Technical Data Sheet Declaration Of Performances Description Chryso®Quantec SE‑507 is a specialised admixture developed for concrete mixes with very low water content, where high accuracy and consistency in the manufacturing process are required. It is designed to enhance dimensional stability, surface finish, and structural uniformity in low‑slump and semi‑dry concrete applications. Formulated from a blend of carboxylated polyethers and synthetic surfactants, Chryso®Quantec SE‑507 improves cement hydration and strength development without loss of cohesion. In optimised systems, its use can deliver strength increases of up to 20% at equivalent cement content. The product is manufactured under controlled conditions to ensure consistent performance. Application areas Chryso®Quantec SE‑507 is suitable for: Concrete blocks (natural, lightweight, or artificial aggregates) Static and mobile block‑making systems Air‑cured, steam‑cured, and autoclaved products Concrete brick presses Paving block production Extruded concrete Concrete tile manufacture Low‑workability concrete systems using vibro‑compression or press technologies Chryso®Quantec SE‑507 can be used with: All types of Portland cement Cement replacement materials For use with special cements, consultation with Chryso Technical Services is recommended. Chryso®Quantec SE‑507 must not be premixed with other admixtures. The presence of other chemical admixtures may affect performance. Consultation with Chryso Technical Services is recommended when combined systems are considered. Benefits Improves surface texture and finish Enhances cohesion of low‑workability concrete mixes Improves workability and compaction Provides better dimensional stability during production Increases compressive strength (typically 20–40%) Reduces cracking and shrinkage Minimises product waste Supports full cement hydration Packaging Drum 205L Bulk delivery on request
