Abstract
The subject matter of the invention is a new additive for mineral binders comprising a composition containing at least one product of internal dehydration of a hydrogenated sugar which can especially be a dehydrated hexitol such as isosorbide, isomannide, sorbitan or mannitan and which can be introduced at a rate of between roughly 0.001 and 5% (dry/dry) within any mineral binder, said additive being advantageously used as an accelerator for setting and/or hardening and/or as an agent for improving the mechanical properties of the mineral binder. It has a remarkable efficiency, including at low temperatures.
