Abstract
The present invention relates to a concrete construction that comprises a concrete slab and a ductile strip adjacent the slab. The ductile strip comprises an engineered cementitious composite of cementitious material and reinforcing fibers with the ductile strip being directly bonded to the slab. The present invention also relates to a method of making or repairing a concrete construction, the method comprises providing a ductile strip adjacent a concrete slab, wherein the ductile strip is made of an engineered cementitious composite comprising cementitious material and hydrophilic and/or hydrophobic reinforcing fibers. The present invention further relates to a roadbed or building floors suitable for vehicular traffic, the roadbed comprises a plurality of slabs and ductile strips comprising an engineered cementitious composite of cementitious material and reinforcing fibers.
