  • Patent number: 10494304
    Abstract: A calcium silicate insulation product includes a calcium silicate hydrate matrix that is predominantly but not substantially all xonotlite, for example 51-90 weight percent xonotlite and 10-49 weight percent tobermorite. The insulation product also contains wollastonite, and may include fines of lime and silica and reinforcing carbon fibers. A method of producing the insulation product includes providing the components of the insulation as dry solids, blending the dry solids with water to form a slurry, filter pressing the slurry to form a pressed shape, and curing the pressed shape under steam pressure only until the desired proportions of xonotlite and tobermorite are achieved in the calcium silicate hydrate matrix.

  • Patent number: 9409819
    Abstract: A water repellent sand mixture includes at least water repellent sand and cement at a weight ratio of 2% or more and 5% or less relative to the water repellent sand. The mixture achieves condensation between the water repellent sand particles by the hydration reaction of the cement, which improves dynamic stability. The mixture can be kept in a block shape due to such improved dynamic stability, water repellency, and less slidable surfaces of the sand particles.

    Abstract: A simple and easily useable system for reverting an uncured colored concrete material back to a gray color, by merely determining the original pigment and loading initially used to color the concrete material. The system utilizes a collection of pigment mixtures that can be selected and combined as needed to revert virtually any colored concrete back to a gray color, thus eliminating or reducing the expulsion of non-gray or colored concrete and/or dirty rinse water. Additionally, the volume of rinse water needed to clean out gray concrete is significantly less than that needed to clean out colored concrete.

  • Publication number: 20130008346
    Abstract: Complex inorganic titanate pigments with low dopant levels (i.e., less than about 5%) exhibit coloristic and enhanced infrared (IR) reflectance characteristics that make them useful in formulating colors exhibiting high IR reflectivity. This characteristic is becoming increasingly useful as a way to keep exterior surfaces and articles cooler during exposure to direct sunlight. Achieving this can decrease energy (e.g., cooling/air conditioning) consumption and costs. Low-loaded titanates can boost IR reflectivity by 1 to 10% in selected visual color spaces. Paint compositions containing those low loaded titanate pigments and a method for providing a surface with high infrared reflectance utilizing those pigments are also disclosed.

  • Patent number: 8057593
    Abstract: The present invention relates to a pigment dispersion and a black water-reducing agent, more particularly, to a pigment dispersion comprising a carbon black whose surface is modified with an aminosilane compound and a polycarboxylic acid-based water-reducing agent, and a black water-reducing agent using the same. The present invention is characterized in that the surface-modified carbon black with an aminosilane compound is water-dispersed by using a polycarboxylic acid-based water-reducing agent as a dispersing agent having better performance than a naphthanlene-based water-reducing agent. Therefore, the present invention can display black color of the water-reducing agent and cement at the same time and improve the flowability of cement owing to the presence of carbon black in the form of nanoparticles, which enables to manufacture ultrahigh strength concrete.

  • Publication number: 20090272297
    Abstract: IR reflective cementitious systems comprising one or more IR reflective pigments are provided. The cementitious systems of the invention may be in the form of mixtures which increase the total solar reflectivity (TSR or albedo) and the Solar Reflectance Index (SRI) of concrete are provided. The cementitious systems are infrared reflective and may be toppings mixed with water for application to existing concrete surfaces, or dry-shake hardeners for application to freshly-placed plastic concrete. The formulations of the invention utilize one or more of cementitious binder(s), graded aggregates, super-plasticizers, one or more pigments selected for improving infrared reflectivity and color composition, and/or optionally other additives, such as dry redispersible polymers or fillers to provide decorative and LEED compliant, highly durable (sustainable) concrete hardscapes and other decorative concrete.

  • Patent number: 7556683
    Abstract: The photocatalytic granular mixture for mortar and concrete includes a photocatalyst in the form of at least two granular classes with different B.E.T. specific surfaces. It has a photocatalytic activity greater than that of a monodisperse photocatalyst with a single range of B.E.T. specific surface, and thus permits, in association with a conventional hydraulic binder, to obtain construction and repair materials whose aptitude for self cleaning, for the reduction of odors, and for the depollution of ambient air, is considerably improved.

  • Publication number: 20090139435
    Abstract: The present invention provides acidic compositions and methods that are adapted to impart color to cementitious or mineral substrate surfaces. Specifically, the present invention relates to acidic compositions and methods adapted to treat cementitious or mineral substrate surfaces that have the advantage of using a less corrosive acid-based solution. The acidic composition incorporates species including a weak base in equilibrium with a conjugate acid. The presence of such species moderates the corrosive behavior of the acid while still allowing excellent coloring action to occur.

  • Patent number: 7497904
    Abstract: A cementitious composition is provided that is composed of hydraulic cement and a liquid coloring suspension. The liquid coloring suspension which contains polycarboxylate dispersant and pigment provides the cementitious composition with increased dispersion of pigment particles, lowered water content, and improved coloration over that observed in the prior art. Also, a liquid coloring suspension for cementitious compositions is provided which contains polycarboxylate dispersant, pigment, and thixotropic additive. The liquid coloring suspension increases the color of cementitious compositions, reduces the water content and has long term stability in that it does not become increasingly viscous over time.
