Green concrete is a more trustworthy and sustainable material in the concrete industry. Green concrete, created by Dr W.G. in 1998, was first utilised in Denmark. This concept calls for taking the environment into account throughout the entire concrete technology cycle, from creation to demolition. Green concrete is made using at least one waste product as a basic component. While maintaining the excellent quality of the completed product, it is both practical and advantageous to use the waste from other industries in the production of concrete. Water use has decreased by about 20%. Public awareness of the negative environmental effects of residual product deposits has increased during the past ten years. These goods are subject to high tariffs and use limitations. Some of these waste products can serve as the foundation for environmentally friendly concrete production. It has been found that well-known residual products including silica fume, fly ash, and micro silica are the most efficient raw materials. Around fifty countries have active marble industries, and there are over 15 billion cubic metres of marble resources worldwide. Pakistan is expected to have marble reserves that total more than 300 billion tonnes. Pakistan produced 4.9 million tonnes of marble, of which 2.15 million tonnes came from Baluchistan, and 0.82 million tonnes in FATA region. The marble stones are cut with water by the businesses in Pakistan, producing a large amount of waste marble slurry, 90% of which is less than 200 m when dried.
