Method and system to convert demolished concrete into a readily recyclable product which is capable to reliably replace virgin feedstock that is used for manufacturing concrete, wherein converting the demolished concrete into the readily recyclable product comprises adding a plurality of information carriers to said product, wherein the plurality of information carriers are regularly distributed into said product by securing that each separate fraction of the product will hold a dedicated information carrier, and wherein each such dedicated information carrier is arranged to refer to information that is characteristic for the fraction of the product in which the dedicated information carrier is contained.

Methods of determining the integrity of a well are provided. The methods include mixing conductive materials into a fluid, introducing the fluid into the well, and allowing the conductive materials to coat a surface of a subsurface formation, thereby forming an electrically conductive data conduit coating. The methods further include transmitting data through the electrically conductive data conduit coating to determine the integrity of the well.

Concrete can be one of the most durable building materials and structures made of concrete can have a long service life. Consumption is projected to reach approximately 40 billion tons in 2017. Despite this the testing of concrete at all stages of its life cycle is still in its early stages although testing for corrosion is well established. Further many of the tests today are time consuming, expensive, and provide results only after it has been poured and set. Embodiments of the invention provide concrete suppliers, construction companies, regulators, architects, and others with rapid testing and performance data regarding the cure, performance, corrosion of concrete at different points in its life cycle based upon a simple electrical tests that remove subjectivity, allow for rapid assessment, are integrable to the construction process, and provided full life cycle assessment. Wireless sensors can be embedded from initial loading through post-cure into service life.

The invention relates to the use of a building composition marker comprising at least one alpha-amino acid, alpha-amino acid salt or a mixture thereof in a building composition. The invention also relates to a building composition comprising such a building composition marker, and to a process for producing the building composition. The invention further relates to a building composition marker comprising at least one alpha-amino acid, alpha-amino acid salt or mixture thereof, and one or more components selected from:vinyl ester homopolymers, vinyl ester copolymers comprising one or more vinyl ester units and one or more monomer units from the group selected from olefins, vinylaromatics, vinyl halides, acrylic esters, methacrylic esters, monoesters or diesters of fumaric and/or maleic acid, or silicon-functional monomers; (meth)acrylic ester homopolymers, (meth)acrylic ester copolymers comprising one or more (meth)acrylic ester units and one or more monomer units from the group of vinylaromatics, vinyl halides, monoesters or diesters of fumaric and/or maleic acid, or silicon-functional monomers; homopolymers or copolymers of dienes and also of olefins, diene copolymers comprising one or more diene units and one or more monomer units from the group selected from vinyl halides, (meth)acrylic esters, esters of fumaric or maleic acid, and vinylaromatics; homopolymers of vinylaromatics; homopolymers of vinyl halides; andpolysaccharides, polysaccharide ethers, and mixtures thereof.

Embodiments provide a method for monitoring structural integrity of a hardened cement. An aramide capsule, a cement, and a water to form a cement slurry. The cement slurry is set to form a hardened cement, where the aramide capsule is embedded in the hardened cement. Imperfections of the hardened cement are detected by measuring electrical resistivity of the hardened cement. The aramide capsule is formed by interfacial polymerization using a surfactant, a dispersed monomer, a crosslinker such that a semi-permeable membrane is formed surrounding a core.

A concrete curing blanket that includes a vapor barrier layer, a wicking layer, and pH-indicator, such as turmeric or Phenol Red incorporated into the concrete curing blanket. The pH-indicator may be a power or prills attached to the vapor barrier, the wicking layer, or another layer of the concrete curing blanket. Alternatively, the pH-indicator may be a series of ribbons or strips attached to the vapor barrier, the wicking layer, or another layer of the concrete curing blanket. As another alternative, the pH-indicator may be a matrix of discontinuous patches attached to the vapor barrier, the wicking layer, or another layer of the concrete curing blanket. As another alternative, the vapor barrier may include perforations.

A continuous ready mix joint or texture compound manufacturing system and a method for continuously manufacturing a ready mix joint or texture compound includes a continuous mixer having an inlet and an outlet, a pump disposed at the outlet of the continuous mixer, and a disperger having an inlet and an outlet. The continuous mixer is adapted to receive at least one dry ingredient and at least one wet ingredient at the inlet and continuously mix the at least one dry ingredient and the at least one wet ingredient to form a mixed composition. The pump is adapted to pump the mixed composition from the outlet of the continuous mixer to the inlet of the disperger. The disperger is adapted to receive the mixed composition and apply a shear force to the mixed composition to form a homogenized, disperged composition.
