Dick,
We are using Type I. There is no coarse aggregate in the mix - only sand. Unfortunately, I have little knowledge of what others are using in similar applications. Our plant will be set up in the Caribbean, and I anticipate only running the mixer one shift per day. Your input on the...
The options that exist for pre-cast, wet processes include A) horizontal shaft, B) pan and C) planetary style mixers. The cost of these options increase from A) to C). Our application is a low-density (65 pcf) mix that has a need to fold cellular foam into the mix at the last step. When...
Thanks for the replies. Yes, the tensile strength is more important. The mold is cast horizontally in a twin configuration. It is supported during breakout, and three of four sides are removed. There will be some stress pulling the unit laterally from the fourth side. However, the greatest...
We have a cellular, foam entrained mix for a pre-cast panel application that has about 45-55% air by volume. Ultimate strengths needed are 1200-1500 psi, and we can hit 550 psi within 24 hrs. At what strength can we effectively break out product from the molds? This can obviously be verified...
