Improvement of Durability of Reed in Cement Media

Abstract

It is well-known that the durability of vegetable fibres, such as reed , in concrete media is very low because of high PH value of concrete.The improvement of the durability of reed in concrete media is investagated. Many coatings( namely epoxy paint,SBR,PVD, and liquid mastic) were used as wll as many types of salts ( soduim chloride,soduim sulfates and soduim nitrite).It is concluded that epoxy paint is the best coating in this respect. Soduim chloride is the best salt. It is,also, reported that no one of these measures is sufficiently effective in improvement of the durability of reed in concrete media.It seems that using reed with gysum plaster is more prac
