	Troweled side has 1/8" less concrete on mesh		Troweled side has 1/8" less concrete on mesh


	'''Conclusions'''		'''Conclusions'''

	Both panels survived psi ratings for tank design (3.44 psi), however because troweled side has less concrete, it is a weaker side of panel in compression. Suggest using formed side as inside of tank, so that the troweled side will be in greater tension (more mesh, less concrete).

	Panel 2 with 2 layers of mesh seem to be stronger in all tests.		Panel 2 with 2 layers of mesh seem to be stronger in all tests.

	I think these would do just fine as roof tiles or panels, especially if shaped to take advantage of concrete's compression strength. For a water tank, although they survived the psi required for an 8ft tall tank, I think more testing is required.
