METHOD FOR PRODUCING CONCRETE OR MORTAR USING A VEGETAL AGGREGATE

摘要

The invention relates to a method for producing cement or mortar based on exclusively vegetal aggregate, a mineral binding agent, and mixing water. Instead of premineralising the vegetal aggregate in a separate operational step, 4-14 kg per cubic vegetal aggregate metre of finely ground, non hydrateable mineralisator is added when mixing the concrete or mortar. A preferred minerialisator is raw calcium carbonate.
