Properties of alkali-activated fly ash :

 I studied different research papers based on the above topic and I concluded that :

• The mortar and concrete made with Portland cement, free activated fly ash develop a highest mechanical strength
• Less time required to gain enough strength
• It has a moderate modulus of elasticity
• Better Bond formation of Steel reinforcement
• Its shrinkage capacity is very less as compared to ordinary Portland cement concrete

Optimisation of alkali-activated fly ash :

• Actually conductive alkali-activated Ash is formed using carbon fibres
• Optimisation of alkali-activated fly ash is done when we use 0.3% Carbon fibre content 25 to 30 per cent ceramsite content and 70% slag content

Thank you.
