sandstone plum (加于毛石混凝土中用)
3.Corrosion inhibitor admixtures shall be defined as materials that when added to concrete have the ability to reduce the potential of corrosion of embedded steel.
4.The ultra high strength aerated concrete can be produced by using the techniques of admixture and activatory fly ash in fly ash aerated concrete. Its compressive strength is 8 0～10 0MPa and density is only 800 kg/m 3. That is called load bearing areated concrete which is applicable for load baring wall in masonry construction.
5.Final results of experiment indicate that adding some synthetic fiber to HPC with the mineral admixture or cement mortar can decrease cracking 95% at least and enhance the durability of concrete.
6.The experiments for sulfate corrosion on concrete with high activity and superfine admixture (FC admixture) are carried out. The tests show that the concrete resistance to corrosion can be greatly increased by adding proper FC admixture into concrete.
8.To add a fluorine compound to(a drinking water supply, for example) for the purpose of reducing tooth decay.
