	"Roller-compacted concrete (RCC) and soil cement have been used in dam [[construction]] since the late 1970s. These materials are similar since they both have zero-slump consistency and are placed and compacted with equipment typical of earth-moving or paving operations. The use of RCC and soil cement usually results in a shorter construction schedule due to higher production rates compared to conventional or [[Mass Concrete\|mass concrete]] construction. A shorter construction schedule minimizes the hydrologic risks involved with dam construction and allows the [[contractor]] to reduce contingency costs for potential flood damages." <ref name="FEMA1015">[[Technical Manual: Overtopping Protection for Dams (FEMA P-1015)\| Technical Manual: Overtopping Protection for Dams (FEMA P-1015) ~~(Federal Emergency Management Agency~~, 2014)]]</ref>		"Roller-compacted concrete (RCC) and soil cement have been used in dam [[construction]] since the late 1970s.
