I was privileged to present my research work at the 13th International Society for Concrete Pavements conference in Minneapolis. A very informative conference it was. On top of that I had an opportunity to meet with the most knowledgeable people in the world of concrete pavement. Great network. I extend my gratitude to my advisor John Kevern, PhD, PE, F.ASCE, FACI, LEED AP and to Dr. Tara Cavalline for giving us the opportunity to share the work.

I am pleased to share our latest publication on concrete curing. This study used a low-cost and non -destructive resistance-based technbique to evaluate the effectivenss of curing compound applications in real-time. I extend my gratitude to John Kevern, PhD, PE, F.ASCE, FACI, LEED AP Peter Taylor Dan King , and Transportation Research Board for your contributions towards the sucess of this work. The article can be found using the link below. Enjoy Reading! https://lnkd.in/gTb2BrXC

Please check out the latest International Society for Concrete Pavements April student research spotlight to find out about my research on curing of Rigid pavement.
The ISCP “STUDENT RESEARCH SPOTLIGHT” for April 2024 is etienne Beya Nkongolo, a Ph.D. student at the University of Missouri-Kansas City (Kansas City, USA) Etienne is currently working on timely and uniform application of curing compound on concrete pavements Read more at: https://lnkd.in/d4n9tuB5 ISCP would like to feature a “STUDENT RESEARCH SPOTLIGHT” each month, or every other month. If you would like to nominate a student, or if you are a student and would like to nominate yourself or a colleague, please send ISCP an email to: newsletter@concretepavements.org #concrete #concretepavement #pavements #research

Things we like to see. It is worth your time reading it.
Hot off the presses, a teaser for big things to come for concrete curing. https://lnkd.in/gpK9Y-9A

I had a privilege to present my PhD research work at the 2024 Transport Research Board 2024 Annual meeting in Washington DC. It was a great experience hearing, exchanging and learning from the most experienced figures in Transportation world. Big thanks to my Advisor John Kevern, PhD, PE, FACI, LEED AP for making it happen, and to Dan King and Peter Taylor for their collaborations.

Here are some types of cracks in reinforced concrete: 1. 𝐏𝐥𝐚𝐬𝐭𝐢𝐜 𝐬𝐡𝐫𝐢𝐧𝐤𝐚𝐠𝐞 𝐜𝐫𝐚𝐜𝐤𝐬: These cracks are often shallow, irregular. They occur when the concrete is still in its plastic state and is drying too quickly. 2. 𝐃𝐫𝐲𝐢𝐧𝐠 𝐬𝐡𝐫𝐢𝐧𝐤𝐚𝐠𝐞 𝐜𝐫𝐚𝐜𝐤𝐬: These are hairline cracks that run parallel to each other and can occur anywhere in the concrete as it dries and shrinks. 3. 𝐓𝐡𝐞𝐫𝐦𝐚𝐥 𝐜𝐫𝐚𝐜𝐤𝐬: This type of cracks is caused by temperature changes in the concrete. Extreme heat or cold can cause the concrete to expand or contract, resulting in cracks. 4. 𝐒𝐞𝐭𝐭𝐥𝐞𝐦𝐞𝐧𝐭 𝐜𝐫𝐚𝐜𝐤𝐢𝐧𝐠: These occur when the soil beneath the concrete settles or shifts, causing the concrete to crack and become uneven. 5. 𝐒𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐚𝐥 𝐜𝐫𝐚𝐜𝐤𝐬: These are cracks that occur due to overloading or inadequate design or poor materials or poor construction, in this case the applied loads exceed the capacity of the concrete to resist. Structural cracks typically exceed 0.3 mm, and may continue to widen over time. Structural cracks may include: Shear cracks, Flexural cracks, Shear/flexural cracks, Torsion cracks. 6. 𝐂𝐨𝐫𝐫𝐨𝐬𝐢𝐨𝐧 𝐜𝐫𝐚𝐜𝐤𝐬: These are cracks caused by expansion of the reinforcement steel inside the concrete due to corrosion. 7. 𝐂𝐫𝐚𝐜𝐤𝐬 𝐝𝐮𝐞 𝐭𝐨 𝐀𝐥𝐤𝐚𝐥𝐢-𝐚𝐠𝐠𝐫𝐞𝐠𝐚𝐭𝐞 𝐫𝐞𝐚𝐜𝐭𝐢𝐨𝐧 (𝐀𝐀𝐑): This is a chemical reaction that occurs between the alkaline cement paste and certain types of aggregates in the concrete, resulting in a gel-like substance that can cause expansion and cracking over time. AAR can include alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR). .......................................................................

Great experience it was.
Had a great trip doing sustainability and resiliency planning for the Western Cape in South Africa looking at pathways for persistent pollutants in groundwater recharge. Pretty tough duty having to trace water sources up the watershed 😆. Made sure to talk carbon neutrality and low-carbon concrete solutions. University of the Western Cape, Cape Peninsula University of Technology, and Stellenbosch University are always great hosts.
