Filed:

Feb 9, 2007

Appl. No.:

11/673391

Inventors:

Edward K. Rice - Los Angeles CA, US
Eric Bescher - Los Angeles CA, US
David Flax - Laguna Niguel CA, US
Daniel Goods - Livermore CA, US
Kyle de Bruyn - Anaheim CA, US

International Classification:

C04B 14/38

US Classification:

106644, 106713, 264333, 264DIG 43

Abstract:

Synthetic fibers, such as polypropylene fibers, are mixed in a shrinkage compensating concrete to provide restraint in lieu of conventional steel reinforcement used in a shrinkage compensating concrete. While the synthetic fibers have a low elastic modulus and low strength, they act to restrain expansion of the concrete in the same way that conventional steel rebar does. In addition, only a small amount of the synthetic fibers are needed to restrain the expansion. As a result, shrinkage compensating concrete can be used in more varied applications, and can be provided more quickly, easily and inexpensively. Construction time requirements and expenses of concrete structures are correspondingly reduced.

Filed:

May 6, 2011

Appl. No.:

13/103029

Inventors:

Edward K. Rice - Los Angeles CA, US
Grant M. Kao - Rowland Heights CA, US
Eric P. Bescher - Los Angeles CA, US

International Classification:

C04B 14/00
C08K 3/34
C04B 7/32

US Classification:

106643, 106692, 524 3

Abstract:

A calcium sulfoaluminate-based concrete with a permeability of less than 1000 Coulombs. Rapid-setting low chloride-ion permeability calcium sulfoaluminate (CSA) cements and concretes include CSA and a suitable polymer such as a sol-gel derived, organic-inorganic, silica based hybrid coating solutions of polystyrene-butylacrylate polymers containing active silanol groups protected by hydroxyl groups containing polyalcohol, or other polymers. Such polymers may be added as powders or as liquid in the finish mill. Other rapid-setting low chloride-ion permeability (CSA) cements and concretes include CSA with selected particle size distributions, and do not require use of any polymer. These CSA cements and concretes have low chloride-ion permeability, high early strength, fast setting times, low-shrinkage, and high freeze-thaw resistance.

Abstract:

Microparticles having crystalline needle or rod-shaped structures of, for example, an ettringite mineral grown and attached radially from their surface. A method including nucleating and growing crystalline needles/rods from the surface of a particle in the presence of a solution of calcium, sulfur, and aluminum such as calcium sulfoaluminate, lime and calcium sulfate is described. One example is the radial growth of ettringite needles on the surface of fly ash particles in calcium sulfoaluminate-based cement paste and concrete.

Appl. No.:

13/840796

Inventors:

Edward K. Rice - Los Angeles CA, US

International Classification:

C04B 11/30

US Classification:

106788, 4273722

Abstract:

A shrinkage compensating concrete does not require restraint. The expansive forces developed during hydration compensate for concrete shrinkage, obviating the need for any added internal or external restraint element. Using this new shrinkage compensating concrete, substantially crack-free slabs may be built without using restraining steel bars, fibers, or other separate restraining element. The shrinkage compensating concrete includes a cement that develops internal expansive forces that never exceed the tensile strength of the concrete, such that the internal expansion compensates for the concrete shrinkage. The expansive cement may be an ASTMS, M or S cement, or other expansive cements may also be used.
