PROCESS FOR TRANSPORTATION OF A HYDRAULIC COMPOSITION

摘要

The invention relates to a method for transporting a fresh hydraulic composition comprising: 220 to 500 kg of a hydraulic binder including Portland cement, per cubic metre of the fresh hydraulic composition; 400 to 1200 kg of sand, per cubic metre of the fresh hydraulic composition; 150 to 1000 kg of gravel, per cubic metre of the fresh hydraulic composition; 0.05 to 5 % dry weight of a superplasticiser, in relation to the weight of the hydraulic binder; and 0.01 to 0.5 % dry weight of a rheology modifier, in relation to the weight of the hydraulic binder, the transportation taking longer than ten minutes without the hydraulic composition being stirred.
