The Role of Lightweight Aggregates in Reducing Structural Dead Load

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 […]

Engineering Considerations for Using CityMix® in Lightweight Concrete Applications

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

Vibration Stability in EPS-Enhanced Lightweight Concrete

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
