according to go together with a ratio. The concrete pump transports line to adopt a heat preservation, and increase agitation time of concrete, is raised into 90~ by the original 60 ses 100 ses. The concrete surface after sprinkling to build to accept water overaly the 1 F plastics cloth first, then add to cover the 2 F grass bag a heat preservation to protect 3~ 7 ds. Measure in time after in advance sprinkling to build part to establish to measure Wen Kong, carving to build, promise that the concrete goes into a mold to be no lower than 5 ℃. Use the Peng cloth overlay raw materials, such as sand and pebble...etc. on rain snow sky, in order to prevent the material appears jelly piece and snow regiment. The concrete protects:Protect ascent concrete, the adoption heat preservation material overlay protects, stake body concrete because of at underground, And the temperature is higher, have more beneficial condition to the concrete's protecting, only overaly a stake fluently grass Lian son to carry on a heat preservation to keep Protect. 57 to build engineering Carve to build the material cleans up accumulated snow, ice frost clean before carving to build, the lime cream avoids being frozen whole subjected to a jelly but dehydrate breeze Lime cream of turning forbids an to make the sand that the sand syrup is used, don't contain a jelly piece
