The paper presents practical utilisation in the construction of a parking lot of compositions based on waste (phosphogypsum) from the wet process of orthophosphoric acid manufacture. The results of strength tests performed after half a year and after one and a half year of parking lot operation confirmed the feasibility, established earlier in laboratory tests, of utilising phosphogypsum mixes with fly ash and stabilising binder.

Potassium multiphosphates for food processing

100%

Cichy B., Folek S., Makała H.

The paper discusses the results of research on the preparation of food grade potassium di- and triphosphates and the application thereof as multiphosphate ingredients of functional additives for meat processing. The research on the process of potassium multiphosphate manufacture was performed with the use of equipment corresponding to that used on an industrial scale, facilitating thereby the transfer of the process conditions to a commercial level. The aim of the work was to obtain potassium di- and triphosphate products readily soluble in water and NaCl solutions, determination of optimum parameters of the manufacturing processes, and an application of the products obtained along with sodium multiphosphates in functional phosphate additives for selected meat products. The research presented here is part of an on-going project.
