TLDR
In this article, the importance of green concrete and its applications, advantages, and disadvantages are discussed, and the results are varying for different structures based on different types of concrete structures.Abstract:
Green concrete is a type of concrete. It is a sustainable material used for the construction of reinforced concrete structures. Green concrete is different compared to normal concrete. Nowadays, it plays a very good role in the construction of structures. It is subjected to very low energy consumption and low resource consumption. Green concrete is a very good material for sustainable development. Concrete is made from the replacement of substituent ingredients such as cement and aggregates. In this waste materials such as agricultural or industrial wastes are placed during manufacture to produce a new concrete. Green concrete is popular worldwide due to its extraordinary properties and applications. This paper mainly deals with the importance of green concrete and its applications, advantages, and disadvantages. The results are varying for based on different structures. So, we can get all characteristics and properties of concrete structures and know their strength.read more

Fracture Performance of Cementitious Composites Based on Quaternary Blended Cements
TL;DR: In this article , the fracture mechanics parameters of new concrete composites based on quaternary blended cements (QBC) have been investigated and a composition of the two most commonly used mineral additives, i.e., fly ash (FA) and silica fume (SF), in combination with nanosilica (nS), has been proposed as a partial replacement for ordinary Portland cement (OPC) binder.

Development of High-Performance Green Concrete using Demolition and Industrial Wastes for Sustainable Construction
TL;DR: Sadek et al. as discussed by the authors investigated the feasibility of recycling air-cooled slag (ACS) as a substitute of natural coarse aggregate on the strength and durability of high performance concrete containing natural aggregates or a blend of natural aggregate and recycled concrete aggregate as a new approach to massively recycle these wastes for sustainable construction.
