The effect of mining waste on the durability indicators of cement-based composites

The need for infrastructure development is of major importance and the projected global infrastructure investment between 2013-2030 is estimated in the excess of £30 trillion to support the rapid growth of societies and economies worldwide (1). This trend puts civil infrastructure industry under immense stress to plan properly, construct fast...

Material flows of the German building sector

According to estimates of the German Federal Ministry for the Environment, the German building stock contains around 10.5 billion tonnes of mineral building materials, around 220 million tonnes of timber products and around 100 million tonnes of metals. Due to continuous building activities, especially renovation and retrofit measures, it is...

Deconstruction, preparation for reuse and reuse of salvaged materials on a pilot construction site in Brussels

Since a few years, the construction sector is focusing on minimizing resources exploitation and waste arising on construction sites. The European Commission has highlighted prevention and reuse as key actions for waste management. The Brussels Capital-Region is a densely built region, generating more than 600 000 tons of C&D waste each year....

Exploring Reciprocal Relationships of Land-Uses in a Historical Mixed-Use Quarter of Istanbul: Measuring mixed-use patterns of Cihangir

In this paper we explore the land-use patterns of a historical mixed-use quarter of Istanbul by focusing on the reciprocal relationships of housing and commercial uses. We are concerned with the distribution of land-use patterns based on spatial adjacency and land-use patterns within the buildings. We measure reciprocal relationships of housing...

Introducing an approach to access environmental pressures from integrated remediation and landfill mining

The aim of the paper is to introduce an approach for evaluating integrated remediation and landfill mining scenarios. Since completed projects with similar scope and goals mostly have been pilot studies or projects with little emphasis on resource extraction, there is very little real case data to access. Thus, scenarios for three different...

Multi-objective design exploration using efficient global optimization

Multi-Objective Design Exploration (MODE) and its application are presented. MODE reveals the structure of the design space from the trade-off information and visualizes it as a panorama for Decision Maker. As an optimizer for MODE, Efficient Global Optimization (EGO) based on the Kriging model has been extended to Multi-EGO to solve multi...

Design Exploration of Shielding Effect for Aircraft Engine Noise

The multi-objective design exploration of the two-dimensional shielding effect for engine noise using V-tale wing has been performed. Two objective functions are considered as the minimization of the sound pressure level at the side and bottom locations relative to the fuselage, which values are evaluated by using the linearized Euler equation....

Design exploration of high-lift airfoil using Kriging model and data mining technique

A multi-objective design exploration for a three-element airfoil consisted of a slat, a main wing, and a flap was carried out. The lift curve improvement is important to design high-lift system, thus design has to be performed with considered multi-angle. The objective functions considered here are to maximize the lift coefficient at landing and...
