Environmental impact of concrete - Wikipedia The environmental impact of concrete, its manufacture and applications, are complex, driven in part by direct impacts of construction and infrastructure, as well as by CO 2 emissions; between 4-8% of total global CO 2 emissions come from concrete. Many depend on circumstances. A major component is cement, which has its own environmental and social impacts and contributes largely to those of ...

What is the crushing strength of M50 grade concrete? - Quora Crushing strength is another term for compressive strength. M50 denotes concrete mix with a characteristic cube compressive strength denoted by fck of 50 N/square mm or 50 MPa. In other words, M50 grade concrete possess a crushing strength of 50 N/square mm or 50 MPa.
