Ferrocement is an art form of tension and compression, blending advantages of stone and metal into imaginative, cost effective structure. (Structural plastics and many other additives are also finding their way into artful composites based on cements.) Here are some pictures of what became imaginatively possible.

Quick, "how to solve models" via the www is offered freely as a public service, where possible, just ask! (As time permits). Reasonable rates for highly customized, computer-accurate, 3D modeling. High resolution graphics and plans made to order.

Camera Lucida: This secret of the masters should work beautifully for sculptural concrete and ferrocement.

While scalloping uses more surface area, it also engenders a framing component. Shells are reinforced by the surface corrugation. More surface can mean more labor and material, but it does offer some strength advantages. Our world is improving tools to simplify curvilinear construction. It remains for individuals to support those efforts and "vote with the pocket book". Note: These pages are placed in the public domain and are furnished "as is".

Here is a vault frame which can be made of reinforced concrete rings as framework. Clickhere for related idea.

Several more examples in this series follow below...

Next (above), is a sea shell like cage design possibility. CAD, (design software) allows sculptors to access a wide array of geometrical tools to determine difficult reinforcement configurations and to develop methods for actual construction. Here is a link to ring reinforcement as a means to build highly curved structures. Although reinforcement rings are not easily- commercially available, a "one man" approach to study feasibility of rings is under way, slow but sure. Follow links on this website for much more on ring reinforcement and on single person methods for construction, (where hired labor cannot be afforded).
Next above is my effort with new software tools to explore curved geometry. More can be seen, click here.
Next (above), is a "castle shape" applied to tilt up concrete construction. Wall sections are shown which can be sand molded on the ground. Each undulation in the walls serves much like corrugation in card board, which produce a "space frame" to compound strength in a manner similar to studs in a wooden wall. These undulations also serve to stabilize the wall sections as thy are raised into place.

Above is a preliminary drawing for tilt up arch sections, (better drawings to follow).

In this purely hypothetical CAD model each arch has most surfaces at 1" thick with a gusset extending along the whole curved portion of arch, (itself 1" thick). All large surfaces have a slight ribbing to add strength at joining edges. The main span is 20 ft. Total wall/roof volume of each is about 9 cu ft., so wt is about 1170 lbs. If the straight wall sections are separated and poured flat on the ground, and also if the curved parts are poured on a sand pile/ mold... and all these are poured in one or two sessions, then ready mix might be used. Sand casting methods from ancient tech apply. A backhoe could be used to lift all pieces into place, (if safely managed by responsible operators). Is there a cement mix which will hold up during assembly and over life? Adding more weight would require a bigger backhoe and stronger safety measures.The total for a 20 X 20 ft building with wall at back, garage door openings at front could be as little as 120 cu ft., per inch of thickness.

Domes next....

Above is a basket weave , great circle, lamella cage, mostly in yellow. The green members show the relationship between the 2 angles used for weaving together the reinforcement members. The scale becomes important in visualization when doors and windows are cut out of a CAD model.

Referring to CAD data in the dome model above: about 20 ft diameter, with a slight extension out the front. For each inch of thickness, volume is near 88 cu ft., depending on details. (The top includes a 5 ft diameter sky light hole. The dome encloses minimal floor space, but will hold 2 reasonable vehicles.

A mason friend of mine who lives on a State highway, realized that cement sculpture was a hot business and quickly developed his own style differing from my sand molding. He casts oversized rough shapes and then carves the pre-hardened cement. (Click here to visit his site). Also I notice through the internet that variations of cement sculpture are catching on, through out America. I would like to add more www links to this page if you wish to share your sculptural work methods.

Searching Synergy ........ Free Exchange of Ideas

Enersearch was incorporated in 1980 but never materialized financially.  A  synergy of concepts were developed and are reflected in the pages of this series.  The synergy continues as a single handed effort of Bo Atkinson, in Maine, USA.
