Abstract: A binding resin, particularly for manufacturing articles, the method for its preparation, and articles that can be obtained with the resin. The binding resin is obtained by mixing essentially a first powder that comprises silica and one or more hardening agents with a solution of at least one silicate of an alkaline metal. Some of the possible additional ingredients are a powder that comprises at least one pozzolanic inorganic binding agent, at least one pozzolanic binding agent with high specific surface area, and a solution of at least one waterproofer. The addition of the optional ingredients provides additional advantages. The invention also relates to a method for preparing and using the resin and to the products (or articles) that can be obtained from the resin.
