Abstract: Colored polymeric sand that is made by mixing a pigment onto sand to form colored sand, applying an acrylate-based polymeric coating on the colored sand, drying the acrylate-based polymeric coating, and applying a second polymeric material on the dried acrylate-based polymeric coating. The second polymeric material can have an ingredient (e.g., coating) that is water soluble. The resulting colored sand product can be used, for example, between pavers.

Abstract: A sprayer apparatus for applying treatment liquid to a landscaping material. The sprayer apparatus includes first and second spray outlets and an agitator therebetween. In use, the landscape material to be treated is first sprayed, the material is agitated (e.g., turned), and a second spray of treatment liquid is applied to the landscape material. Also described are methods for applying a treatment, such as colorant, to an installed landscaping material (such as wood chips or mulch), reducing the need to replace worn or weathered material. The methods include applying a pre-treatment to protect elements proximate the landscape material that are not to be treated, applying a treatment liquid to the landscaping material by spraying, and then rinsing any elements proximate the landscape material that may have be inadvertently and undesirably treated.

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.

Abstract: A method for solidifying cementitious wastewater by combining the wastewater with a super absorbent polymer composition that includes a UV-stabilizer to form a mixture and disposing of the mixture as solid construction waste. The UV-stabilizer may be a stabilizing additive in the super absorbent polymer composition that inhibits the reversion from a solid or semi-solid mixture back to a liquid. In some embodiments, the method includes placing the mixture in UV-light non-transmissive packaging. After placing the mixture in the UV-light non-transmissive packaging, the package is closed and can be permanently sealed. The sealed package with solidified material therein can then be disposed as solid construction waste. The super absorbent polymer composition can include zeolite or other molecular sieves.

Abstract: An improved dry mix dispensing apparatus and method for controllably dispensing materials from bulk storage bags are disclosed. A support structure is provided for elevating loaded bulk bags over a collector and discharge means that controllably empties the contents of the bag, one batch at a time, as needed, into an underlying batch mixer. The collector only processes that material currently being dispensed, and the bag continues to store the bulk material until actually dispensed through the collector. The dispensing apparatus is rapidly collapsible in the vertical and lateral directions for ease of transport and movement about the construction site.

Abstract: An improved silo and delivery system for efficiently handling dry mortar-blend compositions at construction sites is disclosed. Mortar-blend compositions are premixed to desired specifications and packaged at remote mixing stations into large bag containers that are transported to the construction site. A silo designed for uniquely servicing batch mixers is provided at the construction site for storing the premixed composition. The bag contents are emptied into the silo and are sealed therein against exposure to environmental elements. The silo contents are discharged by means of simple gravity flow on a batch-need basis into a batch mixer operatively underlying the silo.
