With our TEGNO® special cement you can easily manufacture ultra high performance concrete (UHPC) with compressive strengths beyond 150 Newtons per square millimetre. The basis for this revolutionary product is the NANODUR® technology from Dyckerhoff.
TEGNO® is used where particularly high demands on strength, surface hardness and dimensional stability exist, such as machine beds and machine frames, where it is even superior to steel.
Since TEGNO® is prepared with extremely little water, the addition of a suitable superplasticizer and the use of an effective mixer are mandatory. We recommend our superplasticizer FLUP® - PCE-375, specially tailored to TEGNO®, which you can order here in the shop. The superplasticizer should be added directly to the mixing water in order to encourage the plasticizing effect. Our FLUP® - PCE-375 now makes it possible to manufacture TEGNO® - Concrete (UHPC) in a cement mixer with mixing times under 10 minutes.
Our recommended standard recipe consists of 1 kg of TEGNO®, 410 g of washed sand (air dry, granulation size 0 to 2 mm) and 840 g of crushed basalt (air dry, granulation size 2 to 5 mm) plus 13 g superplasticizer FLUP®-PCE-375 and 160 g of water. A special concrete with an extremely high modulus of elasticity (E > 80 GPa) can be produced from TEGNO® in conjunction with our DURIGID aggregate. For this concrete the recipe consists of 1050 g of TEGNO®, 1193 g of DURIGID 1-3 mm, 430 g of DURIGID 3-6 mm plus 17 g superplasticizer FLUP®-PCE-375 and 149 g of water. Enter the length, width and height of your object in the CONCRETE CALCULATOR below and calculate your exact needs. Please note that when you use wet sand, it usually contains between 25 and 100% of the total allowable amount of water, and so reduce the amount of additional water accordingly. IMPORTANT NOTE: Do not use other additives such as accelerators or retarders.
