Solidia offers a low-lime containing calcium silicate cement (CSC) that emits 30 percent less CO₂ during the production process compared to ordinary portland cement. CSC can consume up to 300 kg of CO₂ per ton of cement during the curing process of the concrete resulting in up to 70 percent reduction in CO₂ emission. "Finished Solidia Concrete products can contain up to 7 weight percent of sequestered CO₂, although it is subject to the partic- ular application," reported Dr. Sahu. "Solidia uses carbonation instead of hydration, so we are not only reducing CO₂ in the atmosphere by sequestering in concrete products, but we are also able to recycle and save water used in the process." Dr. Sahu was joined by research partner Jason Weiss, Ph.D., professor of civil engineering at Oregon State University, who presented a paper entitled "The Role of Alternative Cements in Limiting Joint Damage Due to Calcium Oxychloride." Dr. Weiss reported test results demonstrating the superior per- formance of Solidia Cement-based concrete in freeze thaw environments with de-icing salts. "Solidia Cement and Concrete address pressing concerns facing the cement and concrete industry and the world at large," said Dr. Sahu. "The production of cement, which is used to make concrete, is responsible for 3 to 5 percent of total global carbon emissions, water scarcity is becoming more of an issue, and the rise of urbanization and industrialization is placing increased stress on aging infrastructure the world over. Solidia Technol- ogies offers a profitable solution to all these challenges, with products that have proven to be stronger and more durable than traditional portland cement-based products." The FHWA supports Solidia with a multi-year cooperative agreement to examine Solidia Concrete in transportation infrastructure applications. This joint program includes inde- pendent testing of Solidia Concrete at the Turner-Fairbank Highway Research Center.

The SmartBob HM – for horizontal mount – can be used when it is not possible to install the sensor on the top of the bin. The SmartBob HM features a rigid extension that is cus- tom-made from 12- to 36-ft. long to install on the side of the bin through a 4-ft. opening. Precise level measurements are taken at pre-determined time intervals at a location directly below the probe to continuously monitor the inventory of material inside of the bin. The SmartBob HM continuous level sensor works like an automated tape measure, but eliminates the need to climb bins for manual measurements to reduce the risk of acci- dents dents in the workplace.

It is listed for Class II, Groups E, F, & G and enclosure types NEMA 4X, 5 and 12, ensuring the sensor is safe to use in locations where combus- tible dust may be present. It can be used in a mixed network of SmartBobs that are installed on the top of the bin or are monitoring other materials for a complete inventory man- agement solution.
