Title:
REBAR-FREE PRESTRESSED CONCRETE AND FORMING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/213335
Kind Code:
A1
Abstract:
The present invention relates to rebar-free prestressed concrete and to a forming method therefor. The rebar-free prestressed concrete comprises: a base layer which is a mortar, concrete or neat slurry pouring piece; the base layer has a deformation value S1; a prestressed layer which is disposed on the surface of the base layer and completely covers the base layer; the prestressed layer is a mortar, concrete or neat slurry pouring piece, and does not comprise rebar; the prestressed layer has a deformation value S2, wherein S1 is smaller than S2. The solved technical problem is how to achieve a rebar-free prestressed concrete having a prestressed surface layer without the use of rebar tensionsing, allowing same to improve the crack resistance and durability of a building without increasing new investment, reducing construction costs without bringing about fire hazards, and thus improving suitability for practical use.
