A concrete composition and method include a portion of fine aggregate bearing a coating of a polymer or an admixture, which may be a continuous coating layer or a layer of powdered, discrete particles embedded in a binder. The polymeric coating may be an admixture in powdered form, a super absorbent polymer (insoluble in water, but absorbing water), or another polymer such as the acrylamides, co-polymers thereof, polyacrylamides, or the like (soluble in water). The coating absorbs water, but particles are too small to form significant voids. Water is absorbed into the concrete mix in far greater proportions (e.g. w/c ratio over 0.5) improving workability, doubling workability time, and improving ultimate compressive stress (strength).

The invention relates to a cable robot for creating a structure or manipulating a workpiece, comprising a working head which is suspended on a support structure having at least three support columns by a system of cables having at least three control cables, wherein cable winches are provided for adjusting the control cables relative to the support structure and/or relative to the working head, and they can be actuated by an electronic control device for moving the working head, wherein the support columns of the support structure are luffingly and/or telescopically arranged on a revolving stage, which has a ballast weight for absorbing a tilting moment introduced into the respective support column by the system of cables and which is arranged on an undercarriage such that it can rotate about an upright revolving stage axis, said undercarriage having a chassis and being configured such that it can move with the revolving stage and the downwardly luffing and/or retracted support column.

A 3-dimensional printed structure, and a system and method for the 3-dimensional printing of structures is disclosed, including a structure comprising a plurality of sides comprising the following: a bottom, a top, a left wall and a right wall each constructed using a 3D printing process. The structure is 3D printed by initially printing a continuous rear end surface associated with each of the bottom, the top, the left wall and the right wall and thereafter the 3D printing process additively depositing material in a continuous bead to build up the initially deposited material to further construct the bottom, the top, the left wall and the right wall to complete the 3-D printing of the structure. The 3-D printing process finally deposits the material to form a monolithic and continuous front end surface associated with each of the bottom, the top, the left wall, and the right wall, wherein the 3-D printed structure is rotated to rest on the bottom upon completion of the 3D printing process.
