THE DURABILITY AND DEGREE OF AGING OF GFRC WALL PANELS AFTER TEN YEARS OF SERVICE ON A BEACHFRONT BUILDING NEAR BOSTON MASSACHUSETTS IN THE USA

摘要

Extensive testing of the 9 to 10 year old GFRC was performed by both the IE and WJE. The flexural properties measured on 46 different specimens taken from 5 different wall panels found that the MOR, PEL, and flexural tensile strain properties of the GFRC were normal and within the ranges expected for GFRC as manufactured in the USA. In addition their was nothing abnormal about the strain capacity of the in situ panels and the majority were not fully aged. The measured densities and absorption values indicate that the GFRC was produced and cured properly.
