This report presents the results of the investigation on the influence of steam uring on GFRC using GFRC cement of los alkaline type. The glass fiber content and condition of steam curing were varied. Prism specimens were tested for compressive strength, flexural strength, shear strength, drying shrinkage and load-deflection curve. These investigations provided the following results; The strength of GFRC using GFRC cement became higher with the increase in the presteaming period and in the wet curing period after steam curing. Not only the early-age strength development but also the later strength development for steam-cured GFRC using GFRC cement were improved comapred with GFRC using ordinary portland cement. The adoption of steam curing was effective in decreasing the drying shrinkage of GFRC. The toughness of GFRC using ordinary portland cement was not so good after the curing period. Especially, the wet-cured GFRC gave the lowest value. It was considered that the alkali resistant properties of GFRC could be improved by the use of GFRC cement.
