Welcome to the Energy Tech Systems Epoxy Grout Shootout! We tested some of the top epoxy grouts on the market so that you can make the right decision on your next machine grouting project.

Epoxy grout is a three-part formulation consisting of the following: Part A – Resin, Part B – Hardener and Part C – Aggregate.

The epoxy grouts tested were:

Epoxy grout products ready for testing
Epoxy grouts tested were Chockfast Versaflow, Chockfast Red, FasTrac CE815, Five Star DP, and Masterflow 648.

Each epoxy grout was tested using the following ASTM Standards:

ASTM C1339 Flow box to test flowability and effective bearing area.

ASTM C579 Method B, Load Rate II

For 3- and 7-day compressive strength using plastic cube forms.

ASTM D2471 To measure peak exotherm.

A sample of each epoxy grout was mixed according to ASTM recommended method at an average material & ambient temperature of 82 degrees Fahrenheit.

The flow box was set at a 2” depth and the epoxy grout mix was then poured into the flow box hopper. After waiting 5 minutes, the flow box gate was lifted, allowing the grout to flow through the trough. As soon as the grout contacted the backplate, the time was recorded. The faster the time, the higher the rate of flow.

What are the results?

The following video shows a side-by-side comparison of the flow box test in real time.

The following chart shows the flow box times, peak exothermic temperature, and compressive strength.

What are the takeaways?

The fastest Flow Box Times were achieved by Chockfast Versaflow (10.25), FasTrac CE815 (10.45), and Five Star DP (26.62). The Versaflow and CE815 times are incredibly close! They are off by 0.2sec and within the margin of error. We look forward to running this test again in the future to determine if the results remain the same.

For 3-Day Compressive Strength, the top performers were Masterbuilder 648 (14,106), FasTrac CE815 (13,456), and Chockfast Red (13,245).

For 7-Day Compressive Strength, the top performers were Masterbuilder 648 (15,629), Five Star DP (14,485), and Chockfast Red (14,200).

The FasTrac CE815 put up some impressive numbers. FasTrac CE815 offers the speed of Chockfast Versaflow and the strength of Chockfast Red, at a significantly reduced price. We've just found our new favorite machine grout! If your project requires an epoxy grout with excellent flowability, high early strength, deep pour capability, and a high effective bearing area, then you owe it to yourself to give FasTrac a try. You won't be disappointed.
