Rebar-free prestressed concrete and forming method therefor

Abstract

The present disclosure relates to an rebar-free prestressed concrete and a forming method therefor. The unreinforced prestressed concrete includes: a base layer, which is a mortar, concrete or neat paste pouring piece, where the base layer has a deformation value S1; and a prestressed layer disposed on a surface of the base layer and completely covering the base layer. The prestressed layer is a mortar, concrete or neat paste pouring piece, and does not include a steel bar. The prestressed layer has a deformation value S2, where S1 is smaller than S2. The solved technical problem is how to achieve an unreinforced prestressed concrete having a prestressed surface layer without the use of steel bar 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.
