Abstract: Concrete crash barriers are structures provided to channel the road traffic and prevent catastrophic accidents resulting in loss of life. The failure of concrete crash barriers is often due to vehicular impact. Improved ...

Abstract: Geopolymer concrete is a sustainable material which can reuse industrial by-products and thereby minimize the emission of greenhouse gases during its production, unlike cement. Blended geopolymer concrete has been made ...

Abstract: This study uses fly-ash-based superplasticized geopolymer by adding a naphthalene-centered superplasticizer to the geopolymerized soil. Alkali-binder ratios and alkali-activator ratios are varied simultaneously with a ...

Abstract: This paper presents a study on the estimation of collapse load in single-cell box girder bridges under different modes of failure and the best suitable method to predict collapse load in each different case. Experimental ...

Abstract: Fencing posts are subjected to impact forces from animals like wild boars, wild cattle, and others that try to pass through them. Hence, improving the impact resistance of fencing posts is an issue of priority. Rubcrete ...

Abstract: Geopolymer concrete is a novel concrete that uses industrial wastes for its production process. The application of geopolymer concrete in construction is lower due to the dearth of sufficient information about the performance ...

Abstract: A curb is a barrier or a raised boundary provided to demarcate between the roadway and footpath or median. Curbs have a high probability of being subjected to impact loads due to collision from vehicles. The frequency of ...

Abstract: The nonlinear ultrasonic Lamb wave has attracted great attention recently due to its likelihood for microcrack detection in plate-like structures. Wave mixing technique has shown advantages over the conventional nonlinear ...
