| Abstract: | As all the constructors use the ready-mixed concrete for the first time,we make the low and medium intensity fly ash pump concrete using the 42.5R cement,we studied a series of experiments on the factors of the raw materials,mixture ratio,construction technology and the weather,we have found the main factors influnced on the board shrinking crack. |

| Keywords: | low and medium intensity fly ash pump concrete plastic shrinking crack wipe the surface many times weather |
