| 68 | CONCRETE HAVING HIGH WORKABILITY THROUGH CONTROL OF FINE-TO-COARSE PARTICULATES RATIO | US11961708 | 2007-12-20 | US20090158965A1 | 2009-06-25 | Per Just Andersen; Simon K. Hodson |
| 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 1500 psi. 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 8500 psi, or 58.6 MPa), the fine particulates fraction comprises about 50-75% by volume of total particulates. For high strength concrete (>8500 psi, 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. | ||||||

| Concrete compositions have a fine-to-coarse aggregate ratio optimized for increased workability with minimal segregation and bleeding. 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 1500 psi. Workability is improved by minimizing the viscosity as a function of the aggregate content, while minimizing segregation and bleeding. To improve workability, the concrete compositions include between 45% and 65% fine aggregate and between 35% and 55% coarse aggregate as a function of total aggregate volume. For relatively low strength concrete (1500-4500 psi), the fine aggregate is 55-65% of the total aggregate volume. For medium strength concrete (4500-8000 psi), the fine aggregate is 50-60% of the total aggregate volume. For high strength concrete (>8000 psi), the fine aggregate is 45-55% of the total aggregate volume. Overall workability can be maintained or improved even if slump is decreased. | ||||||

| Water-soluble, biologically degradable copolymers based on polyamide are described which contain at least one grafted side chain composed of aldehydes and sulfur-containing acids and salts thereof and optionally at least one compound from the series ketones, aromatic alcohols, urea (derivatives) and amino-s-triazines. Natural polyamides such as caseins, gelatins, collagens, bone glues, blood albumins and soya proteins as well as degradation products thereof and synthetic polyamides such as polyaspartic acids and copolymers of aspartic and glutamic acid are used as preferred polyamide components. These copolymers are obtained primarily by graft polymerization at temperatures between −10 and 250° C., preferably in the presence of a solvent such as water or by thermal drying and they are used in particular as flow agents or water retention agents for inorganic binders and pigments especially in combination with hydraulic binders they only have a very slight setting-retardant effect. | ||||||
