Recycling Ceramic Waste Powder And Its Usage As An Alternative Ingredient In Concrete, Dima Mamoun Kanaan

Theses

Green environment is a challenging concern to accomplish in today’s world. This could be accomplished through an effective and beneficial recycling system through reusing solid waste materials. The study and exploration of alternative ingredients for concrete-making industry started more than five decades ago. Concrete that contains solid waste is referred to as “Green” concrete. Ceramic tiles are widely used in most structures; its production creates waste powder. Using ceramic waste powder (CWP) as an ingredient to partially replace cement in concrete will have a positive and progressive environmental impact in addition will help reserve natural resources. In this study, CWP …

Beneficial Reuse Of Marine Sediment, Sinead Tangney

Theses

Dredging is essential for ports and harbours to maintain navigational access. In Ireland approximately 1.2 million m^ is dredged annually and the management of this dredged sediment is an ongoing issue. This thesis investigates the management options available for marine dredged sediment and examines the technical, environmental and economic feasibility and social acceptability of a range of specific beneficial uses of marine sediment.

A literature review is presented on the international dredging industry and outlines why dredging is an essential infrastructural activity. Current dredged marine sediment management techniques are presented and discussed.

An overview of the Irish dredging industry is …

Thermal Envelope Analysis Of Local Authority Low Rise Housing Based On Stock Aggregation Theory Using A Remote Feature Extraction Technique., James Pittam

Theses

Understanding the buildings thermal envelope is paramount to analysing existing problems which facilitate cold bridging and low surface temperatures. As no detailed housing stock database is in existence in Ireland which describes the geometrical configuration of the existing housing stock, and to create one would be a major challenge, this research set out to develop a high speed remote cataloguing and geometrical data extraction methodology to build such a database. Replacing traditional measurement methods with a remote method allows for the rapid extraction of fagade information. A remote surveying process is proposed named, the Virtual Survey Method, for the classification …
