PROBLEM TO BE SOLVED: To provide concrete, mortar and paste used as a building material and a secondary product material, which have high viscosity and fluidity, and have excellent resistance to separation of aggregate, cement and water. Provided is a hydraulic composition having properties and not requiring compaction by vibration of a vibrator or the like. SOLUTION: The adsorption characteristic to cement is 10%. Less than water-soluble polymer (a-1), water-soluble polymer with an adsorption rate of 10% or more to cement (a-2), high-performance water reducing agent (b), hydraulic powder (c) And a water (d). |
