Microwave measurement technology:Optimal mix ratio for correct dosing

Aerated concrete is popular for the production of wall and floor slabs, hollow and precision blocks and masonry. To guarantee the consistent quality of the end product, the components must be dosed precisely in compliance with the formula. The article introduces a new process for continuous determination of water content by measurement of the dry substance content.

Aerated concrete building material in various forms and densities is popular in the production of wall and floor slabs, hollow and precision blocks and masonry. It is essential for the high, consistent quality of the end product that the components, especially lime, cement and fine sand, are dosed precisely in accordance with the formula. Water is a decisive factor. The ProMtec Theisen company has developed a procedure that can help in continuous determination of the water content by measurement of the dry substance content. This occurs in-line during the process, which enables deviations...
