| titleOfInvention | Concrete having high workability through control of fine-to-coarse particulates ratio |
| abstract | Concrete compositions have a fine-to-coarse particulates ratio optimized for decreased viscosity and increased workability. The concrete compositions include at least water, cement, coarse aggregate, and fine aggregate and have a slump of at least 1 inch and a 28-day compressive strength of at least about 1500psi. Workability is improved by minimizing the viscosity as a function of the particulates ratio. To improve workability, the concrete compositions include between 49-85% fine particulates (e. g., cement and fine aggregate) and between 15-51% coarse particulates as a percentage of overall particulates volume. For normal strength concrete (up to about 8500psi, or 58.6 MPa), the fine particulates fraction comprises about 50-75% by volume of total particulates. For high strength concrete (> 8500psi, or 58.6 MPa), the fine particulates fraction comprises about 56-85% by volume of total particulates. Overall workability can be maintained or improved even if slump is decreased. |
