| titleOfInvention | Concrete optimized for high workability and high strength to cement ratio |
| abstract | A concrete composition having a 28-day design compressive strength of 3000 psi and a slump of about 5 inches is optimized to have high workability and a high strength to cement ratio. The concrete composition contains about 340 pounds per cubic yard hydraulic cement (e.g., Portland cement), about 102 pounds per cubic yard pozzolanic material (e.g., Type C fly ash), about 1757 pounds per cubic yard fine aggregate (e.g., FA-2 sand), about 1452 pounds per cubic yard coarse aggregate (e.g., CA-11 state rock, 3/4 inch), and about 294 pounds per cubic yard water (e.g., potable water). Workability and strength to cement ratio were increased compared to one or more preexisting concrete compositions having the same 28-day design compressive strength and similar slump by optimizing the ratio of fine aggregate to coarse aggregate. The concrete composition is further characterized by high cohesiveness, resulting in relatively little or no segregation or bleeding. |
