ABSTRACT
The reckless consumption of natural resources by the construction sector is making propositions of the potential utilization of abandoned by-products of various industries, for example, stone glazing, steel, and rubber industries as raw materials for concrete manufacturing. Dumping industrial wastes into rivers and lagoons is detrimental to the environment, and landfilling has lots of adverse impacts. Every year, tonnes of stone waste are produced globally during the processing of stone. Use of stone waste in concreting not only resolves its disposal issue but also economizes the product with superior quality checks and aid in environmental protection. On the other hand, chemical admixtures, that is, accelerators, trigger strength within a short time span and allow early demolding. The current study experimentally demonstrates the effects of additives, namely calcium nitrate (1%), triethanolamine (0.05%), and stone waste powder (SWP) (7.5%), on the long-term mechanical strength and durability at 180 and 365 days. The experimental results have been validated through microstructural characterization. Also, economic and ecological analysis of concrete mixtures has been carried out along with the performance index. The utilization of SWP in concreting not only improves the performance but also minimizes the negative impact on the environment by reducing cement content and cost of construction.
