16 LC DBM A recent move to a far larger location by TUFX-FORT Manufacturing Inc., a manufacturer of high quality, ergonomic wheelbarrows, coupled with a $2.5 million plant re-layout for improved throughput and quality control, spurred new product development such as cost-effective, patented, flat free wheel options, and a new fulfillment style warehouse operation – reducing lead times from five weeks to one day. A number of hardscape industry trade associations collaborated to develop a new online pavement design tool for pav - ing professionals. PavementDesigner.org is free of charge, brings some of the in - dustry's best pavement design programs together on a single website, offers cloud storage and retrieval and promises automatic updates and improvements. https://pavementdesigner.org Manufactured through a proprietary process, Visage® new two-piece wall system by Tremron, can deliver up to five finished faces per unit. In addition, the product requires minimal cutting and uses a proven pin connec - tion system for ease of installation. It is currently available in the Southeast but will be expanded geographically through Keystone Hardscapes® of the QUIKRETE® Company. The American Concrete Institute has released the 2018 ACI Collection of Concrete Codes, Specifications, and Practices (formerly known as the Manual of Concrete Practice). Besides containing nearly 50 codes and specifications, the manual covers concrete design, construction, repair, materials, inno - vation and specialized applications, and also includes information on masonry. It is offered as an online subscription, a USB drive, and an eight-volume set of books. Individual volumes are also available, as is online access for multiple users. https://tinyurl.com/ybfyeta7 The water and oxygen that get in through cracks in concrete threatens steel rein- forcement with rusting and eventual failure. Researchers from universities in New York and New Jersey are developing a self-healing concrete by mixing dormant spores of a fungus into it. With the presence of water and oxygen, the fungus is reactivated and begins to grow, creating calcium carbonate as a byproduct, which would fill in the cracks. Once filled, the fungi would go dormant again. https://tinyurl.com/yb4bvtju . A group at MIT attempted to make concrete stronger by adding bits of plas - tic that were exposed to harmless gamma radiation, which separate research showed created a stronger crystalline structure in the plastic. Concrete samples were produced with no plas - tic, plastic with no radiation, and plastic exposed to high and low levels of radiation. Compression tests found that samples without plastic were stronger than those with regular plastic, but not as strong (by 20%) as those with irradiated plastic.
