Solidia Technologies | Date: 2014-12-29

The invention provides novel methods for anticorrosive protection of iron or steel surfaces, such as on embedded iron or steel reinforcement components in composite materials and on steel surfaces of piles and vessels. The unique siderite coating formed during a carbonation curing possesses excellent anticorrosive properties and is suitable for improving the overall service life of coated objects.


The invention encompasses equipment used to condition a recirculating gas stream in order to cure a CO_(2 )Composite Material (CCM) and processes that use such equipment to cure the CCM. The gas conditioning equipment allows for a process that controls, reduces or eliminates the rate-limiting steps associated with water removal during the curing of a composite material. The equipment may include, but will not be limited to, control over the temperature, relative humidity, flow rate, pressure, and carbon dioxide concentration within the system; which includes the conditioning equipment, any vessel containing the CCM, and the material itself. Flow rate control can be used as a means to achieve uniformity in both gas velocity and composition.

The invention provides novel marble-like composite materials and methods for preparation thereof. The marble-like composite materials can be readily produced from widely available, low cost raw materials by a process suitable for large-scale production. The precursor materials include calcium silicate and calcium carbonate rich materials, for example, wollastonite and limestone. Various additives can be used to fine-tune the physical appearance and mechanical properties of the composite material, such as pigments (e.g., black iron oxide, cobalt oxide and chromium oxide) and minerals (e.g., quartz, mica and feldspar). These marble-like composite materials exhibit veins, swirls and/or waves unique to marble as well as display compressive strength, flexural strength and water absorption similar to that of marble.

The invention provides novel slate-like composite materials and methods for preparation thereof. The slate-like composite materials can be readily produced from widely available, low cost precursor materials by a process suitable for large-scale production. The precursor materials include calcium silicate, for example, wollastonite, and particulate filler materials which comprise silicon dioxide-rich materials such as quartz, mica, feldspar, sand and glass. Additives can include calcium carbonate-rich and magnesium carbonate-rich materials. Various additives can be used to fine-tune the physical appearance and mechanical properties of the composite material, such as colorants such as particles of colored materials, such as colored glass, colored sand, and colored quartz particles, and pigments (e.g., black iron oxide, cobalt oxide and chromium oxide). These slate-like composite materials exhibit visual patterns unique to slate as well as display compressive strength, flexural strength and water absorption similar to that of slate.


The invention provides compositions and methods for controlling setting of carbonatable calcium silicate compositions that are contaminated with hydrating materials. These carbonatable calcium silicate cements are suitable for use as non-hydraulic cement that hardens by a carbonation process and may be applied in a variety of concrete components in the infrastructure, construction, pavement and landscaping industries.


Apparatus and methods for curing composite compositions that react with CO_(2). The apparatus in general includes an easily transportable and easily assembled curing structure, such as a plastic sheet housing supported by gas pressure and/or by mechanical supports. Apparatus for providing reagent CO_(2), for measuring water content and for removing water, and for controlling temperature, flow rates and flow directions through the curing structure. Examples of curing procedures and examples of cured materials in desired shapes are described.
