Abstract：Based on the specialties of concrete for pavement which require objectively the compatibility high anti-crack and earlier solidification, and in addition, the mechanism of vacuum dehydration technology which may render the concrete compact are earlier solidified, therefore, combined with the construction practices, the vacuum dehydration treating technology was adopted in construction of concrete pavement plate for the Ertan Power Station, The earlier solidification mechanism on concrete by using vacuum dehydration technology in based mainly on: (1)the principle of solidification by compaction, (2)the change regularity on transmission of the degree of vacuum. The main construction procedures of vacuum treated concrete arc: (1) the selection of mixture ratio, (2) the implementation of vacuum dehydration technology, (3) the prevention of initial cracks. Although the vacuum treated concrete has the earlier solidification compatibility, high anti-crack and wear resisting properties but due to the uneven of vacuum transmission, the final utilization effect of the concrete should be resolved through further researches.
