This paper follows the hydration of both portland cement and tricalcium silicate pastes between 30 min and 16 h of hydration. In-situ fast X-ray computed tomography (fCT) was used to make direct observations of the air-filled void formation in w/s of 0.40 to 0.70 with a micron resolution. The results show that over the first hour of the ...

Known formally as Portland Limestone Cement or PLC, low-carbon cement is a blended product containing higher limestone content. Using more limestone creates less "clinker," the basic component in nearly all types of cement, in the manufacturing process; generating less carbon dioxide as a result.

Construction of the interstate highway system began in 1956. This U.S. network of highway consists of more than 41,000 miles with 790 miles in Iowa. There have been many benefits of the controlled access roadway, but probably the most significant is the improved safety for the motorist. In Iowa, we have always endeavored to utilize quality locally available materials in our construction using ...
