Abstract:
1. A method of producing a microreinforced concrete member for erection of loaded and/or impervious structures, the method comprising the steps of: a) arranging at least three mesh layers on top one another and securing the at least three mesh layers spaced apart relative to one another to form a three-dimensional mat system having a mesh arrangement that is preselected based on desired performance properties of the concrete member such that a mesh width of the mesh arrangement of the three-dimensional mat system decreases at least in a direction perpendicular to a face of the at least three mesh layers; b) subsequently, infiltrating a slurry containing first aggregate in an infiltration direction from a largest mesh width to a smallest mesh width into the three-dimensional mat system and positioning the first aggregate according to decreasing aggregate size in said infiltration direction at preselected locations within the three-dimensional mat system in accordance with the desired performance properties, wherein the preselected locations are determined by the mesh arrangement.
