The Thailand Concrete Association (TCA) collaborated with the department of civil and environmental engineering at Srinakharinwirot University to deliver the latest insights into the selected topics. Taking place on September 16–17, 2023 (prior to the ICCC2023 main program), the pre-congress courses allow attendees to explore a particular subject area in more detail and depth. It will be held at the faculty of science at Srinakharinwirot University (Prasanmit Campus). Places are limited, so book early to avoid disappointment. Registration for these courses is now available for delegates to select while registering for the ICCC2023 (the fee for these courses is separate from the ICCC2023 main program fee and must be purchased as an add-on during the registration process).
