THE USE OF AN ADDITIVE OF EXOMETABOLITE OF THE BACILLUS CEREUS MICROORGANISM, OBTAINED FROM WATERED-DOWN SOILS, AS A PLASTICIZER TO IMPROVE THE STRENGTH OF CEMENT SOLUTIONS

Abstract

Bacillus cereus. The effect of exometabolites of the microorganism of the strain Bacillus cereus, obtained from watered-down soils, on the strength of cement mortars is investigated. Quantitative indicators of increasing the compressive and bending strength of cement compositions with bioadditive are established. The optimal concentration of bioadditives was determined by the indicators of mobility of the cement mortar and the conditions of the process of biocementation. The effectiveness of the use of bioadditives in relation to cement systems is shown.
