Effect of nano CaCO

Through comparatively analyzing the impermeability and compressive strength test data of nano CaCO3 concrete with different content, this paper puts forward the method of optimizing the durability of nano CaCO3 concrete, and studies the influence of the content of fly ash on the durability of nano CaCO3 concrete on this basis, so as to provide a reference for improving the durability of concrete, so as to improve the recycling and reusing efficiency of building materials, and accelerate the practical application of nano CaCO3 concrete in engineering
