The paper shows the effectiveness of the use of a polyfunctional complex modifier for a gypsum-cement-pozzolanic binder (GCPB), which allows reducing the water requirement of the mixture by 35%, increasing the flexural strength of gypsum-cement-pozzolanic composites (GPPC) by 28%, and 25% for compression. The results of experimental studies of the effect of polypropylene fibers on the basic physicomechanical properties of a central processing center are presented. The performed studies have shown high efficiency of polypropylene fibers of the type VSM-II-6 for dispersed reinforcement of the central industrial park. The maximum increases in the values of the flexural strength (by 41.2%) and compression (by 20%) are achieved with their volume content in the amount of 1%. It should be noted that the introduction of the studied fibers with a length of more than 6 mm did not lead to the expected result, which is due to the formation of a heterogeneous structure of the GPPC
