These results are from the different of amorphous phase and reactivity of the replacement materials.
Therefore, class C fly ash was replaced with replacement materials, i.e. kaolin, metakaolin calcined at different temperatures of 600°C and 700°C to modify the setting time and study the effect of replacement materials on the compressive strength.
Fig. 1 showed the phase analysis of fly ash and all replacement materials by XRD.

Introduction There is an increasing attention on fiber-reinforced composites as advanced materials for a wide range of applications due to their superior properties such as high strength and stiffness to weight ratio.
Material and Sample Preparation The materials used were continuous roving carbon T700 Toray and E-glass fibers reinforced with epoxy resin.
The high increasing of energy especially on H1 and H4 samples was a result of further collapse and progressive failure in the fibers of pipes constituent materials.
