Zusammenfassung:	PROBLEM TO BE SOLVED: To provide expansive low shrinkage cement concrete where concrete having expansibility and low dry shrinkage property with stable quality can be produced in a construction site and freely installed only at a place desired to be used.SOLUTION: In a method for producing expansive low shrinkage cement concrete, ready-mixed concrete is prepared in a ready-mixed concrete plant and a slurry being prepared with an expansion material and a non-aqueous solution and having a slurry viscosity of 0.4-9.0 Pa s is charged into an agitator vehicle, mixed and agitated after being transported to a site. 【課題】品質の安定した膨張性や低乾燥収縮性を有するコンクリートを、建設現場で製造することが可能となり、使いたい場所にだけ自在に打設することができる膨張低収縮のセメントコンクリートを提供する。【解決手段】生コンプラントでレディミクストコンクリートを調製し、現場まで搬送した後に、膨張材と非水系溶液で調製した、スラリー粘度0.4〜9.0Pa・sのスラリーを、アジテータ車に投入して混合撹拌する膨張低収縮のセメントコンクリートの製造方法である。【選択図】なし
