Plastering Armature2806 viewsAvelino and Zane plastering and Doug Smith stirring the mix. The bench details did not slow the guys down much.

Nicho Armature1861 viewsThis is an example of a Nicho with recessed electrical for lamp.

Strong Corner2363 viewsThese shorter stretches of wall needed no exterior supports because of the supporting corner and short spans of straight wall.

Doug Lacy window & wall fill photos3415 viewsUpper Left -- This picture illustrates many phases at one time. A tarp was placed over the armature to protect thin shell cement from wind and sun for a better control of curing conditions. The sculpted windows were just mudded in and I was still formulating a mix and plan that would help the plaster stick over head which is why you see the hose attached to the inside of the arch. This hose was used as a screed point for the first few bands of concrete so the exact thickness could be gauged with some precision for the rest of the hand applied cement.

Upper Right -- This is just after the inside shell overhead plastering was complete. Fluffling the mix with the expanded Mearlcell 3132 a little made this overhead plastering stick without comprimising the strength of the shell. These seashell slice windows represent part of the Healing and Evolutionary Architecture theme I wanted to demonstrate in this home.

Lower Left -- This is the inside of the wall after I began filling it with cellular concrete.

Nicho3229 viewsThese Nicho's Provided stability but it should not be assumed that plastering the underside of these is quick and easy for a plaster crew. The topside portion of these details should be plastered by reaching inside the wall through an opening.

Start of Wall with Tirrolessa2485 viewsSpraying the wall with the hopper sprayer turned out to be difficult with the ultra low water mix design (0.23 water/cement ratio). The mix became too hard to smooth just after a pass was made. The air flowing past the mix seem to cause it to set up immediately. Plastering by hand seemed easier with this mix.

park glass wall.jpg
Fluid Shape2855 viewsThis wall was filled with 25 tons of glass before the surface shells were applied. The nice distortions on the surface were caused by heavy glass getting stuck on the remesh blocks that were layed in laterally instead of vertically. The lateral blocks restricted the size of the openings for the glass to fall and the armature bowed outward under the weight because their were long horizontal runs that had no cross tension supports. All good though. This wall is now the focus of a big mural project.Jul 12, 2006
