Which substance/material is NOT an alternative/additive to Portland cement:

A/ Ground granulated blast furnace slag

B/ Magnesium alloys powder

C/ Fly ash

D/ Silica fume

Hint: check wikipedia.com

 

[cement]

I'm guessing B since I never heard of it. That was my default on the exam too :thumbs: though I'm not sure if ground slag has cementatious properties.... what was the question?
