What is the effect of fly ash when it partially replaced with cement and how it will affect the following properties:

1. Workability
2. Compressive strength
3. Flexural strength
4. Hardness
5. Moisture content
6. Hardened density

Please I want to know if the properties above will increase or decrease when the fly ash is partially replaced with cement and why?
