Repair cracks in concrete pavement and more
The Roadware Microdoweling concrete repair system features needle tip injectable polyurethanes that penetrate deep into concrete surfaces and cure in as little as 10 minutes. Repairs can restore aggregate interlock in loose joints and can structurally bond slabs back together without becoming brittle. Roadware Inc. www.roadware.us.
Automatic coupler system
The Likufix is a quick coupler with an automatic hydraulic coupling system. It is based on two patented connecting components attached to the existing Liebherr quick coupler adapter and the hydraulic power attachment. With it, hydraulic excavator operators can change hydraulic add-on tools in seconds without leaving the cab. All hydraulic connections are made automatically and use a hydro-mechanical seal to prevent oil leaks and prevent contamination of the hydraulic connections. The system can be retrofitted to existing Liebherr hydraulic excavators with service weights between 26,450 lbs. and 88,160 lbs.

Power train protection
The Power Train Saver protects trucks of all sizes from over-torque damage. Installed into the existing drive shaft, it works on a system of three shear pins, called torque fuses, that are engineered and tensile tested to precisely shear just prior to the power train breaking point. When over-torque occurs, the torque fuses shear, preventing damage to the drive shaft, axles, gears, and differentials. After shearing, the unit freewheels on an internal support bushing and pin that keeps the drive shaft in place rather than falling to the ground and causing other damage. Repair is just a matter of backing off the nuts and replacing the broken torque fuses. Sonnax Industries. www.sonnax.com.
Featuring colorful charts and easy-to-read graphs, Foundation Software's Executive Dashboard allows users to view and analyze high-level data, then effortlessly drill down into additional reports for more detailed information. Users can see on one screen a summary of their latest job cost, accounts payable, accounts receivable, and other financial data. A scrolling ticker at the bottom of the screen contains key aggregate data. Foundation Software. www.foundationsoft.com.
Access ACI Certification training programs online
The eLearning program allows concrete engineers, designers, contractors, educators, and students to access ACI Certification training programs and numerous other technical topics online, 24 hours a day, 365 days a year. Users can participate in structured online education and training programs and earn CEUs from anywhere in the world, at any time, providing a convenient and efficient way to train employees yourself. Training modules involve directed self-study with the assistance of reference documents, learning exercises, educational videos, and a final exam to evaluate the participant's understanding of the topic.

Dual technology waterstop
Bentoject combines two technologies - a hydrophilic waterstop and a grout injection tube - in a single product that stops water intrusion through cold joints in belowgrade concrete structures. A reinforced spiral steel wire prevents tube collapse during concrete placement. This is covered with a filtering membrane to form a permeable tube for future grout injection. A bentonite rubber outer skin covers the membrane and swells on contact with water, filling the cold joint like a standard hydrophilic waterstop. Any voids can be injected through the tube with chemical grout. DeNeef Construction Chemicals Inc. www.deneef.com.
Column Cast is a reusable sleeve and foam insert system that produces detailed columns easily and inexpensively with little or no waste. Steel buckles adjust and hold the form snugly, and, if damaged, can be easily removed and replaced. The cut foam inserts can either be cut inexpensively for one-time use or coated so that they can be removed intact and reused for multiple pours. Column Form Technology. www.columnformtechnology.com.
Surfacing and dust collection guards
Three new families of patented grinder attachments offer angle grinder users new levels of functionality, comfort, and safety. SG-Series attachments are designed for concrete surfacing applications where dust removal is a must. The DC-Series attachments provide dust removal and collection in masonry cutting applications. CG-Series cutoff guards are ideal for applications where safety is a concern, such as exterior concrete cutting, grinding, and metal cutoff applications. Compatible with all Bosch One Touch Guard System 4 1?2-in. through 7-in. angle grinders, the new attachments install without tools. Bosch Power Tools. www.boschtools.com.
Electric diamond cutters
Hilti's DCH 230 and 300 Electric Diamond Cutters, designed exclusively for cutting, feature a 2.6-kw motor and new cutting depth adjustment mechanism. While conventional angle grinders both grind and cut to little more than 2 in., these cutters cut to 3.4 and 4.7 in. respectively - almost twice as deep. Hilti Smart Power regulates motor power and pressure to suit the material being cut - even the toughest, thickest materials such as reinforced concrete, granite curbstone, slabs, bricks, metal beams, and steel pipes. Direct attachment of a vacuum cleaner facilitates nearly dustless cutting. Hilti Inc. 918-252-6265. www.hilti.com.
ATTENDEES' AND EXPERTS' CHOICE
Elemix concrete additive consists of innovative polymeric spheres specially formulated for use in concrete. Distributed uniformly, it provides lighter weight, improves energy efficiency by decreasing thermal conductivity, and enhances durability in structural and non-structural applications. Its closed cell honeycomb-like interior structure gives concrete the ability to absorb energy, which reduces cracking and improves energy efficiency. As a manufactured sphere, Elemix additive reduces variability in concrete mixtures. Syntheon Inc. www.elemix.com.
