RussTech incorporates only the highest quality raw materials that are available and has in-place a comprehensive quality assurance program that guarantees consistently high-performing admixtures. Each raw material is screened when it enters the plant and is tested for solids level, pH, and specific gravity. Before each finished product leaves the reactor/mixing vessel, it is screened for the highest consistency and performance using the latest technology in evaluating chemical admixtures. Our lab coefficient of variation consistently exceeds an "excellent" rating based on ASTM Laboratory specifications.
