Abstract
Hydraulic cement compositions that include a carbonate compound composition, e.g., a salt-water derived carbonate compound composition containing crystalline and/or amorphous carbonate compounds, are provided. Also provided are methods of making and using the hydraulic cements, as well as settable compositions, such as concretes and mortars, prepared therefrom. The cements and compositions produced therefrom find use in a variety of applications, including use in a variety of building materials and building applications.
Claims35
A hydraulic cement comprising a carbonate compound composition precipitated from an alkaline-earth-metal-containing water.
A settable composition comprising:
- a hydraulic cement comprising a carbonate compound composition precipitated from an alkaline-earth-metal-containing water;
- aggregate;
- and
- water.
A method of making a cement, said method comprising:
- subjecting a volume of an alkaline-earth-metal-containing water to carbonate compound precipitation conditions to produce a precipitated carbonate compound composition and a mother liquor;
- and
- separating said precipitated carbonate compound composition from said mother liquor to produce said cement.
A method comprising:
- combining a hydraulic cement comprising a carbonate compound composition precipitated from an alkaline-earth-metal-containing water cement with water to produce a hydrated cement composition;
- and
- allowing said hydrated cement composition to set into a solid product.
A system for producing a hydraulic cement, said system comprising:
- an input for an alkaline-earth-metal-containing water;
- and
- a carbonate compound precipitation station that subjects said water to carbonate compound precipitation conditions and produces a precipitated carbonate compound composition.
