City Mix Lightweight Concrete Additive 100 L

City Mix Lightweight Concrete Additive 100 L 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 1.3kg per .9 sqm, even a modest ingredient volume substitution for typically 40-45 kg per 1 sqm conventional fine aggregates can produce a significant weight reduction.

City Mix Lightweight Concrete Additive 100 L 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.

The percentage of CityMix ultra-lightweight synthetic aggregate that may be substituted in any given concrete mixture is fully customisable, 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.

Non-Structural and Decorative PreCast

CityMix is used in a wide variety of non-structural precast products, including architectural shapes, statuary, fireplace surrounds and landscape blocks. CityMix technical experts have helped many manufacturers to optimise weight reduction ratios for their mix designs, while still maintaining critical compressive strengths, cure rates and other vital performance requirements.

Structural Precast

CityMix has successfully completed all ICC performance tests and is now report-pending for use in full structural concrete. CityMix has already been commercialised in such items as 41MPa highway sound panels (at 15% weight reduction), a variety of engineered wall cladding elements, concrete fence posts and other structural products seeking to reduce shipping, handling and attachment weight.
