Abstract
The invention relates to a method (100) for producing a prefabrication element and to a construction binder including a raw clay matrix, a deflocculation agent and an activation composition, wherein: the raw clay matrix includes at least one raw clay from the smectite family; the at least one raw clay from the smectite family represents at least 20% by weight of the construction binder; and the construction binder comprises less than 15% by weight of Portland cement.
Claims18
A construction binder comprising:
- from 2% to 40% by dry weight of an alkaline activation composition;
- at least 40% by weight of a raw clay matrix, the raw clay matrix comprising at least one raw clay from the smectite family;
- the at least one raw clay from the smectite family representing at least 20% by weight of the construction binder;
- at least 20% by weight of a calcined metal oxide composition;
- less than 15% by weight of Portland cement, and
- a deflocculation agent.
