摘要： A method of producing a mainly carbonate bonded article includes a step of providing an alkaline granular material having one or more alkaline earth metal silicate phases. The method includes a step of compacting the granular material to obtain a compact of the granular material. The porosity of the compact is smaller than or equal to 37% by volume. The intrinsic permeability of the compact is at least 1·10−12 cm2. The method also includes a reacting step arranged to form at least 5% by weight of carbonates (CO32−), by reacting the granular material with carbon dioxide in the presence of water, thus transforming the compact into the article. In the reacting step, the compact, being unsaturated with moisture at the beginning of the reacting step, is brought in an atmosphere having carbon dioxide. The atmosphere is at a temperature of at least 70° C. and at a pressure of at least 0.5 MPa. The pressure is also higher than the saturated vapor pressure of water at the temperature. As a result, at least a portion of the carbonates are formed by reaction of the one or more alkaline earth metal silicate phases. Articles are also obtained by the method.

摘要： Disclosed is a heavyweight concrete composition using slag byproducts, including: ground granulated blast furnace slag; slow-cooled electric-arc-furnace oxidizing slag or atomized steel slag used as a fine aggregate; a coarse aggregate; water; and a chemical admixture based on 100 parts by weight high-early-strength cement. Thus, the heavyweight concrete composition contains a large quantity of steel slag and blast-furnace slag that are byproducts in iron-making and steel-making processes, thereby remarkably reducing an amount of emission of carbon dioxide and maximizing the recycling of waste resources for preserving the natural environment. As a result, an eco-friendly heavyweight concrete product can be made.

摘要： The present invention relates to a process for producing a granular material 26 for mixing with at least a hydraulic binding agent and with water to produce mortar or concrete. This process comprises at least an aggregation step and a carbonation step. In the aggregation step, steel slag particles from at least a fine fraction 24 of steel slag, in particular a fine fraction of steel slag containing a significant amount of γ-dicalcium silicate, are aggregated into larger grains so as to form a coarser granular material 25. In the carbonation step, said aggregated particles in said coarser granular material 25 are carbonated by means of carbon dioxide so as to produce a carbonated granular material 26. The present invention also relates to a carbonated granular material of aggregated steel slag particles containing a significant amount of γ-dicalcium silicate, in particular at least 3 wt. %, preferably at least 5 wt. % and more preferably at least 7 wt. %, and bound within each grain by a solid matrix containing at least calcium and/or magnesium carbonates.
