Abstract
The present invention provides structure protection sheets which can not only dramatically reduce a construction period to place protective layers on surfaces of structures such as concrete but also protect structures for a long time. The present invention relates to a structure protection sheet, including: a polymer cement layer on a side facing a structure; and a resin layer on the polymer cement layer, the structure protection sheet having a thickness distribution of not more than ±100 μm.
Claims9
A structure protection sheet, comprising:
- a polymer cement layer on a side facing a structure;
- and
- a resin layer on the polymer cement layer,
- the structure protection sheet having a thickness distribution of not more than ±100 μm.
A method for producing a precast member, the method comprising:
- placing a structure protection sheet on an inner surface of a molding frame;
- and
- then pouring a concrete formation composition into the molding frame to produce a precast member,
- wherein the precast member comprises the structure protection sheet on a portion or the entirety of its surface,
- the structure protection sheet comprises a polymer cement layer and a resin layer on the polymer cement layer, and
- the structure protection sheet has a thickness distribution of not more than ±100 μm.
