Influence of curing temperature applied to hardening cement paste during the early induction period of hydrating (which is closely connected with so-called workability of concrete mixture i.e., with the period during which the material is formative and may be transported) on duration of the induction period and on the ultimate porosity of hardened samples was experimentally determined. Duration of the induction period was determined by means of electrical resistance measurements and ultimate porosity by means of the mercury intrusion porosimetric measurements. It was proved that temperatures within the range 10–65 °C whenever applied solely during induction period have a significant effect on induction period with no measurable effect on ultimate porosity of hardened cement paste.
