  • Grain-Size Distribution of Mixed Aggregates

    When various aggregates are to be combined in order to obtain a mix having a desired grain-size distribution, current methods are based on a trial-and-error approach. It is shown in this paper that the process of combining various soils or aggregates may be a simple, rapid, and efficient procedure that eliminates the need for trial and error. The paper presents the formulation of the combination ...

  • Prediction markets: an information aggregation perspective to the forecasting problem

    Lately, traditional forecasting methods have been depicted as inferior to newer ones which are attempting to simulate the human decision making process. However, this goal might even be impossible to achieve. This paper introduces an inverse approach to the forecasting problem. The typical process of attempting to subtractively model the expert's knowledge and cognitive function and then perform ...

  • Stabilization and utilization of hospital waste as road and asphalt aggregate

    This article reports the operational results of the effective utilization of hospital waste molten slag produced using a high-temperature melting system, and being operated at a hospital in Selangor, Malaysia. The hospital waste is incinerated and subsequently melted at 1200°C. Scanning election microscope (SEM)/EDX results showed that the slag produced after melting contained amounts of SiO2, ...

  • Material flows analysis of construction aggregates in Taiwan

    Recent decades of economic and industrial development have accelerated the demand for and use of construction aggregates in Taiwan. Material Flows Analysis (MFA), the most common analysis tool of the scientific field of industrial ecology, was employed in this study. The study calculated, within a decade period, the deposits, domestic production, demand, import, export, per capita and per unit ...

  • Portable Crusher is popular in recycling aggregate concrete

    Portable Crusher is a new designed rock crushing & screening plant, which is flexible, convenient and strong in mobility, so it can save a large construction capital and relocation. Raw Materials can be broken at the locale without being transported again and also can be moved with the promotional exploitation of the raw material, which saves a ...


  • Real options econometrics for aggregate tanker investment decisions

    Understanding the limitations of the Discounted Cash flow Methodology (DCF) has resulted in increased usage of the real option analysis for ship investment decisions under uncertainty. In this paper, our contribution is two-fold: We propose an equilibrium model for explaining aggregate investment behaviour in the new building industry for tankers and provide a framework for testing the real ...

  • Construction Aggregate Mining: Sand and Gravel - Case Study

    In 1995, we helped a company locate sand and gravel volumes in San Marcos, Texas. This material can be mined and sold for construction purposes. Process The Sting R1 with 47 Dual-Mode Swift electrodes was spaced three meters apart. Two parallel lines were collected eight meters apart to identify conductive silt/clay/shale and resistive ...

  • Application of analytic hierarchy process to prioritise urban transport options – comparative analysis of group aggregation methods

    This paper presents a comparative analysis of different group aggregation methods adopted in analytic hierarchy process by testing them against social choice axioms with a case study of Delhi transport system. The group aggregation methods and their correctness were tested while prioritising the alternative options for energy efficient and less polluting transport system in Delhi. It was observed ...

  • Integrated life cycle management of aggregates quarrying, processing and recycling: definition of a common LCA methodology in the SARMa project

    Most of the environmental knowledge, presently used to understand or design sustainable industrial systems, is derived from an application of life cycle assessment (LCA). The mining/quarrying industry is probably one of the sectors where there has been relatively less use of LCA tools, or where LCA has received less consensus. A key issue is the integration between three interdependent life ...

  • Quantity of Fines Produced During Crushing, Handling, and Placement of Roadway Aggregates

    A three part test procedure was developed to determine the quantity of fines produced during crushing, handling, and placement of aggregates used as base course in roadway construction. The first test simulates crushing at the aggregate source. It involves processing an aggregate sample of specified gradation through a small laboratory jaw crusher. The second test simulates handling by agitating ...

  • Image analysis of sludge aggregates obtained at preliminary treatment of sewage

    The results of wastewater treatment by Al and Fe salts and by electrocoagulation with aluminum electrodes are discussed and interpreted. Those processes used alone or combined with biological treatment, were analyzed for 50 and 90% removal of phosphates. Scanning electron microscopy (SEM) of the resulting sludge from three coagulation processes defined the perimeter P and area ...

  • Aggregate stability and erosion response to antecedent water content of a loess soil

    Soil erosion processes are affected by the erodibility of the soil and by the erosivity of the rain. The effects of rain characteristics and invariant soil properties such as texture and organic matter content on soil erosion processes are well documented. The effect of antecedent soil water content ({theta}a) on aggregate breakdown, seal formation, and subsequent soil erosion is much more ...

  • JPE Investment provides evidence of a solution to UK aggregates shortages

    An upgrade to the processing capability at Elford quarry to include a modular washing plant from CDE Global has resulted in a significant increase in the value of the products being produced. The level of demand for the recycled sand and aggregate products suggests that C&D recycling plants offer a real solution to a diminishing supply of virgin material in the UK. JPE Aggregates has operated ...

  • Biomass aggregation influences NaN3 short-term effects on anammox bacteria activity

    The main bottleneck to maintain the long-term stability of the partial nitritation-anammox processes, especially those operated at low temperatures and nitrogen concentrations, is the undesirable development of nitrite oxidizing bacteria (NOB). When this occurs, the punctual addition of compounds with the capacity to specifically inhibit NOB without affecting the process efficiency might be of ...

  • How to aggregate sustainable development indicators: a proposed framework and its application

    Decision makers are constantly bombarded with indicators that can lead to indicator fatigue and information overload. Many decision makers call for a few aggregated indicators to simplify decision-making. This call has led to the development of several prominent aggregate indices such as the ecological footprint index and the living planet index. Despite this flurry of empirical index activity, ...
