Thanks for visiting us at World of Concrete 2010.

The show size and attendance was down, but our visitor count was up! While visiting with all of you, we learned a lot and heard some really interesting ideas for the use of cellular concrete. We'll be sharing some of those with you in the coming weeks. Every time we exhibit we learn a lot and hope that you learn from visiting us.

If you have questions or want to talk about cellular concrete, call us at 800-553-2404 or 319-987-2976.

You may also contact us online here.

We experimented today with a modified shotcrete system. Shotcrete is using high pressure air (about 100 psi) to shoot concrete onto a surface, usually pools or walls. We had some experienced help with Dave, who has worked with it before, and Derek our new intern who has seen it done before. With our limited knowledge we forged ahead.

We had 2 goals in experimenting with shotcrete. The first was to try and figure out a method we can shoot it on our exisitng steel sided building to create a 2 hour fire rating. The second project is a shower stall and using durarock and shotcrete instead of precast concrete panels.

The first batch was mixed using 23 lb. of type 1 portland cement, 8 lb. water, 1.25 oz of super plasitizer polycarboxylite, and enough foam to acheive a finished density of 75 pcf. We sprayed this on a poly tank and a plywood wall. We are using a drywall texture gun to shoot the concrete. This stuck better than we thought but we weren't done experimenting.

The second batch we used 20 lb. of concrete and no plastizier. This didn't mix up as well and when shot had chunks of cement in it. We added sand but that didn't solve the problem. We will be doing more testing later this week.
