What is the gel/space ratio?
(a) Volume of water to the volume of cement
(b) Volume of the hydrated cement paste to the sum of volumes of the hydrated cement
(c) Volume of the hydrated cement paste to the sum of volumes of the hydrated cement and of the capillary pores
(d) Volume of gel to the volume of space present in the concrete
The question was posed to me in an interview.
My question is from Gel Space Ratio in section Strength of Concrete of Concrete Technology
