Smolyaninov M. The increase of reinforced concrete elements strength and crack resistance of acrylic composition solution under short-term static and frequent loading

Object is strengthening of the compressed 30and bent reinforced-concrete elements of building constructions acryls composition solution Purpose is determination of durability, deformation, crack resistance and endurance of the concrete and reinforced-concrete elements increased by acryls compositions, at the action of brief static and repeatedly the repeated ladenings with high and low frequencies. Methods are analytical, experimental, comparative analysis. Novelty – data on of bearing strength and endurance of reinforced-concrete elements of the building constructions increased by acryls compositions is first got, at the action of static and repeatedly the repeated ladenings with frequencies 7; 4,2 and 0,1 Hertzs, the base number of cycles is first got repeatedly the repeated ladening for the reinforced-concrete elements increased by acryls composition solution, with frequency 0,1 Hertzs. Results - calculations descriptions of the investigational reinforced-concrete elements increased by acryls compositions are got, providing their joint work at the action of brief static, so repeatedly the repeated ladenings; the results of developments allow to make a calculation and constructing of concrete and reinforced-concrete elements of increased by acryls composition solution at the action of static and repeatedly the repeated loadings; the sphere of the use is strengthening, renewal, repair, reconstruction.
