Benefits of technology

The present patent is directed to a method of making a material that can absorb fluids. The method involves using a cement material that contains a substance called an absorbing material. The cement material is hydrated to form a material that contains the absorbing material and the fluid. The absorbing material retains the fluid after the cement material is hydrated. This material can be used to make concrete with the absorbing material dispersed throughout it. The absorbing material is more absorbent than the aggregate material used in the concrete. The technical effect of this is that the material made using this method has the ability to absorb fluids, making it useful in a variety of applications where fluid absorption is important.

Problems solved by technology

These locations may experience erosion such as, for example, the erosion of soil and erosion that affects the integrity of structural substructures.
However, the copolymers of the cementitious material of the '271 patent application apparently absorb significant water only during hydration.
Therefore, the '271 patent application does not disclose a material that may absorb and re-absorb liquid such as, for example, water during conditions such as flooding.
Therefore, the copolymers included in the cementitious materials disclosed in the '271 patent application do not provide additional protection for mitigating erosion at a location subject to flooding.

Embodiment Construction

[0014]FIG. 1 illustrates an exemplary hygroscopic material 10. Hygroscopic material 10 may be a cementitious composition. For example, hygroscopic material 10 may be concrete. It is also contemplated that hygroscopic material 10 may be any other suitable composition for use in structural applications such as, for example, a mortar composition. Hygroscopic material 10 may include an absorbing material 15.

[0015]Hygroscopic material 10 may be mixed material. Hygroscopic material 10 may also be a non-mixing material that may be laid out dry during construction. Hygroscopic material 10 may be placed in any suitable method such as, for example, in a single layer 20 or in multiple layers 20 as illustrated in FIG. 1. Hygroscopic material 10 may be a mixed cementitious material such as, for example, mixed concrete. Hygroscopic material 10 may also be a non-mixing cementitious material such as, for example, non-mixing concrete. Hygroscopic material 10 may be a dry material. Hygroscopic materi...

Abstract

A method is disclosed. The method includes providing a cementitious material, the cementitious material including an absorbing material. The method also includes absorbing a fluid into the absorbing material during hydration of the cementitious material. The method further includes retaining the fluid in the absorbing material after hydration of the cementitious material.

Description

TECHNICAL FIELD[0001]The present disclosure is directed to a material composition and, more particularly, to a hygroscopic cementitious material.BACKGROUND[0002]Cementitious materials such as, for example, concrete are used in a wide variety of building applications. Cementitious materials may be used in applications involving contact with running or rising water such as, for example, locations on or near coastlines or areas subject to flooding. These locations may experience erosion such as, for example, the erosion of soil and erosion that affects the integrity of structural substructures.[0003]One patent application that describes cementitious materials that may be used in applications involving fluid such as flooding water is U.S. Patent Application No. 2013 / 0098271 (the '271 patent application) to Eberwein et al., published on Apr. 25, 2013. The '271 patent application discloses dry mortar mixtures including copolymers that absorb water during hydration to optimize water-cement...
