| Title of the article | Improvement of technology and quality control for the construction of monolithic fiber-reinforced concrete structures |
| Abstract. | Problem Statement. Reducing the labor intensity and time required to construct monolithic structures while simultaneously ensuring high quality of finished construction products is the most important area for improving this technology. Traditional rebar reinforcement is a resource-intensive process, and the use of fiber-reinforced concrete requires solving problems related to ensuring the mix uniformity and controlling its properties. The aim of the work is to improve organizational and technological solutions for monolithic fiber-reinforced concrete structures by solving the problems of an integrated approach to material modification and technology control. Results. A three-stage quality control system has been developed and tested, comprising input, operational, and acceptance control. The system’s specificity lies in the regulation of operations for dosing steel fiber and carbon nanotube suspension, two-stage mixing, and monitoring the kinetics of hardening. It has been established that the combined use of steel fiber and nanotubes in the concrete mix composition provides a synergistic effect. It has been experimentally confirmed that the proposed solution ensures a 45% reduction in labor costs by eliminating rebar cage installation operations and reduces the construction cycle duration by twenty-five percent due to the intensification of concrete hardening. Conclusions. The significance of the obtained results for the construction industry lies in the development of an organizational and technological solution ready for practical implementation. Its implementation makes it possible to significantly increase the efficiency of monolithic construction by reducing labor intensity and shortening project timelines while guaranteeing the required physical mechanical characteristics of the fiber-reinforced concrete structures. |
