  • The variation in impact resistance of steel fiber-reinforced concrete and plain concrete as determined from a drop weight test is reported. The observed coefficients of variation are about 57 and 46% for first-crack resistance and the ultimate resistance in the case of fiber concrete and the corresponding values for plain concrete are 54 and 51%, respectively. The goodness-of-fit test indicated poor fitness of the impact-resistance test results produced in this study to normal distribution at 95% level of confidence for both fiber-reinforced and plain concrete. However, the percentage increase in number of blows from first crack to failure for bothmore » fiber-reinforced concrete and as well as plain concrete fit to normal distribution as indicated by the goodness-of-fit test. The coefficient of variation in percentage increase in the number of blows beyond first crack for fiber-reinforced concrete and plain concrete is 51.9 and 43.1%, respectively. Minimum number of tests required to reliably measure the properties of the material can be suggested based on the observed levels of variation.« less
  • Permeability and impact resistance of polypropylene-fiber-reinforced concrete mixtures containing silica fume with variable design proportions were studied. Two fiber lengths were considered, 12.5 and 19 mm, and four fiber volume fractions, 0, 0.1%, 0.3%, and 0.5%. Silica fume was used as a replacement by weight of cement. Two silica fume contents were used, 5% and 10%. Results showed that the incorporation of polypropylene fibers increased the permeability of conventional concrete. The addition of silica fume improved fiber dispersion in the cementitious matrix, causing a significant reduction in the permeability of the polypropylene fiber reinforced concrete. Moreover, the addition of silicamore » fume was noted to significantly enhance the polypropylene fiber effectiveness in improving the impact resistance of concrete.« less
  • The long-term corrosion process of reinforced concrete beams is studied in this paper. The reinforced concrete elements were stored in a chloride environment for 17years under service loading in order to be representative of real structural conditions. At different stages, cracking maps were drawn, total chloride contents were measured and mechanical tests were performed. Results show that the bending cracks and their width do not influence significantly the service life of the structure. The chloride threshold at the reinforcement depth, used by standards as a single parameter to predict the end of the initiation period, is a necessary but notmore » a sufficient parameter to define service life. The steel-concrete interface condition is also a determinant parameter. The bleeding of concrete is an important cause of interface de-bonding which leads to an early corrosion propagation of the reinforcements. The structural performance under service load (i.e.: stiffness in flexure) is mostly affected by the corrosion of the tension reinforcement (steel cross-section and the steel-concrete bond reduction). Limit-state service life design based on structural performance reduction in terms of serviceability shows that the propagation period of the corrosion process is an important part of the reinforced concrete service life.« less
  • The concrete decontamination and decommissioning (D&D) process using microwave technology is investigated theoretically in this paper. A one-dimensional uniform plane wave is assumed for the microwave Propagation and the Microwave field and the Power dissipation within the concrete. Also, by considering the effects of the microwave frequencies, a one-dimensional model of unsteady heat and mass transport in the concrete is developed to evaluate variations of the temperature and pressure distributions with the heating time. The effects of the microwave frequency (f), microwave power intensity, (Q{sub 0,avg}), the thermal boundary conditions on the front wall, and the concrete porosity ({phi}) onmore » the microwave power dissipation (Q{sub d,avg}), temperature (T), pressure (P), and evaporation rate ({Delta}m) distributions are all investigated in the present model. Finally, the effects of the presence of a steel reinforcement and its location on the microwave power dissipation, and the temperature and inner steam pressure distributions are discussed accordingly. 16 refs., 5 figs., 2 tabs.« less
  • The paper presents experimental data generated for calibrating finite element models to predict the performance of reinforced concrete panels with a wide range of construction details under blast loading. The specimens were 1.2 m square panels constructed using Normal Weight Concrete (NWC) or Fiber Reinforced Concrete (FRC). FRC consisted of macro-synthetic fibers dispersed in NWC. Five types of panels were tested: NWC panels with steel bars; FRC panels without additional reinforcement; FRC panels with steel bars; NWC panels with glass fiber reinforced polymer (GFRP) bars; and NWC panels reinforced with steel bars and external GFRP laminates on both faces. Eachmore » panel type was constructed with three thicknesses: 152 mm, 254 mm, and 356 mm. FRC panels with steel bars had the best performance for new construction. NWC panels reinforced with steel bars and external GFRP laminates on both faces had the best performance for strengthening or rehabilitation of existing structures. The performance of NWC panels with GFRP bars was strongly influenced by the bar spacing. The behavior of the panels is classified in terms of damage using immediate occupancy, life safety, and near collapse performance levels. Preliminary dynamic simulations are compared to the experimental results.« less
