The durability of fiber glass protected with epoxy-phenol coatings in portland cement mortar was investigated. Aging and stress corrosion tests to 2 years, indicate normal fiber qlass must be protected completely with a pinhold free coating to withstand alkali attack over lonq periods as well as a coating which will migrate into the mortar to afford good bond strength.
