混凝土浇注 meaning in English
concrete depositing
concrete placement
concrete pouring
Examples
- If the surface is covered or watered after casting of concrete , the influence resulted from change of environmental temperature and relative humidity on concrete will decrease to some extent . then the shrinkage stress will also decrease and the probability of cracking will be reduced as well
混凝土浇注完后对表面进行覆盖或浇水养护，可以很大程度上地减少外界温湿度变化对混凝土内部的影响，减小了混凝土的收缩应力，从而降低混凝土开裂的可能性。 - According to the multi - areas development strategy , the corporation has expanded its business to engineering and construction of all kinds of civil works , municipal and public works , marine works , dredging and reclamation works as well as manufacture and installation of hydraulic steelworks and electro - mechanical equipment , with the major annual capacity of 150 million m3 in earth and rock works , 15 million m3 in concrete production and placement , 10 , 000 mw in installation of generating units , and 150 , 000 tons in manufacture and erection of hydraulic steelworks
