| 摘要： | Concrete makes up about 60% of the interstate system, with more than 100,000 bridges made of this sturdy and weather-resilient material. As we look to repair outdated and deteriorating roads, bridges and highways, a growing number of contractors are looking at ways to access concrete more quickly and cost-efficiently to keep the flow of traffic moving. Companies are enlisting the latest smart technology from the volumetric concrete industry to minimize risks while maximizing production and profitability through reduced downtime, increased efficiency, lowered materials costs, and consistent quality. A volumetric concrete mixer measures, mixes, and dispenses a precise amount of concrete from a single unit. Sand, stone, cement powder, water, and additives are each kept in its own bin to be mixed onsite and on-demand, eliminating the risks of too much or too little concrete, and hot loads (or ready-mix concrete that has begun its hydration process while still in the drum; hydration causes heat buildup in the concrete mix - thus a hot load). These are common culprits for loss of time and money. |
