Prediction of Compressive Strength of Concrete with Decision Trees
Abstract: In the past few researchers predicted the compressive strength of concrete from its ingredients employing data driven technique like artificial neural network (ANN) and Decision Tree (DT). For Indian concrete records, only one study was available which had employed ANN for prediction. Evaluation of different performance metrics indicated that there was scope of improvement in the prediction performance. In this paper experimental data from the literature was utilized for development …

Review Study on re-strengthening of reinforced concrete circular column using steel strips
Abstract: This technique fixes thin steel plates i.e. steel encasement or tie plates i.e. steel cage around the column with steel angles at each corner, clamped to the concrete and welded together. Adequate tightening of the jackets can be ensured by means of heat tensioning. The use of steel jackets can enhance the shear strength of columns considerably. However, due to their low flexural stiffness they typically have poor confinement efficiency …

An Investigation on Aggregate Distribution in Concrete
Abstract: Falling behavior is generally studied by mathematicians. The first study is conducted by Comte de Buffon with name “Falling needles experiment” and is widely known. Buffon researched the falling needle behavior finding the fall of needles in relation with Pi. However, although aggregates are fallen to the mould in cement paste, falling behaviour of concrete is rarely studied considering the statistical parameters of the fall.Accordingly, an experimental study is conducted …

Study on Properties of Concrete Cured With Poly Ethylene Glycol-600
Abstract: After water, concrete is the most using material globally. Without concrete, the world is unimaginable. The foundation of civilization is concrete. Coarse aggregate, cement ,fine aggregate and water are the main ingredients in concrete, which requires curing to attain its strength. Concrete must therefore cure for 28 days in order to complete the necessary hydration, desired strength. For the traditional curing processes, a lot of water is needed. This becomes …

Experimental Investigation of Concrete Properties for Strength and Durability with Partial Replacement of Mixture of Nano-Silica
Abstract: This study explores the effects of partial cement replacement with nano-silica on theproperties of concrete, focusing on both strength and durability aspects. Compressive strengthtests were conducted at two key ages, 7 days and 28 days, to evaluate the concrete's performanceunder various conditions. The nano-silica was introduced into the concrete mix at three differentpercentages: 0.3%, 0.6%, and 1% by weight of the cement content. Our experimental findingsindicated a remarkable enhancement in …

Application of High-Speed Videography in Assessing the Performance of Blasts
Abstract: Abstract Blasting can be considered as the most crucial process in an opencast mine. It is therefore important for mining engineers to understand the effect of geological discontinuities and blast design parameters on the results of blasting. Bench height and burden are very important parameters affecting stiffness of bench. Joints alter the results of blasting, by making explosive energy utilization ineffective. Modern tools like high-speed videography reveal many aspects of …
