special concrete construction

This method has some special features such as saving of time and space, reducing the amount of field pouring of concrete and shortening construction period.

该法具有省时、省地、减少现浇混凝土施工量及缩短施工工期等特点。

Many concrete engineerings ceased in long period appeared corrosion phenomenon, so, before stop construction, some protection measures should be taken for special place.

长期停建的混凝土工程多有钢筋锈蚀现象，停工前应对特殊部位预先采取防护措施。

The objective of this paper is to explore the solution to the design of special concrete against radiation and measures to the construction.

为解决防辐射的屏蔽重混凝土的配合比设计和重混凝土的施工技术措施，现就针对上述两问题的解决方法和技术措施做一探讨。
