b classification of wastes produced [12][13][14] Fig. 3 a Industrial waste produced; b agricultural and food wastes produced [15][16][17][18][19][20][21] system when it is calcined and uncalcined.…”
