Strength of the monolithic coverings with non-fixable formwork of steel fibro-tuffcrete elements

The article presents the strength study results of the tuffcrete flexible monolithic structures with fixed formwork, combined reinforced rods and fibers. The nature and degree of the fibers percentage influence in the tuffcrete element of the fixed formwork, the dimensions of the fixed formwork elements’ fiber-reinforced section and the strength of monolithic tuffcrete on the normal strength to the longitudinal axis of the monolithic combined-reinforced bending floor structures, as well as on the adhesion strength of the fixed form contact line with concrete monolithic, are analyzed. The experimental dependences that make it possible to more economically design the structures under consideration, taking into account the strength and quantity parameters, as well as the geometric dimensions of their individual components, are proposed.
