STRENGTHENING OF CONCRETE AS A RESULT OF FILLING OF THE PORES AND CAVITIES

摘要

A technology of strengthening of concrete based on the procedure of filling of the pores and cavities with liquid materials capable of polymerization or crystallization after a certain period of time is theoretically substantiated. The conditions of growth of cracks formed on the contour of a circular hole under the conditions of compression are established. We also study the influence of stiffness of the material of the filler on the efficiency of strengthening of the body containing a hole and cracks.
