ARCT40950 Concrete Research

Academic Year 2021/2022

Most conventional concrete mixes, as specified by European Standards, are based on performance criteria for strength, durability, weight or other engineering characteristics. Architects are left with the choice of colour or surface texture. But our role could be greater than this, to consider the manner in which the mix of elements in concrete can be modified to influence other performance criteria, not specifically linked to engineering criteria, such as the environmental profile, the thermal properties of the mix, or even the proportion of reused aggregates. Our role can also extend to influencing where concrete is used and how it is detailed in an effort to minimize its environmental impact and facilitate its reuse at the end of a building's service life.

This module provides an overview of concrete and its properties, focusing on a different theme each year, with a view to understanding its use and potential in light of broader environmental design principles; to encourage a more integrated approach to building design, construction and performance.

The theme for study in 2020/21 is Designing Concrete Buildings for Disassembly & Reuse (DfDR)

Concrete has gathered a very bad reputation among designers concerned about the environment due to the considerable release of CO2 to the atmosphere that occurs during the production of conventional Portland cement. Coincident to this is the recognition of the potential of concrete to absorb CO2 from the atmosphere. Though a phenomenon long known to researchers in the field, until recently the ambition had been to reduce the absorption of CO2 as the carbonation of concrete, though beneficial for concrete, has detrimental effects on steel reinforcing. Given the current global ambition to reduce CO2 levels in the atmosphere a reconsideration of this natural tendency in concrete has occurred, which may have considerable implications for how it is used in architectural form. The subsequent reuse of concrete building elements, and their relative exposure to the environment, could facilitate this uptake of CO2 to offset the initial impact of cement production.

Learning Outcomes:

On completion of this course students should be able to;

Understand the environmental impact of material choices in the design of buildings.

Demonstrate a familiarity with environmental impact assessment methods for a material.

Understand how to frame performance objectives and a research hypothesis.

Demonstrate a knowledge of contemporary research in the field of concrete mixes, performance, design and construction, and reuse potential.

Demonstrate an ability to enhance a material's performance relative to its environmental impact through an iterative research, assessment and design process.

Indicative Module Content:

The module content varies by annual research theme. In principle content includes discussions on the environmental implications of material choices and the role of life-cycle analysis; understanding current trends and implications of cement and concrete production within an Irish and global context; reviewing concepts of embodied energy and carbon as well as methods of calculation and associated inventories of data; introduction to concrete mix design and the role of additives, admixtures and alternative forms of cement; contemporary research and case study projects on innovative concrete mixes and/or construction; and concrete construction assemblies.

The module typically includes a field trip to cement and/or precast concrete manufacturing facilities. There may also be workshops which will take place on Tuesdays following the midterm break where small sample projects are made based on research by individual and/or teams of students, which could form part of the final research report.

Feedback Strategy/Strategies

• Feedback individually to students, on an activity or draft prior to summative assessment
• Feedback individually to students, post-assessment
• Self-assessment activities

How will my Feedback be Delivered?

The first presentation and research summary will facilitate students to self-monitor and critically evaluate their own work relative to their peers and the discussion following the presentation. Written feedback will be provided to each student post-assessment. Students will be provided continuous feedback on the development of their research project, individually or as a group, in-class as their work progresses throughout the term. In-class review of the preliminary results will facilitate students to self-monitor and critically evaluate their own work relative to their peers and the project criteria. Written feedback will be provided to each student or team following completion of the workshop project. A final presentation of the research of each student or team of students will facilitate students to critically evaluate their own work relative to their peers and the project criteria. Written feedback will be provided to each student or team post-assessment on the final research report submitted.
