METHOD FOR PREPARING LIGHT INSULATING CONCRETE CONTAINING A CEMENT-COATED CORK OR WOOD AGGREGATE OR THE LIKE AND RESULTING LIGHT INSULATING CONCRETE

摘要

The invention concerns a method for preparing light insulating concrete containing a cement-coated cork or wood aggregate or the like and the resulting light insulating concrete. The inventive method consists in coating cork, wood or like particles of an element capable of making them inert relative to external agents. It consists in preparing a laitance with the different coating elements by mixing them with a certain amount of water, then in pouring the laitance by spray coating on the cork or wood or like aggregate, then in mixing it all until the aggregate is coated, then in drying the resulting coated aggregate.
