The following research projects will receive funding from the ACI Foundation:
Standard Critical Chloride Threshold Test Variability due to Material Sources: principal investigator Ceki Halmen, University of Missouri - Kansas City. Endorsed by ACI Technical Committee: 222 Corrosion of Metals in Concrete.
The large variability of published CT data and lack of a standard CT test method creates significant difficulties for the concrete industry. Researchers cannot compare CT values obtained from their research to a standard value. Practitioners evaluating condition of reinforced concrete structures for maintenance and rehabilitation cannot make a reliable assessment based on measured chloride contents. Designers cannot estimate the service life of their design without a reliable estimate of critical chloride threshold value. Development of a standard critical chloride threshold test with a complete data set regarding its variability will alleviate these issues.
Abstract
In this paper, the mechanical properties of magnesium phosphate cement (MPC) was enhanced by adding fiber and nano-Al O . The effects of fiber and nano-Al O on the workability, compressive strength and flexural toughness of MPC were studied. The variables of the experimental investigation included the types of fiber, fiber volume fraction, nano-Al2O3 substitution rate and curing time. The experimental results showed that the workability and the mechanical properties of the MPC could be improved by adding nano-Al O . The workability decreased gradually with increasing fiber content, while the compressive and tensile strength gradually increased. Among different types of fiber, the micro-steel fiber (MSF) had the most significant effect on the improvement of flexural toughness. Based on the analysis of experimental data, empirical formulae for predicting the compressive strength and splitting tensile strength of fiber and nano-Al O reinforced MPC composite (FNRMC) were prop
