HYDRAULIC COMPOSITION AND CONCRETE STRUCTURE
To provide a hydraulic composition having excellent workability, the composition including air-entraining properties when a porous carbon material such as biochar is included in a hydraulic composition, such as a concrete composition.SOLUTION: A hydraulic composition according to an embodiment of the present invention comprises a carbon material, a hydraulic material, and a chemical admixture as a cement dispersing agent. The carbon material has a specific surface area of 100 to 1000 m2/g, and a bulk density of greater than 0.05 g/ml, and further has 50 mass% or less of particles having a particle size of 53 μm or less. The chemical admixture contains a compound having an acid group and a polyalkylene glycol chain. In addition, the chemical admixture also contains a polymer compound containing a sulfonic acid group and/or salt thereof.SELECTED DRAWING: Figure 1
