RHEIN-CHEMOTECHNIK GMBH - for better concrete

Liquid stabilizer for control of segregation and sedimentation of high slump concrete and Self Compacting Concrete (SCC). Significantly increases homogeniety of high high slump concrete and Self Compacting Concrete (SCC), avoids sedimentation of fines and segregation of aggregates, facilitates Self Compacting Concrete of high stability and excellent flowability.

Increase of freeze-thaw resistance, for precast elements (barrier walls, steps etc.); improvement of workability and reduced bleeding, recommended for combination with PCE-based superplasticizers. Creates a system of stable micropores of defined size and distribution in concrete; increases flexibility and improves workability.

Increase of freeze-thaw resistance, for road decks, bridge decks, and precast elements (barrier walls, steps etc.); improvement of workability and reduced bleeding, especially in concretes with low amounts of fines. Creates a system of stable micropores of defined size and distribution in concrete; increases flexibility and improves workability.

Nano-CSH based nitrate-free accelerator of hardening of the latest generation for higher strength at an early stage of hydration. Concrete and reinforced concrete in accordance with DIN EN 206-1 in conjunction with DIN 1045-2, also in prestressed concrete. Considerably quicker formwork handling in precast concrete production, significant reduction or total absence of heating measures, reduced CO2 emissions, potential savings on cement, use of cement with lower clinker content or increased proportion of cement substitutes, concreting at lower temperatures, earlier attainment of minimum strength required for frost resistance, improved durability (for example, reduced water absorption and improved impermeability of the concrete).

Chloride-free accelerator in powder form for the production of concrete precast elements with very high early strength; suitable for any concrete and reinforced concrete acc. to EN 206-2; significant shortening of demoulding cycles; faster circulation of moulds; cold weather concreting. Accelerates the rate of hydration of cement; significantly increases early strength while maintaining final strength.

Extension of workability time, e.g. for bridging of extended transportation or installation times, avoidance of construction joints, reduction of temperature peaks, specially in massive concrete components. Retarder for all concrete applications including concrete for road decks and bridges.

Self-compacting concrete (SCC), concrete in slump class F2-F6, concrete precast, ready-mix concrete, concrete with very low w/c values and high high slump, prestressed concrete. Special superplasticizers for high exposed concrete quality, with good initial plasticizing action, slump retention and high early strength development at the same time.

High-performance superplasticizer of the latest generation for concrete precast elements with highest early-strength made from medium slump, high slump or self-compacting concrete (SCC). Very strong increase of workability and/or reduction of w/c-ratio; very high early-strength development; moderate slump retention.

High-performance superplasticizer of the latest generation for medium slump, high slump and selfcompacting concrete (SCC) with high early strength and good slump retention, low concrete viscosity, low stickiness. Very strong increase of workability and/or reduction of w/c-ratio; high early-strength development; good slump retention; easy to trowel-smooth concrete surface.
