The style of this report should be structured similar to a published / technical paper, and will be marked accordingly. The sections will be elaborated by Ash Ahmed during the lecture, the structure of the report should include:

a) Abstract (5%)

This section should be comprised of two parts, first part should be a very brief background to the report (the area of study) and the second part should be a summary of findings. This should be written in either one or two paragraphs max and should not consist of bullet points, figures, graphs, tables, etc. The length should be no more than 2/3 of a page 11 font size.

b) Introduction (30%)

This is the weightiest section of the report and should typically comprise of at least 6 pages covering:

i. Cement replacements in concrete (PCRs) ii. Recycled aggregates in concrete (RA)

In essence this section will focus on the sustainability of concrete from the perspective of partial cement replacements, recycled fine and coarse aggregates.

Introduction to concrete: properties & applications Composition of concrete: i.e. what its made from Manufacture Hydration of cement Sustainability of concrete - here initially mention the main issues, i.e. embodied CO2 of cement and construction and demolition waste. The suggested structure for this part is:

i) Partial cement replacements: (GGBS, PFA, metakaolin, silica fume and a mention of RHA, CCA, etc) ii) Recycled coarse aggregates (RCA, shredded tyre)

iii) Recycled fine aggregates (crushed glass, crumb rubber)

You must include (quote) at least two case studies / examples of the usage of either PCRs or RA’s in concrete. You can have two PCRs, two RCAs, etc. Marks will be awarded for appropriateness and quality of referenced work.

The final part of this section should have an ‘Introduction to Project’ summarising the aims and objectives of the report - about half page in length.

c) Experimental (10%)

Ensure in this section the following are included:

List of materials and apparatus

List of mixes

The procedure should include and be written in accordance to the relevant BS / EN standards found on My Beckett

Pictures / illustrations should be included as appropriate.

d) Results and Calculations (20%)

This section should include any relevant calculations, i.e. strength calculations.

Prepare appropriate graphs for each sample (mix), ensuring that the main mechanical properties are illustrated, as instructed. Calculations must be elaborated and clearly explained. Results should also be summarised in Table form. The format and style of graphs and tables should be similar as per research papers presented during the module lectures.

e) Discussion (25%)

(i) Compare the values calculated from your test data with the control mixes, with each other and most importantly intended mix design.

(ii) From your data / results, comment on the relative strength properties of the different recycled aggregates, pozzolanic/cement replacement concrete mixes.

In this section you must also use the theory covered during the sessions and compare with previously published work as appropriate - marks awarded for including other referenced work.

(iii) Discuss what this means in terms of the suitability of the respective concrete mixes for use under different loading and environmental conditions in the construction / civil engineering industry, i.e. what are the potential applications of the mixes based on the findings.

4

f) Conclusion (5%) This should be concise and succinct as per in published journal papers, i.e. a summary of the main findings. Can be either bullet points or in paragraph form. Should not exceed half page in length (normal text size).

g) References (5%)

Your citations, etc, whether a web source, text, conference or journal paper must be properly referenced. Can be Harvard or numbered style provided it is consistent.
