What is the different in chemical composition between 32.5 and 42.5 Portland cement? Thank you.
Chemical composition

I’m not sure there is any diference in the chemical composition, only the size of the granuales. Here’s some more info for you…
32.5, 42.5, 52.5 indicate the minimum desired resistance value achieved within 28 days. 32.5 can be used in general-purpose construction to produce concrete where the hydration temperature and effects of sulfur do not require that special attention be given. PC 42.5 and PC 52.5 are used in construction works where highly resistant concrete is desired or where concrete with a high initial resistance to shock is required.
Hope this helps.
