| The project approach focuses on development of soil-like mixes that can be prepared at the power plant, transported to the deployment site and compacted using conventional road building equipment at about 25% to 30% of the cost of developing conventional concrete cattle feedlots. The developed mixes upon curing exhibit high strength (1,000 to 1,200 psi) making them resistant to abrasion. The materials have excellent durability characteristics and low swelling potential which have been the problems in previous similar studies. The environmental properties of the developed mixes have been evaluated and the leachates comply with Class I groundwater standards except for sulfates.; Field demonstrations for cattle feedlot construction using the developed materials were also conducted. A 6-7 tph mixing circuit was developed and demonstrated to produce approximately 175 tons of CCBs-based mix. This mix was used to construct a commercial 72-ft x 40-ft cattle feeding pad. |
