The Royal Air Force (RAF) has selected FIREROK cement from CERATECH for application in its V-22 Osprey aircraft project, which is performed at RAF Mildenhall located in Suffolk, England. The high thermal resistant, durable cement will be used for the construction of Osprey’s concrete apron and hardstand.
Specialty Products, a general contractor for the RAF project, has identified that the FIREROK cement possessed major characteristics that meet demanding job specifications. The project required concrete that is capable of withstanding 550°F temperatures. The President of Specialty Products, Tres Swann, stated that their team evaluated various products, which can meet this requirement and finally found that FIREROK was the only product that met and surpassed specifications. Other requirements of the project include the capability to withstand hydraulic fluids and other hydrocarbons and corrosion resistance property, added Swann.
Portland cement concrete can withstand temperatures only up to 250°F and it starts to break down, when it is exposed to temperatures above the specified value. While, the FIREROK durable cement from CERATECH withstands intermittent temperatures ranging up to 1850°F and maintained temperatures up to 570°F, without high loss of strength. The durability of FIREROK delivers a lifecycle, which is 3-5 times longer than portland cements.
The entire range of cements by CERATECH includes 95% of recycled fly ash and 5% of renewable materials. These cements include a dense crystalline structure, which helps to significantly increase thermal resistance capability. In addition, the structure decreases permeability, thus making the cements more durable in corrosive and caustic chemical environments. The production of CERATECH’s cements does not produce carbon dioxide, whereas portland cement production generates nearly one ton of carbon dioxide for every ton of production. CERATECH’s cements are offered as a bulk cement, as well as in super sacks and as a package of concrete repair mixes.
