To provide a cement based composition in which a pseudo polymer is formed in a homogeneous state, and also, values regarding viscosity, fluidity, underwater non-separability, air quantity and material separation resistance are high.
Disclosed is a cement based composition obtained by mixing: a binder composed of cement and expansion material powder; a thickener composed of first powder consisting of a first water soluble low molecular compound selected from cationic surfactants and second powder consisting of a second water soluble low molecular compound selected from anionic aromatic compounds; a fine aggregate; cement admixture powder; and water, and in which unit water quantity lies in the range of 380.0 to 445.0 kg/m3, the ratio between the water and binder (W/B) lies in the range of 34.0 to 56.0%, the total of the quantity of the first powder and the quantity of the second powder (Vt using quantity) lies in the range of 2.70 to 4.00 kg/m3, and the quantity of the cement admixture powder (SP using quantity) lies in the range of 0.70 to 1.75 kg/m3.
