A Study on the Development of Ternary System Concrete Strength for Improving Durability of Concrete in CFT Structure
Abstract
The purpose of this study was to analyze strength development of ternary system concrete for Improving Durability
of Concrete in CFT Structure The specimens were made with normal portland cement and pozzolan materials with various
replacement ratio and with W/B ratio ranging from 0.55. Compressive strength were determinated for for the test. Concretes
made with these proportions generally show excellent fresh and hardened properties since the combination of silica fume and
fly ash, silica fume and blast-furnace slag is somewhat synergistic. For instance, fly ash appears to compensate for some of the
later compressive strength often associated with the use of higher levels of silica fume, whereas the silica fume appears to
compensate for the relatively low early strength of fly ash concrete. And the later hydration of blast-furnace slag is very
effective in producing ternary system concrete with similar or higher compressive strength than portland cement at 28 and 90
days. Therefore ternary system concrete is improving the early and the later compressive strength. Also the use of ternary
system concrete provides economic and environmental advantages by reducing portland cement production.
