OPTIMAL DESIGN OF THE COMPOSITION OF A COMPOSITE BINDING AGENT OF A DRY CONSTRUCTION MIXTURE AND A MORTAR BASED ON IT BY THE METHOD OF MATHEMATICAL PLANNING OF EXPERIMENTS

The article presents the results of experimental studies on optimization of the composition of the composite binder of the dry building mixture (DBM) and the solution based on it for masonry and plastering works using the method of mathematical planning of experiments.It was established that the optimal values of the consumption of structure-forming additives: zeolite-containing rock of the Beltau deposit and the dosage of the Impact Factor: ISRA (India) = 6.317ISI (Dubai, UAE) = 1.582GIF (Australia) = 0.564 JIF = 1.500SIS (USA) = 0.912 (Russia) = 0.191 ESJI (KZ) = 8.100 SJIF (Morocco) = 7.184 ICV (Poland) = 6.630PIF (India) = 1.940IBI (India) = 4.260 OAJI (USA) = 0.350 Philadelphia, USA 135 chemical additive CWR in the composition of the composite binder DBM are 28% and 0.9% of the mass of the mixed binder, respectively.
