[Composite porosity depending on the powder-fluid quotient, the mixing process and the methods of application]

Porosity (number of pores, pore size distribution, relative area of pores) of powder/liquid composite depended on processing conditions (powder/liquid ratio, manual or mechanical mixing, method of application). The minimum number of pores and the least relative area of all pores in a cross-section of the sample was found in the mechanically mixed composite. Injection-capsule composites are recommended. Application in small portions should be avoided. The higher the powder/liquid ratio the higher the number of pores and relative area of pores. The ratio of components and the method of application have a different effect on the pore size distribution.
