General Purpose Cement With Increased Limestone Content In Australia, Iman Mohammadi, Warren J. South
General Purpose Cement With Increased Limestone Content In Australia, Iman Mohammadi, Warren J. South
Faculty of Engineering and Information Sciences - Papers: Part A
This paper discusses the effects of an increase in the maximum allowable limestone content of general purpose (GP) cement from 7.5 up to 12%. The substitution of a higher content of clinker with limestone will allow for a lower embodied energy and emissions associated with the manufacture of GP cement. Fresh and hardened properties of normal-grade concrete (N20 and N32) prepared with GP cement containing limestone contents in the range of 5 to 12% were investigated. The compliance of test results were checked and confirmed against the requirements of cement and concrete specifications. In addition, the test results were statistically …

Household relocation modelling is an integral part of the Government planning process as residential movements influence the demand for community facilities and services. This study will address the problem of modelling residential relocation choice by estimating a logit-link class model. The proposed model estimates the probability of an event which triggers household relocation. The attributes considered in this study are: requirement for bedrooms, employment status, income status, household characteristics, and tenure (i.e. duration living at the current location). Accurate prediction of household relocations for population units should rely on real world observations. In this study, a longitudinal survey data gathered …

Illicit heroin use is a worldwide problem, with significant health and social costs. Treatment is known to be effective in changing heroin use habits, but it often needs to be provided over a lifetime, with people cycling in and out of treatment. It is therefore important to capture a long-term perspective on heroin use careers. The aim of this project was to build a lifetime microsimulation model of heroin using careers. This paper describes the conceptual logic of the model, the input parameters and the verification and validation results. A microsimulation model was chosen as the most appropriate simulation platform …
A Bottom-Up Data Collection Methodology For Characterising The Residential Building Stock In Australia, Clayton Mcdowell, Georgios Kokogiannakis, Paul Cooper, Michael P. Tibbs

In Australia the majority of the current residential building stock has been constructed with little regard to energy consumption or thermal comfort. With only 1-2 % of Australia's building stock being replaced each year retrofitting solutions are necessary if residential energy consumption is to be reduced. Australia's records of the characteristics of its current building stock are minimal and outdated and thus these need to be renewed to enable the evaluation of retrofit upgrade strategies. Thus this paper presents a methodology and results of a bottom-up data collection tool that captured building and occupant characteristics from 200 elderly low income …
