FUNCTIONAL ACTIVITY IN THE COMPOSITION OF AN ADDITIVE TO BIOCONCRETE

The work investigated bioadditives to concrete based on immobilized bacteria Bacillus licheniformis. Drying options and the state of microorganisms during immobilization affect their functional activity in the composition of the biological product. The addition of biological products with freeze-dried spores and cells immobilized on diatomite into the cement mixture significantly improves the strength characteristics of the cement stone.
