How to prevent blackening of concrete surface |
| abstract |
(57) [Abstract] [Purpose] The present invention provides a dispersing effect of a cement dispersant when concrete is poured using fresh concrete containing silica fume and / or fly ash and a cement dispersant. It is intended to provide a method capable of preventing blackening of the concrete surface of the concrete without damaging it and without adverse effects such as retardation of setting and reduction of compressive strength. According to the present invention, when pouring concrete using fresh concrete containing silica fume and / or fly ash and a dispersant for cement, an amine compound represented by the following formula 1 is added to the fresh concrete. The present invention relates to a method for preventing blackening of a concrete surface of a concrete. [Formula 1] [In Formula 1, R 1 : an alkyl group or an alkenyl group having 8 to 22 carbon atoms R 2 : a hydrogen atom or a hydroxyethyl group n: 1 or 2] |
