AbstractAbout AuthorsReferences
Disperse reinforcement of the concrete with fibrillated synthetic fiber makes it possible to compensate of disadvantages of the concrete: formation of shrinkage cracks, low-tensile strength, and destruction brittleness. As a result of comparative tests, it is established that the introduction of micro-fiber Fibrofor High Grade in the concrete insignificantly improves the compressive strength limit comparing with the control composition but significantly improves the strength limit at bending stress (by 20%). The most acceptable expenditure of the micro-fiber for the concrete studied is 0.9 kg/m3.
