Measuring the unintended impact of chemical curing agents, bond breakers, and densifiers on concrete surface free energy.
Tilt projects can be a series of conflicting goals. Maybe none more prevalent then the pursuit of a perfect concrete slab for casting beautiful panels and using adhesives to bond forming materials. Building owners want tight, densified concrete slabs and tilt-contractors want to get the project moving minimizing steps and slab curing times. So, as an industry we have turned to chemicals to get the job done. Densifiers are more prevalent and bond breakers are being used as curing compounds. Unfortunately, both of these solutions negatively impact the concrete’s surface free energy, in other words “it makes the glue not work.”
Over the last year, GluDown has been researching ways to accurately measure concrete slab surface free energy, identify potential challenges from these measurements, and provide corrective actions for glue down job success. We will present these findings to the TCA to open the industry’s eyes to this challenge, hopefully generate discussion on how to use this information, and ultimately create specifications which will better tilt-up forming practices.
At Innovative Structural Solutions (INNSTRUCT) we have developed the Total Integrated Panel System (TIPS), a technology and process that acts as the primary structural and insulating member in conventional tilt-up construction. TIPS sets 4" of expanded polystyrene between 2 layers of welded wire mesh fabric. These are then joined together by diagonal truss wires. Because of the extreme strength of this pyramidal system, TIPS walls can be built with as little as 5" of total concrete in a 9" insulated tilt-up panel. The system reduces the amount of added rebar by 60-90% and concrete material by 30-50%, depending on the panel design. This drastic reduction in materials, along with the incredible strength of our system, creates a panel that is up to 50% lighter and much easier to work with than traditional tilt-up methods.?

Our team has been in the architectural precast / pre-stressed business for over 40 years. During that time we have made insulated wall panels using every system. We understand which designs work and more importantly which do NOT work for various reasons including; design code, production efficiency and engineering requirements.

We have always looked at tilt-wall as an evolving artform. There are many things that we considered pushing the envelope a decade or two ago that are now commonplace or outdated. At Seretta, we take our role as an industry leader seriously and are constantly looking for and trying out potentially new and better ways to perform our work. We know that if you become complacent, you will become outdated. At Seretta, we use only the latest and most advanced chemicals, equipment, software, methodologies and technologies so that we continue to produce the highest quality work in the shortest amount of time.
