Low modulus of elasticity
When also measured up to the 6 months deadline and kept in a damp atmosphere, these mortars present practically the same dosing modulus.

Natural prompt cement has a low shrinkage, with very small dimensional variations.
Thanks to the retardant additive Tempo, setting can be delayed in applying of Prompt natural cement, which is a quick-setting cement (2 minutes in mortar at 20°C). Tempo is available in doses of 80 grams, and is dosed in relation to the volume of Prompt natural cement used. It is added to the mortar or concrete preparation.
Quick setting of natural prompt cement enables to handle only small quantities at one time (e.g. a few liters) the use of a retardant brings than comfort of usage, leaning more time for work and tools cleaning.
