Abstract (en)
[origin: EP2050729A1] An aggregate construction material e.g. concrete incorporates a powder additive that acts as a hydraulic biding agent. The powder particles have an inner layer (2) and an outer layer (3) that act as an additive. The core is cement, micro-silicate particles, light ash, cinders, organic or inorganic fibres, mineral substrate. The additive inner layer is polycarboxylate. One outer layer of the powder additive is naphtaline-sulphonate or lignine-sulphonate and/or melamine-sulphonate. Further claimed is a process to mix and prepare the aggregate construction material.
