Abstract：The sandwich concrete is formed by casting non-vibration concrete(50%, the surplus rate is1.4) containing large quantity of fly ash into Dipy construction formwork. The study shows that Dipyformwork can increase the compressive strength of concrete markedly which can reach the grade ofcompressive strength at the ages of 14 to 20 days, and its compressive strength at the age of 56 days is1.2～2.0 times the designed strength.
