Studies on the Improving Performance of Ordinary Concrete
At present, the concrete applied over the world is ordinary concrete with a compressive strength less than 50 MPa, whose service life is generally 40 ~ 50 years. How to get high performance, high durability, and make its service life extend from 40 ~ 50 years to 70 ~ 80 years is of great significance in saving resources, energy and money. From the point of view of material science, the durability of concrete is mainly affected by its components, inner structure and performance. This paper studied how to adjust the components and add special mineral ultra-finest powder to make the ordinary concrete get higher durability and performance.
