On the way to zero carbon
Efficient design of concrete structures
Generally speaking, concrete with a higher strength has a higher carbon footprint per tonne. However, higher strength is more beneficial and allows the use of relatively less material for the same function and therefore the carbon balance can be more advantageous for leaner structures. Precast concrete elements are usually made with a compressive strength of up to 100 MPa or more, much higher than concrete cast on site (30 MPa on average). The future is high strength concrete for structures!
