Gel space ratio
Gel space ratio is defined as the ratio of the volume of hydrated cement paste to the sum of the volume of hydrated cement and of capillary pores.
Case-I
\(\rm \frac{0.657 C}{0.319 C + W_o}\)= Calculation of gel / space ratio for full hydration
where Wo = volume of mixing water in ml, C = weight of cement in gm
Case-II
\(\rm \frac{0.657 C}{0.319 C\alpha + W_o}\)= Gel space ratio for partial hydration
where Wo = volume of mixing water in ml, C = weight of cement in gm; α = fraction of cement that has been hydrated
