In this study, the damages of high strength concrete exposed to high temperature have been evaluated by the impact echo method. Elastic wave velocity and dynamic modulus of elasticity were measured by the impact echo method, and the compressive strength and the static modulus of elasticity were measured by the compression testing method after exposure to high temperature. The results showed that elastic wave velocity has a linear correlation with the compressive strength and dynamic modulus of elasticity has a linear correlation with static modulus of elasticity. Based on results, it is concluded that the impact echo method can be effectively applied to evaluate the mechanical properties of fire damaged high strength concrete.

“…Ca(OH) 2 is a crystalline, isostructural with natural mineral of Portlandite. The cement hydration reactions are 2(3CaO.SiO 2 )+6H 2 O→ 3CaO.2SiO 2 .3H 2 O + 3Ca(OH) 2 (1) Many Spectroscopic methods, Setting time and Compressive strength have been used in various studies of cement hydration for a number of years [2][3][4][5].…”

The spectroscopicstudies have been carried out for Indian Portland cement hydrated with distilled and sea water in a water to cement ratio of 0.4. This study aims to analyze the effect of water on Portland cement. FTIR, DTA, XRD and EPR studies were used to characterize the hydration reaction of the cement pastes. Experimental results on setting time, compressive strength are also reported. The unreacted clinker phases and g-factors are calculated. The results indicate that sea water accelerates the cement hydration at early stage but retards in the latter stage of hydration.

“…The results show that: the two kinds of high strength concrete have obviously improved on chloride ion permeability after high temperature. Poon CS [22,23] studied the permeability of HSC which mix of silica fume, blast furnace slag and volcano ash which been heated to 600℃ and constant temperature 1hour. The results show that: the chloride ion permeability coefficient of all kinds of concrete has obvious rise.…”
