Carbonation resistance
Durability Research of Service Concrete
The issue is from the National Science Foundation project “durability of concrete in service”, grant No.:51068023.As known to all, durability of concrete is restricted by three factors:first, quality of materials; second, pore structure; third, corrosion agent. Now the method to test concrete durability was only established on materials. The factors of quality of materials and [...]
Research on the Composition and Properties of Phosphogypsum Based Cement
In this study, energy saving and emission reduction of cement industry were combined with the utilization of phosphogypsum (PG). Phosphogypsum based cement (PBC) had been developed by using PG as the main raw material and adding appropriate amount of slag, limestone and a small amount of Portland cement clinker. And through a large number of [...]
Experimental Study on Mechanical Properties and Carbonation Resistance of Air-entrained Concrete
China is now in the large-scale period of construction, concrete is seen as a very important building materials, the durability of concrete is directly related to people’s livelihood. The main factor is steel corrosion which led durability of reinforced concrete structure to deteriorate, and in the general atmospheric environment, carbonation of concrete reinforcement corrosion in [...]
