Understanding knowledge risks in Construction Organizations: Focus towards conceptual framework
Abstract: Managing knowledge by only considering it as a strategic asset is insufficient for understanding it and making well-informed decisions. And yet, knowledge risks and their management are still very little known. To fill the gap, this paper analyses the concept of knowledge as a risk or liability and creates a conceptual framework for understanding knowledge risks inside construction organizations. Balancing the depth and coverage of knowledge risks, theoretical results, and …

Fracture and Failure of Recycled Aggregate Concrete (RAC) – A Review
Abstract: In the world, many countries put into effect the renewal plans and/or the laws and/or the regulations for recent engineering structures which have reached their lifetime, are risk prone and have been built lacking quality engineering, or without considering urban planning. Hence, many structures are demolished and this situation increases the amount of construction and demolition waste (C & DW). Also, resource consumptions are rapidly increased due to excessive constructional …

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 …
