SAMPLES

• Yes, we do offer samples for B2B respective B2C clients. Volume at least 500kg. We ship in BigBags.

SHIPPING COSTS

• Shipping costs can vary - depending on the destination country.
• With your order, we will check the shipping costs and send you an new offer including shipping costs.

• Pick up in Kassel, Germany is possible

WHAT KIND OF MIXER DO I NEED?

• Please use a compulsory mixer to mix the pre-mix. The mixing energy and intensity is very important for the workability and the mechanical properties of the material. 
• Please do not use a drill machine with curl. The mixing energy and the equal distribution of the pre-mix in the mixing drum is not given.
• The type of mixer, mixing regime and processing do have an influence on the mechanical properties.

Mixing volume?

• Please use at least 2/3 of the mixer volume to work with our material.
• 1kg units shall not be mixed (not even in a kitchen-aid mixer)

How long do I have to mix?

• Please follow the instructions printed on the bags and see the video above.
• The mixing time depends on the mixing energy. It will take a while until the material becomes fluid in the mixer.

- start mixing with the amount you need

- after one minute add 90% of the water that is required for the volume

- after 2 minutes add last 10% of the water

- mix till the material changes from earth-moist to fluid

- mix further 2 minutes

Can I add more water?

• The mix is already optimized. Don't add water.
• If the workability is not high enough, you can add water, but due to this the mechanical properties will change and micro cracks can appear.
• Instead of adding water, you can add superplastizicer.
• IF THE WORKABILITY IS NOT OK - PLEASE CONTACT OUR SERVICE TEAM.

Temperature?

• If the temperature is to high, the material hardens very fast and the workability gets worse. To prevent this, please use ice to cool down water and use the cold water for the mixing process.

Can I add color pigments?

• Yes - you can. By adding pigments you will change workability as well as mechanical properties. The pigments can have an significant influence.
• When using pigments, please choose pigments that can be used with concrete. Only alkali resistant pigments will have a color stability.

Can I add fibers?

• Yes - you can. By adding fibres you will change the workability.
• Add the fibres when the material is already fluid. 
• By addig to much fibres, the uhpc can get clay like material behaviours respective a clay like workability.
• Fibers are improving performance and reduce shrinkage cracks as well as increasing the flexural strength.
• You can add Glassfibers, PP fibers, PVA fibers, Steel fibers, ...

Can I use and add local available sands?

• Mixing other additional gravels is possible and based on individual responsibility. 
• By adding other raw-materials, the mechanical properties, workability and other physical parameters will change.
• By adding more water due to adding other raw-materials, the mechanical properties can change.
• Clients can self dependent act and produce modified concretes based on myUHPC or Grayshape.

Is there an additional SP needed?

• No.
• In case you need the material more fluid, please provide us the information of your SP. We will give you a recommendation. DO NOT JUST ADD WATER, PLEASE.

What is the mix design to be used with your binder? I understand you are selling a ready to mix product but is it not too expensive to ship sand and aggregate?

• myUHPC and Grayshape are Ready-Mix materials. Everything is included - you just have to add water.
• The materials are nano optimized and so each fine, particle and aggregate is concerted to each other. That allows to produce a high quality material. You don't have to have an internal quality control.
• Mixing with other additional gravels is possible but based on individual responsibility.
• Shipping of larger concrete volumes is not expensive. We can estimate the shipping costs - please contact us. 
• We do offer special services for individual solutions. Those services will be charged with a development fee.

How much water do I have to add to the premix?

• Please follow the instructions on the label fixed at the package.

 How much water do I have to add to the grayshape premix?

•  per 1,0 kg Grayshape pre-mix ‚grey‘, please add 0,1 kg Water

Can I add more water?

• The mix is alread optimized. Don't add water.
• If the workability is not high enough, you can add water. By adding water, the mechanical properties will change and micro cracks can appear.
• Instead of adding water, you can add superplastizicer.
• IF THE WORKABILITY IS NOT OK - PLEASE CONTACT OUR SERVICE TEAM.
