Mechanical Properties of Concrete with Recycled Concrete Aggregates – Lomboy, Cleary, MotlaghTHIS PROJECT REQUIRES LABORATORY WORK! –• You should be able to come to campus to do this work if you sign up for this
project. • Labs will have limited capacity so lab work will need to be performed outside of
clinic hours. You will need to have blocks of time available outside of clinic hours.• If you have questions about these requirements please contact Dr. Lomboy before
selecting this project as one of your options. [email protected]
WHAT YOU WILL BE DOING –Laboratory Activities• Measure the physical and mechanical properties of aggregates• Mix concrete • Test hardened concrete: compressive strength, flexural strengthRemote Activities• Literature survey on classification and testing of recycled concrete aggregates
Durability of Concrete with Recycled Concrete Aggregates – Lomboy, Cleary, Khan, Aragoncillo
