Pozzolan-based additive agent and uses thereof

Abstract

An additive agent comprising pozzolan and methylcellulose, for the preparation of a concrete mixture of a hygroscopic vegetal-based concrete material comprising lime and the additive agent is described herein. The lime may be hydrated lime and the pozzolan may be a metakaolin. Proportions of each element are between 50% to 80% by weight of lime, between 20% and 50% by weight of pozzolan and between 0.3% and 1.5% by weight of methylcellulose. A concrete mixture and a solid concrete material made from such mixture include hemp hurds as an aggregate. The additive agent may also be used in the preparation of a concrete mixture or of a binder formulation for use in the concrete mixture. A variety of applications including prefabricated construction components are made from this material.
