Would there be a differance in the strength of a product if gypsum plaster was mixed by hand in product (A) or mixed with a mechanical mixer (B) If so why?

Hand mixing will not give the uniform consistency that mechanical mixing will. If the wet product is not consistent, the dry finish will not be either.

If hand mixing is the only option................smaller batches= better mix.

Hi thanks for the input we use both formats with no problems but I was told that mixing with mechinical mixer would transfer the energy put in , would be absobed by the plaster and therefore would be stronger can this be true and if so how would this ocure If this is so then I we could use less plaster to water mix to get the same results as a mix with more plaster to water mixed by hand? Regards Andre

We use +-- 40,000 kg per month

Did you really believe this?

I'm guessing that someone is trying to sell you something.

The entire concept is rubbish.

Machine mixing very likely produces a stronger product. Like kramarat says.

The energy (heat) imparted into the mixture by the paddles of the machine would reduce the apparent viscosity of the mixture thereby enhancing the mixing of the materials (breaking up smaller clumps, etc.) and producing a stronger product.

There is no other "energy" infused into the product to make it stronger.
