Concrete elements - Import export

Air-detraining agent for low-pore, small and large-sized, constructional concrete precast elements. Reduces air-entrainment during concrete pouring and improves de-airiation of concrete during and after compaction; improves surface finish of fair-faced concrete.

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.

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.

Egglayer / block making machine system has a long tradition. The first automatic KNAUER egglayers / block making machines for the production of high-quality concrete products were developed in the 50s and 60s. The working principle remains the same. Referred to the investment / productivity ratio, the manufacturing of concrete elements like hollow blocks, landscape units, bricks, retaining wall units, etc. onto a concrete slab is to this day the most cost-effective and efficient method. KNAUER has continued to extend its egglayer / block making machines line and developed new concepts that are state-of-the-art. The KNAUER-system egglayers / block making machines are working today fully automatically, are controlled by PLC and are provides with the latest technology.

For KNAUER ENGINEERING-Vibrating Tables there are many fields of application in several industry branches. Examples: • Compaction of concrete elements • fast and economic filling and emptying of containers with bulk goods; • deairation of viscous liquids; • sorting and distributing of bundled tubes or similar elements. Besides some standard vibrating tables most vibrating tables are being designed and manufactured according to customer requirements. From small, simple vibrating tables up to very large tables with, e.g. hydraulic mould clamping, electronic amplitude adjustment and automatization.
