Corrosion inhibiting admixtures are unique among other methods to protect reinforced concrete from corrosion damage. In this study, the effect of furfural on fresh and hardened properties mixes 35 45 MPa compressive strengths as well inhibition was evaluated. Furfural added at different dosages (1, 2 3% by weight cement) with without superplasticizer (HRWR). Different electrochemical measuremen...

Analyze the major tendency of degradation of concrete bridges through the study of the main causes of their degradation firstly; then analyze the process fold line of their degradation via the aspect of reliability; thirdly, study the law and the characteristics of the degradation of bridges from structural elements; eventually got the entire trend of the degradation of concrete bridges.

Cracks in concrete generally interconnect flow paths and increase concrete permeability. The increase in concrete permeability due to the progression of cracks allows more water or aggressive chemical ions to penetrate into the concrete, facilitating deterioration. The present work studies the relationship between crack characteristics and concrete permeability. In this study, feedback controll...

To increase the applications of Natural Rubber Latex Modified Fiber Reinforced HighPerformance-Concrete (NRLMFRHPC) in India, greater understanding of NRLMFRHPC produced with locally available materials such as cement , Fine aggregates , coarse aggregates, Metakaolin and Crimped Steel fibers is essential. In the present investigation, NRLMFRHPC has been produced with locally available aggregate...

Experience in the design of steel and concrete floor systems to control vibrations suggests that a floor system’s vibration characteristics are often fundamental to its acceptable performance. In such cases, serviceability drives the design instead of strength. This is particularly true for laboratory floors that support sensitive equipment and floor girders that fall within certain spans. This...

Abstract Inter-vehicle communication system using 720 MHz band to prevent car crashes at an intersection has been proposed in Japan recently. In this paper, the propagation characteristics at an intersection surrounded by concrete block walls in residential area were analyzed by using the FDTD method for the first time. We investigated the influence of wall thickness and source locations on the...

The characteristics of a PZT ceramic element embedded in concrete are studied in this article. Based on the theory that the material coefficients of ceramic change their values under different stress levels, a method of measuring concrete stress by detecting the characteristics of the embedded ceramic element is proposed. The experiment uses a network analyzer to monitor some physical parameter...
