Compressive Strength Of Concrete And Mortar Containing Fly Ash

View page
US Patent:
5853475, Dec 29, 1998
Filed:
Nov 20, 1996
Appl. No.:
8/737434
Inventors:
John W. Liskowitz - Belle Mead NJ
Methi Wecharatana - Parsippany NJ
Chai Jaturapitakkul - Bangkok,
Anthony E. Cerkanowicz - late of Livingston NJ
Assignee:
New Jersey Institute of Technology - Newark NJ
International Classification:
C04B 1400
C04B 1800
US Classification:
106705
Abstract:
The present invention relates to concrete, mortar and other hardenable mixtures comprising cement and fly ash for use in construction. The invention includes a method for predicting the compressive strength of such a hardenable mixture, which is very important for planning a project. The invention also relates to hardenable mixtures comprising cement and fly ash which can achieve greater compressive strength than hardenable mixtures containing only concrete over the time period relevant for construction. In a specific embodiment, a formula is provided that accurately predicts compressive strength of concrete containing fly ash out to 180 days. In other specific examples, concrete and mortar containing about 15% to 25% fly ash as a replacement for cement, which are capable of meeting design specification required for building and highway construction, are provided. Such materials can thus significantly reduce construction costs.

US Patent:
5772752, Jun 30, 1998
Filed:
Nov 20, 1996
Appl. No.:
8/737665
Inventors:
John W. Liskowitz - Belle Mead NJ
Methi Wecharatana - Parsippany NJ
Chai Jaturapitakkul - Bangkok,
Anthony E. Cerkanowicz - late of Livingston NJ
Assignee:
New Jersey Institute of Technology - Newark NJ
International Classification:
C04B 713
C04B 1404
US Classification:
106705
Abstract:
The present invention relates to concrete, mortar and other hardenable mixtures comprising cement and fly ash for use in construction and other applications, which hardenable mixtures demonstrate significant levels of acid and sulfate resistance while maintaining acceptable compressive strength properties. The acid and sulfate hardenable mixtures of the invention containing fly ash comprise cementitious materials and a fine aggregate. The cementitous materials may comprise fly ash as well as cement. The fine aggregate may comprise fly ash as well as sand. The total amount of fly ash in the hardenable mixture ranges from about 60% to about 120% of the total amount of cement, by weight, whether the fly ash is included as a cementious material, fine aggregate, or an additive, or any combination of the foregoing. In specific examples, mortar containing 50% fly ash and 50% cement in cementitious materials demonstrated superior properties of corrosion resistance.

Method For Increasing The Rate Of Compressive Strength Gain In Hardenable Mixtures Containing Fly Ash

View page
US Patent:
5681384, Oct 28, 1997
Filed:
Apr 24, 1995
Appl. No.:
8/427045
Inventors:
John W. Liskowitz - Belle Mead NJ
Methi Wecharatana - Parsippany NJ
Chai Jaturapitakkul - Bangkok,
Anthony E. Cerkanowicz - late of Livingston NJ
Assignee:
New Jersey Institute of Technology - Newark NJ
International Classification:
C04B 712
C04B 713
US Classification:
106710
Abstract:
The present invention relates to concrete, mortar and other hardenable mixtures comprising cement and fly ash for use in construction. The invention provides a method for increasing the rate of strength gain of a hardenable mixture containing fly ash by exposing the fly ash to an aqueous slurry of calcium oxide (lime) prior to its incorporation into the hardenable mixture. The invention further relates to such hardenable mixtures, e. g. , concrete and mortar, that contain fly ash pre-reacted with calcium oxide. In particular, the fly ash is added to a slurry of calcium oxide in water, prior to incorporating the fly ash in a hardenable mixture. The hardenable mixture may be concrete or mortar. In a specific embodiment, mortar containing fly ash treated by exposure to an aqueous lime slurry are prepared and tested for compressive strength at early time points.
