- Abstract
With the refinement and further implementation of the action plan of carbon peak and carbon neutralization goals, low carbon has become the development direction of all walks of life in China in the future. This study used mineral powder and fly ash from industrial solid waste to replace cement in large quantities. And then, applying a dilute sulphuric acid solution of 5% mass fraction to simulate an acidic corrosive environment, in order to develop low carbon concrete with acid resistance. The results showed that the early strength of concrete mixed with mineral powder and fly ash is not high, while the long-term strength is better; A large amount of fly ash and ultra-fine mineral powder can make the concrete more dense inside, the inhibition of sulfuric acid invasion and chemical reaction is beneficial to control the quality change of concrete caused by sulfuric acid erosion, and also can effectively reduce the neutralization depth of sulfuric acid.
