Pressure of Fiber Reinforced Concrete Mixtures on Vertical Formwork Panels

摘要

The article describes the developed methodology and installation for the experimental determination of concrete mixture pressure on the vertical formwork panels. This methodology is based on main positions of the strength of materials. The article presents the results of experiments on the pressure of deposited fiber reinforced concrete mixtures of different composition on the vertical formwork panels. The authors carry out the analysis of obtained results and draw generalized diagrams. The analytical formula for pressure of concrete mixtures is worked out and dimensionless factors in this formula are determined mathematically. The dimensionless factors are approximated by power functions with good convergence with actual values. The obtained results enable the reduction of the design values compared with those in the regulatory documentation.
