Abstract
New experimental researches of strengthening by increase in cross-section section in the compressed zone additional concrete of two-way slabs are shown. Character of formation of cracks strengthened by escalating from the top side of reinforced plates, supported on the contour is experimentally established, including at strengthening under loading. New experimental data about durability of two-way slabs, strengthened by escalating of concrete of the compressed zone are received. The analysis of the received experimental data has shown the efficiency of strengthening by escalating of concrete of the compressed zone of two-way slabs.
