The Effect of Pore Structure and Water Absorption on Carbonation Resistance of Sulphoaluminate Cement Foam Materials

Abstract:

Researched the influence of the pore structure and water absorption on the carbonization property with sulphoaluminate foamed cement as an example. The results showed that: Under the same levels of dry density, the smaller pore size, the higher the carbonation coefficient and the integrity of pore had the same effect. After the surface water-proofing, water absorption decreased by 10% on average, the time of carbonizing completely become longer, and carbonation coefficient was increased. And put forward the methods of improving the carbonation resistance properties of sulphoaluminate cement foam materials.
