EPS is one of the lightest weight materials out there, yet historically it has struggled as an concrete aggregate. That is because, in many lightweight concrete mixes, traditional EPS beads present a recurring challenge – specifically, a phenomenon called “popcorning.” Popcorning occurs when uncoated EPS separates from the cement paste during mixing or curing, migrating […]

In many concrete applications – especially multi-story buildings, large-span structures, and precast components – the weight of the material itself is one of the most important engineering concerns. Concrete is heavy, and yet it is often the best choice for not only structural elements, but also flooring and décor. That means that architects typically have

The lighter the concrete, the easier the application and the more desirable the product – provided, of course, it does not reduce concrete’s durability, structure, or appearance. Historically, the use of lightweight aggregates has presented challenges related to moisture absorption, batch consistency, and variable compressive strength results. That is where CityMix comes in. CityMix has

Concrete product manufacturers want to make their products lighter. The lighter the weight, the more popular the product, as they’re easier to install, easier to ship, and more. Yet lightweight concrete formulations often face a significant performance challenge: instability during vibration. When standard lightweight aggregates are introduced into a mix, they can separate from the

Concrete products that are lighter weight are both easier to install and cheaper to create. If these products can be created without substantial loss to strength or longevity, then there is no reason not to use a concrete additive in all of your projects. That’s what you get with CityMix. CityMix provides an innovative lightweight
