Kestrel 4300 Construction Weather Tracker
Kestrel released the 4300 Weather Tracker, which measures relative humidity, temperature, and wind speed and displays an estimated evaporation rate. Evaporation rate is an environmental indicator that concrete contractors use to avoid plastic shrinkage cracks in concrete. The meter stores the time and environmental data, and the contractor can later upload the data to a PC with the Kestrel PC Interface, allowing long-term storage, in-depth analysis, and detailed charting. Every Kestrel is individually calibrated to NIST-traceable standards and comes with a Certificate of Conformity. Kestrel 4300 features a waterproof case; a backlit display; customizable data storage of up to 3600 data points; a humidity sensor that can be recalibrated in the field; a user-replaceable impeller; a user interface that can be set in English, French, German, and Italian; and a 5-year warranty.

Mako Screed Support Sytems
Mako Screed Support Systems offers contractors a method to maintain the finished elevation of concrete while increasing F-numbers and reducing production time. It can be useful for projects such as slab-on-ground, elevated decks, flat floors, bridges, thickened slabs, and leveling subgrade. The system contains a driver and FinCap screed support, which allows one person to set multiple FinCap screed support locations. The FinCap fits mounting structures from 3/8 to 5/8 in. (10 to 16 mm) and supports a nominal 1.5 in. (40 mm) schedule 40 or higher screed pipe.
Primekss PrimeComposite Jointless
Primekss introduced Prime Composite Jointless, a technology used to create steel fiber-reinforced nonshrink concrete flooring without joints. Flooring areas can be jointless up to 650,000 ft2 (6000 m2). Joints can slow down lifttruck traffic, so selecting jointless floors allows for increased production. Jointless floors can also improve durability and functionality of floors. There is no requirement for filling and maintaining joints, and racks or equipment can be placed where needed.
TEC Fast-Set Deep Patch
Tec® Fast-Set Deep Patch is a self-drying cement-based underlayment. It is ready for most floor coverings in approximately 1 hour. This formula is designed for deep fills, ramping and leveling concrete, and application on plywood subfloors. It can be used for fills up to 1.5 in. (38 mm) in a single application. It can be placed with a steel trowel, float, or screed. Fast-Set Deep Patch provides a compressive strength of 4200 psi (29 MPa) and contains zero volatile organic compounds.

EnStyro EPS and XPS Shredder
EnStyro shredder was designed to produce concrete aggregate from polystyrene foam. It rips expanded polystyrene and extruded polystyrene into smaller pieces that pass through a screen before collection. The screens are removable and range from 1/8 to 1.5 in. (3.2 to 38.1 mm). The shredder rips rather than shears, allowing particles to have different shapes and sizes while achieving the lowest possible density. It features an exhaust blower that transports materials through the shredder and into the collection bag.
Hilti POS 150 and 180 Robotic Total Stations
Hilti introduced the POS 150 and 180. Plans and work points are stored in memory in the station. The compact controller is in permanent wireless connection with the station, providing direct access to all the functions and allowing one-person operation. The stations can be used for 3-D layouts, measuring offsets and slopes, and direct area measurement. Hilti's calibration service helps ensure reliability and accuracy. Both stations are covered by Hilti's lifetime service plan and a service agreement that includes 2 years of zero-cost coverage.
Dually Reinforcing Bar Support
LTM Concrete introduced Dually, a reinforcing bar support that allows bars to be supported at seven different elevations. It can be used in footings, slabs, walls, and post-tensioning projects. Dually features a wide base for stability on uneven surfaces and a wide opening that allows concrete to flow through.
