It is widely used in civil engineering. In the process of urbanization, the national infrastructure construction has suddenly risen, and the demand for concrete has soared, which will inevitably lead to an increase in the use of cement and medium sand. In the process of the sudden rise of infrastructure, the use of concrete cement and medium sand has increased. The CO2 implied in the carbon footprint of concrete mainly comes from cement. Although the carbon emission per unit weight of concrete is not high, when multiplied by the huge consumption required for global infrastructure, it will inevitably lead to a rapid increase in the total carbon emission. It is necessary to study a new type of low-carbon desert sand concrete with a carbon footprint lower than the traditional content, that is, low-carbon desert sand concrete. The promotion of this new type of low-carbon desert sand concrete can not only reduce the formation of carbon footprint, reduce engineering costs, protect the environment and save resources, but also enable the environmentally friendly and easily available slag powder and fly ash, and desert sand resources to be reasonably developed and reused.
