Chloride Ingress Resistant Concrete: High Performance Concrete Containing Supplementary Composites
1 Associate Professor of Structural Engineering College of Engineering, King Saud University Email: [email protected] Abstract – In Reinforced concrete structures chloride ion penetration is considered to be a major cause of corrosion of reinforcing bars. Conventional concretes fail to prevent the intrusion of moisture and aggressive ions adequately. The use supplementary cementing composite ma...
متن کاملModeling Chloride Penetration in Saturated Concrete
A mathematical model is established for chloride penetration in saturated concrete. The model takes into account various influential parameters such as water-to-cement ratio, curing time, types of cement, and aggregate content. Two material models are developed for binding capacity and chloride diffusivity, which have a dominant effect on the chloride diffusion process. The chloride binding cap...
متن کاملEffect of Transverse Crack on Chloride Penetration into Concrete Subjected to Dryingâ•fiWetting Cycles
In this paper, several transversely cracked RC beams, self-anchored in a three-point bending mode, were prepared and subjected to NaCl solution drying–wetting cycles. Based on two experimental results obtained after 15 and 30 cycles, respectively, the profiles of free chloride concentration at different sections of sound and cracked concretes were presented and analyzed. The depth of surface co...
متن کاملResearch on Chloride Penetration Resistance of Phosphoaluminate Cement Concrete
The chloride penetration resistance of phosphoaluminate cement (PAC) concrete was investigated in this study. The effects of mixture proportioning parameters, including cement content, water–cement ratio (w/c), and superplasticizer content on chloride ion penetration resistance of PAC concrete were investigated by the rapid chloride migration test (RCM). The result shows that the increase of ce...
متن کاملCenter for By-Products Utilization RESISTANCE OF HIGH-QUALITY CONCRETE (HQC) TO CHLORIDE ION PENETRATION
A research program was carried out to evaluate the chloride ion permeability of both air and non-air entrained concretes made with mineral admixtures as partial replacements of cement. Two series of investigations (Series 1 and Series 2) were carried out. The mixtures were proportioned to have 28-day strengths of 35 MPa for Series 1 and 69 MPa for Series 2. Chloride ion permeability was determi...
