Abstract

The present invention relates to a fresh concrete composition comprising at least: i) a hydraulic binder comprising:—from 20% to 40% by weight of Portland cement clinker based on the total weight of said binder, —from 45% to 75% by weight of filler based on the total weight of said binder, and—from 5% to 15% by weight of material of ultrafine particle size based on the total weight of said binder, selected from hydraulic additives, pozzolanic additives, ultrafine cements and mixtures thereof, ii) at least one superplasticiser or plasticiser, iii) water, and iv) aggregates.

Abstract

Method for manufacturing a concrete from activated slag, comprising at least the steps consisting of: a) arranging a premixture P of water and granulates, the temperature of the premixture P being at least equal to 10° C., b) arranging an activation system A comprising at least a co-binder, a chelating agent, an alkali metal carbonate and a carbonated material different from the alkali metal carbonate, c) incorporating the activation system A and a slag S by mixing them into the premixture P, the activation system A and slag S being introduced successively and/or simultaneously, d) continuing the mixing until a fresh concrete is obtained, and e) allowing the fresh concrete to cure.
