METHOD FOR SELECTING THE COMPOSITION OF A CONSTRUCTION MATERIAL COMPRISING AN EXCAVATED CLAY SOIL, METHOD AND SYSTEM FOR PREPARING SUCH A CONSTRUCTION MATERIAL

摘要

The invention relates to a method (100) for selecting the composition of a construction material comprising an excavated clay soil, the composition of the construction material having to comprise quantities of deflocculant agent and activation agent which are suitable for the excavated clay soil, the method comprising a step (130) of receiving a measured value for at least one physicochemical property of an excavated clay soil and a step (170) of selecting a quantity of deflocculant agent and a quantity of activation agent which are suitable for the excavated clay soil. The invention further relates to a method (200) for calibrating a calculation algorithm for establishing the composition of a site construction material, a construction material which is formed from an excavated clay soil and a system (400) for preparing a construction material comprising an excavated clay soil.
