Making Lightweight Concrete

CityMix is an extraordinarily lightweight, durable and user-friendly material suitable for blending in a wide variety of concrete, stucco and masonry products. The technology allows varying portions of the heavy sands and gravels common to cement-based mixtures to be replaced with ultra-lightweight CityMix material in order to reduce overall product weight. And since CityMix weighs approximately 3 lbs per cubic foot, even a modest ingredient volume substitution for typically 90-100 lbs per cubic foot conventional fine aggregates can produce a significant weight reduction. This concrete mix is perfect for use in artisan concrete creations, slabs, furniture, and for use as concrete countertop mix.

Resilient Strength

CityMix also helps enhance certain desirable cement-based product performance characteristics such as flexibility, resilience, freeze-thaw durability, water repellency and crack resistance. The material is composed of approximately 99% pure recycled waste (by volume), thereby creating – to the best of CityMix’s knowledge – the "greenest" and most lightweight additive ever made commercially available for use in concrete products.

Saving On Shipping

The percentage of CityMix ultra-lightweight synthetic aggregate that may be substituted in any given concrete mixture is fully customizable, so CityMix can serve as a suitable weight-reducing material for a wide variety of both structural and non-structural applications. For example, a structural concrete building panel might only be able to be reduced 5% in weight and still retain its minimum code or engineering requirements, but common non-structural objects like landscape blocks, parking curbs or statuary, for example, might be reduced in weight by as much as 70% and still be fully acceptable for their intended purposes. But regardless of the degree to which any particular product might most effectively incorporate CityMix, the market demand for high-performing, economical, and "green" lightweight concrete products that can dramatically reduce shipping, handling, installation and overall building construction costs is virtually limitless.
