废石膏粉煤灰石灰结合料的研究

研制一种主要以磷石膏粉煤灰和石灰组成的无机结合料,并对其材料组成进行了优化研究。其最佳配比为:粉煤灰∶磷石膏=1∶1;石灰类稳定剂掺量约为6%~8%,其强度高于石灰粉煤灰结合料。结合料压实度为93%~96%,可作低等级路面基层材料和路面底基层材料,当压实度在93%时,可作路基的填筑材料和底基层使用。也可用其稳定砂砾、碎石作高等级路面基层和底基层材料。用SEM对其微结构进行了观察,阐述了其强度形成机理。脱硫石膏也可以代替磷石膏作为一种强度激发剂用于制备这种结合料。

THE BACK-TO-THE-CITY MOVEMENT REVISITED

ABSTRACT: Mounting evidence of residential neighborhood revitalization in the early to mid-1970s and impressions that such activity was based on a back-to-the-city movement promoted optimism about the future of cities However, studies conducted during the late 1970s to evaluate this phenomenon questioned its existence. This not only had a chilling effect on the belief in the renaissance of cities, but also undermined concerns about the major liability that had become associated with the back-to-the-city movement: residential displacement An evaluation of these studies indicates that their findings and conclusions about the back-to-the-city movement were not justified The results of this study show that many home buyers are moving into cities from non-city areas. It also shows that this migration causes considerable displacement problems. This article is organized into two sections. The first presents a background for the back-to-the-city movement including an evaluation of the previous studies. The second describes a study of two neighborhoods undergoing revitalization in the city of Hartford Connecticut, which attempts to address the questions raised about the previous studies and presents its findings.

PLANNING,ANXIETY AND IMPERIAL IDENTITY IN EARLY TWENTIETH CENTURY SYDNEY

Imperial identity in Australia in the first half of this century was a complex affair, with ties to Britain intersecting nationalist sentiments. It was also strongly marked by class concerns. This paper examines certain imperial sentiments as expressed through the ideals of the early proponents of town planning in Sydney. Planning was seen as an adjunct to the strengthening of Empire through its concern with producing fitter and healthier urban inhabitants. How planning advocates proposed to go about this, and to what specific ends, reveals much about their ideals, their anxieties and their embrace of planning as an ideological reflex.     

Impacts of airtightening retrofits on ventilation rates and energy consumption in a manufactured home

A retrofit study was conducted in an unoccupied manufactured house to investigate the impacts of airtightening on ventilation rates and energy consumption. This paper describes the retrofits and the results of the pre- and post-retrofit assessment of building airtightness, ventilation, and energy use. Building envelope and air distribution systems airtightness were measured using fan pressurization. Air change rates were measured continuously using the tracer gas decay technique. Energy consumption associated with heating and cooling was monitored through measurement of gas consumption by the forced-air furnace for heating and electricity use by the air-conditioning system for cooling. The results of the study show that the retrofits reduced building envelope leakage by about 18% and duct leakage by about 80%. The reduction in the house infiltration rates depended on weather conditions and the manner in which the heating and cooling system was controlled, but in general these rates were reduced by about one third. The energy consumption of the house for heating and cooling was reduced by only about 10%, which is relatively small but not totally unexpected given that infiltration only accounts for a portion of the heating and cooling load.     

Real climate experimental study of two double window systems with preheating of ventilation air

This paper aims to characterize the thermal performance of a window system that consists in doubling an existing window, converting it into a ventilated double window. The air coming from the outside circulates upwards through the channel between windows and enters the building through a vent on the top of the window's case. A series of experimental measurements was conducted in a test cell exposed to real outdoor weather conditions located in a mountain region at Centre of Portugal, during heating season in order to determine how this window system can act as a heat exchanger. It was found that such window system act as an efficient heat exchanger using transmission heat losses and solar radiation to preheat ventilation air, thus reducing the building's operational energy costs. An average of about 19 m³/h of air flow rate was found with an air temperature increment within the air gap of about 6 °C, during night-time, for an indoor/outdoor temperature difference of about 16 °C. Air temperature increment reached up to 12 °C using a plastic shutter. With solar radiation, the average of that increment was about 10 °C. This is a simple and cheap building technology which can be implemented both in new and existing buildings.     

空中街道与史密森夫妇建筑实践

“空中街道”是史密森夫妇建筑设计生涯所关注的重要议题。建筑师对于“认同感”与”归属感”的思考．以及对当时欧洲被CIAM理性主义所主导的住宅建设的批判激发了这一概念的产生。”空中街道”在金巷住宅竞赛中提出．并多次出现在日后他们的建筑方案设计中．最后在罗宾花园住宅项目得以实现。脱离地面的“空中街道”缺乏保持生活活力的多样性．史密森夫妇设想的街道生活并没有出现。但他们对“空中街道”的探索．为后人提供了一个思考“城市，社区、街道与居住”的新角度。
