“Solid industrial waste generation and its valorization in developing sustainable building materials- A state of the art review”

Abstract

Eco-efficient product development is going to be essential for the construction industry from the sustainability point of view as one way it lower down the environmental burden and another way it emphasizes on solid waste management to protect the mother nature. This study is intended to carry out the literature review to identify the various waste which has been used in mortar developments in 21st century (from year 2000 to year 2022). Waste has been selected from various industry i.e. Glass Waste, Marble Waste, Sandstone Waste, Limestone, Plastic Waste, Wood Waste, Construction and Demolition Waste, Ceramic Waste, Sludge from treatment Plants, Shell Waste, Rubber Waste, Bio Waste, Ashes etc. the literature review shows that these wastes can be utilized in the mortar development with a certain quantity as a substitute to fine aggregate or Natural Sand. The amount of substitution depends on the various parameter of the waste i.e. Physical, Chemical, morphological characteristics along with the ease of production, Transportation, Durability etc. in recent time most predominantly used waste in mortar development is found to be Glass Waste, Manufacturing Industry Waste, Construction and Demolition Waste and ceramic Waste. The literature collected for two decades from year 2000 to year 2022 has suggested optimum fraction of sand substitutions as 20% to 30% subjected to fresh and hardened properties, Durability, Morphological consideration, Microstructural Assessment. The ideal and most commonly used fraction of waste for mortar development can also be determined.
