Effect of low-modulus polypropylene fiber on physical and mechanical properties of self-compacting concrete

The article presents the results of laboratory experiments investigating the necessity and expediency of disperse reinforcement of self-compacting concrete (SCC) to increase its physical and technical parameters and the study of deformative properties of SCC with the use of fibers. For collaboration...
