摘要： A concrete composition includes a hydraulic binder, wherein the hydraulic binder includes Portland clinker and mineral addition including limestone, or fly ash or combination thereof, the limestone and/or fly ash representing at least 50% by weight of the total weight of the binder; a cationic polymer having a cationic charge density greater than 0.5 meq/g, and an intrinsic viscosity less than 1 dl/g; a water-reducing additive comprising at least one phosphonic amino-alkylene group; aggregates, and water.

摘要： A method of placing a flowable construction material including a hydraulic binder for building structural components layer-by-layer, such as for 3D concrete printing, the method including preparing a fresh flowable construction material made of Portland cement, fine limestone filler materials, fine sands, water, and water reducing admixture and possibly a set or hardening accelerating admixture, conveying the flowable construction material to a deposition head, placing the construction material through an outlet of the deposition head in order to form a layer of construction material, before placing the construction material, adding a rheology-modifying agent to the construction material so that the placed material has an increased yield stress when compared to the material during the conveying step.
