Concrete’s hectic morning shows a simple truth: plant to pour is a carefully managed journey, not just a delivery. From batching and mixing to transport, placement, and curing, every step affects the next. Concrete doesn’t wait. The instant water hits cement, the mix starts transforming, and there’s no undoing a batch that isn’t managed correctly. According to the National Ready Mixed Concrete Association (NRMCA), fresh concrete is a perishable product: it can lose slump and stiffen as time passes, especially in hot weather or during long hauls. Concrete doesn’t arrive at the jobsite in perfect stasis; it’s changing every minute as hydration progresses. Because of this, industry standards have long treated delivery with precision. ASTM C94 historically set a 90-minute limit from mixing to discharge to ensure concrete stayed workable and hadn’t begun to set. Exceeding that window often meant rejecting the load, a costly outcome when traffic or onsite delays interfered. Today, admixtures and updated standards allow more flexibility. If slump, temperature, and air content remain within spec, producers and contractors can extend delivery times, sometimes beyond 120 minutes. But the principle remains: concrete moves steadily from fluid to solid, and that transformation must be carefully managed. This blog…
Giatec continues to uphold the value of bridging the gap between academic research and sustainable construction on the jobsite. Every year, we recognize civil engineering students, researchers and faculty across Canada and the U.S. with the Giatec Best Paper Award for Sustainability in Construction. Below is a summary of the winning 2025 paper submitted by Dr. Soroush Mahjoubi and his team, “Data-Driven Material Screening of Secondary and Natural Cementitious Precursors.” Want to see how you can share your research for the 2026 Giatec Best Paper Awards? Learn more here! Research Background Concrete is the most widely used manufactured material on the planet, and because we produce so much of it, it has a significant carbon footprint. Most of those emissions come from clinker, the binder in cement that requires energy-intensive kilns and releases CO₂ when limestone is calcined. For decades, the industry has replaced a portion of clinker in mixes with lower-carbon materials such as coal fly ash and steel slag. However, as coal plants shut down and steel recycling ramps up, supplies of these traditional substitutes are shrinking. To continue reducing emissions by replacing clinker, the industry needs new supplies of clinker replacements. New research from the MIT Concrete Sustainability Hub and Olivetti Group aims to mitigate this problem with the help of artificial intelligence (AI) and machine learning (ML). The team used large language…
Dubai’s Law No. 7 of 2025 has introduced a new contractor classification system that redefines how contractors operate in the emirate. Dubai Municipality’s digital registry records and links every aspect of a contractor’s performance to classify them under its new, publicly accessible contractor classification law. The latest challenge for most contractors lies in maintaining up-to-date quality documentation and real-time compliance records. Dubai Municipality’s digital registry connects every aspect of a contractor’s operational performance, meaning testing delays and documentation gaps can affect classification standing. According to the AECOM Middle East Review 2025, regional construction projects experience average delays of 83% beyond schedule, with traditional 28-day concrete strength testing remaining a key contributing factor. In this blog, let’s explore how real-time concrete monitoring using the maturity method helps contractors eliminate testing bottlenecks, maintain schedules, and demonstrate quality control competency under Law No. 7. Understanding Dubai’s Law No. 7 of 2025 Issued on July 8, 2025, Law No. 7 establishes a unified contractor classification system managed by Dubai Municipality. This new framework represents a complete restructuring of how contractors are evaluated and authorized to operate in Dubai. Contractors have one year from the law’s effective date (six months after its publication in the Official Gazette) to regularize their status. Dubai Municipality may extend this period to two years in certain cases, though early compliance remains the recommended approach. The Penalty Structure The regulation establishes strict requirements for maintaining classification status. Contractors can face penalties of up to Dh200,000, potential…
