HNTB – Kansas City, Mo., was selected to deliver Nebraska’s first design/build project: at 3,000 ft., one of the longest pedestrian bridges ever built. To ensure long-term durability through years of Midwestern seasonal changes, the firm chose Type K shrinkage-compensating grout made with Komponent® cement additive to fill the channels that house post-tensioned cables.
CSA cement is a proven technology for the underground construction industry. The fast set time, high strength, low porosity, high chemical stability and sulfate resistance make it a material uniquely suited for underground repairs, shotcrete and other applications as needed.
A non-shrink grout was required to secure the piles to avoid voids that might absorb water in the nail tubes and cause corrosion of the steel. Shrinkage-compensating Type K grout was specified to meet these needs and mixed in ready-mix trucks for the 366-ft.-by-50-ft. project area.
Six curved and submerged stainless steel gates are helping control water releases from a new spillway. A 7000-psi non-shrink grout made with Komponent shrinkage-compensating cement additive is ensuring a durable, watertight seal.
Today’s design, engineering, and construction professionals face a host of complex construction challenges. A vast majority of construction projects incorporate the use of concrete for its versatility, durability, and sustainability. This article discusses how Type K shrinkage-compensating cement improves the concrete by overcoming drying shrinkage cracking, reducing permeability, and improving sulfate resistance.
