# Top 10 World Record Breakers in Concrete

## This week, we've compiled our top 10 record-breakers in concrete. From old to new, this list will give you an idea of the best of the best in the world of concrete!

The earliest recordings of concrete structures date back to 6500BC by the Nabataea traders in regions of Syria and Jordan. They created concrete floors, housing structures, and underground cisterns. Contrary to popular belief, the Ancient Romans were not the first to create this innovation and did not implement this until around 500 years later, though they were the first to use the material widespread and at a much larger scale.

### 4. Largest Concrete Pour

This year Safari Group, Mazsaya Consulting Engineers, Oscar Construction Co Ltd, and CONMIX Ltd. completed the largest continuous concrete pour at 20,246 m³ (26,480.76 yd³). The pour took place from April 13-16, 2017 in Sharjah, United Arab Emirates, and was poured for a new mall project. The pour lasted 62 hours and took 140 individual trucks to deliver the concrete. Between four construction companies, there were approximately 622 people on the job.

LafargeHolcim supplied 1.3 million m3 of high-tech concrete for various sections of the tunnel.

### 8. Heaviest Concrete Structure

Coming in for a second round is the Three Gorges Dam from Hubei province, China, holding the title of the world’s heaviest concrete structure, weighing in at 144,309,356,753.51 pounds… of concrete that is!
