Evaluation of European rapid-setting concrete products for airfield repairs

The USAF is assessing European cementitious repair products to certify them for spall and crater repairs on airfield pavements. As part of this ef-fort, the USAF asked the US Army Engineer Research and Development Center (ERDC) to evaluate and test three European-manufactured rapid-setting materials at the Silver Flag Exercise Site, Ramstein Air Base, Germany. ERDC evaluated and tested two cementitious products manufactured by Concretum, a company in Switzerland (country code CH), and one product, AC Concrete Rapid Set, from CTS Cement Manufacturing Corporation. The product was provided by Korodur International, a German (country code DE) distributor. Rapid pavement repair activities are critical to economically and efficiently sustaining airfield operations with existing pavement infrastructure. Repairing spalls and craters in Portland cement concrete airfield pavements will help lower repair costs from aircraft impact damage and prolong the service life of the pavement, ultimately saving money over its lifespan. Numerous partial-depth spall and full-scale crater repairs were constructed along existing inner and outer slab joints and backfilled with rapid-setting cementitious repair products following manufacturer mixing requirements.
