Project Details

ELEMIX enabled Kienstra/American Ready Mix to meet the design challenge of using a pumpable structural mix of 3000 psi with a maximum dry unit weight of 105.0, while being finisher-friendly. Normal lightweight concrete could not meet these specifications. The overall consistency of slump, pumpability, unit weight, strength and finishability of ELEMIX facilitated concrete that meets these stringent requirements.

This is one of the longest distances that lightweight concrete has been successfully pumped, placed and finished. ELEMIX provided the developers with increased efficiencies with easy placement, pumping and finishing while reducing building and transportation costs. Six pounds of ELEMIX replaced approximately two cubic feet of fine aggregate, facilitating less dependence on geographically-specific natural materials. River City Casino received the Quality Concrete Award from The Concrete Council.

SYNTHEON ELEMIX concrete additive is an engineered Lightweight Synthetic Particle (LSP) that dramatically and uniformly reduces the weight of concrete without requiring air-entraining admixtures. ELEMIX leverages its dynamic structure and dispersion characteristics to become an integral part of the concrete matrix, resulting in reliable consistency and improved performance for lightweight structural concrete. Used in combination with or as a replacement for normal weight and lightweight aggregates, ELEMIX achieves ICC-ES AC-408 code compliance. It enables builders to produce concrete that reduces construction costs, resists cracking, and pumps, places and finishes easily. By reducing a building’s dead load, there is a reduction in the amount of steel required to support the building. This equates to a total reduction in cost of materials for the project and the time it takes to build. ELEMIX is revolutionizing the time and cost of building projects by revolutionizing science behind the concrete matrix.
