UNIVERSITY OF LIVERPOOL Overview CMT Technical Note // ENGG110 This technical note template is the entire submission for the CMT lab. Complete it by following the prompts and instructions, then submit it in Canvas using the Turnitin submission link. You will lose marks if you do not follow the instructions. In industry and research there are often very strict guidelines given for layout and page length of reports, so it is a useful skill to learn. Keep sections at the top of each page as indicated in this template. Your CMT lab technical note should not exceed 10 pages. The layout in this document is not exactly the same as it would be in a formal report, but the aim is to prepare you for writing reports later. You should use the feedback provided to improve your work. This technical note contains the following sections: Abstract 15% Part A: Concrete Making Results 25% Discussion 20% Part B: Concrete Testing Results Discussion 20% 20% Your submitted technical note will be marked by the laboratory teaching assistant (LTA) / Demonstrator for the CMT lab, normally within two weeks of the submission deadline. The module coordinator moderates the marking of the LTA. Feedback provided will include marks awarded for each section, with the technical note annotated with comments to explain where improvements can be made. You access your marked technical notes and feedback comments through the Grades interface in Canvas. 1 UNIVERSITY OF LIVERPOOL 1 Abstract/Summary CMT Technical Note // ENGG110 The Concrete Making and Testing Lab aimed to familiarize students with mix design and practical procedures for concrete preparation, casting, and testing. Over two weeks, students engaged in mixing materials, casting concrete samples, and conducting tests following industry standards. The first week focused on concrete making, including mix design, casting, and initial testing. The second week involved testing the cured concrete samples, analyzing results, and comparing them with control mixtures. Experimental procedures included mix design calculations, concrete casting, air-curing, and subsequent testing for compressive and tensile strengths. Results were compared against control mixtures to assess the performance of the concrete batches produced by each group. Main findings indicated variations in compressive strength compared to the control mixtures, highlighting potential differences in mix proportions or curing conditions. However, tensile strength remained consistent across both experimental and control batches. Conclusions drawn from the lab underscored the importance of precise mix design, proper curing, and thorough testing procedures in ensuring the quality and performance of concrete. Variations in water-cement ratios and aggregate types can significantly impact concrete properties, emphasizing the need for meticulous attention to detail in construction practices. Overall, the lab provided valuable hands-on experience in concrete preparation and testing, enhancing students' understanding of concrete technology and its practical applications in civil engineering. 10 2 2 UNIVERSITY OF LIVERPOOL Part A - Concrete Making (mixture analysis) 2.1 Results CMT Technical Note // ENGG110 0,5 Figure 1: A Simple Image to Indicate the Basic Form of the Experiment Fill out the correct values and justify according to: (BRE, 1997) BRE, (1997), Design of Normal Concrete Mixes, 2nd Edition: https://www.academia.edu/34172199/Design of normal concrete mixes BRE Concrete Mix Design Material (kg/m³) Control Mix Sand (0/4 mm) 990 Gravel (4/10 mm) 878 Cement CEM I 52.5R 380 Water 152 3
