Putzmeister equipment aids in two record-setting continuous concrete pours within a month

A new record for the largest continuous concrete pour was set in Washington state when 13,690 cubic yards (10,467m³) of concrete was placed in 24 hours for the foundation of the 450-foot (137.16m) tall north tower at Lincoln Square.

A new record for the largest continuous concrete pour was set in Washington state for the foundation of the Lincoln Square South tower. However, it was short-lived, as less than a month later, the tower next to it beat the record. Vital to both high-profile concrete pours were Putzmeister placing systems, seven truck-mounted boom pumps and a high-pressure trailer pump — all supplied by Ralph's Concrete Pumping, Inc. of Seattle.

Cambridge researchers developing self-healing concrete

Researchers at the University of Cambridge are using microencapsulation technologies developed by Dolomite Microfluidics to develop self-healing construction materials. As highlighted in recent BBC News broadcasts, the Department of Engineering's Geotechnical and Environmental Research Group is developing microcapsules containing ‘healing' agents – such as minerals, epoxy or polyurethane – which can be added to building materials to allow self-repair of small cracks which develop over time. Dr Livia Ribeiro de Souza, a postdoctoral researcher in the group, explained: "Many composite building materials used in the construction industry – such as concrete – suffer fatigue over time, developing small cracks. We are hoping to overcome this problem by adding microcapsules filled with ‘healing' agents to the concrete before it is used. The idea is that, as cracks begin to form, they rupture the microcapsules, releasing their payload and stabilizing the material."

Road Dryer RD-1200 safely dries pavement in one pass for paving, surface treatments

Available as a simple-to-operate trailer- or truck-mounted unit, the RD-1200XT can be adjusted for 8-ft to 12-ft (2.4m to 3.7m) drying widths.

The RD-1200XT pavement-drying unit from Greenville, South Carolina-based Road Dryer, LLC, quickly dries asphalt and concrete pavement, allowing crews to pave or apply surface treatments or striping after just one pass. The unit, which blows heated air up to 300° F directly downward through multiple nozzles, eliminates the risk of "flying objects," and allows traffic to flow in nearby lanes — reducing congestion caused by traffic restrictions. Available as a simple-to-operate trailer- or truck-mounted unit, the RD-1200XT can be adjusted for 8-ft to 12-ft (2.4m to 3.7m) drying widths. Because it dries pavement on demand, it provides flexibility for contractors and government agencies to meet timetables by minimizing delays from weather- and project-related wet conditions.
