Abstract: A sensor device includes a housing having a hole allowing substances to pass from an exterior of the housing to an interior of the housing, and a printed circuit board having a humidity sensor and at least one electronic component. The sensor device also includes a tube comprising a waterproof material, wherein a first end of the tube surrounds the humidity sensor, wherein a first seal is formed by between the first end of the tube and the printed circuit board, wherein a second end of the tube is located proximate the hole. The sensor device also includes a waterproof, breathable material layer disposed between the second end of the tube and the hole, wherein a second seal is formed between the material layer and the housing, wherein a third seal is formed between the material layer and the second end of the tube. The hole and the material layer allow water vapor to pass from the exterior to the humidity sensor.

Abstract: A plurality of sensing devices are inserted into a concrete mixture to be used at a construction site. The concrete mixture is poured to form one or more structural elements, wherein one or more sensing devices are embedded in the concrete of each structural element. Data relating to a first characteristic of the concrete in each structural element is received from the sensing devices. For each structural element, a second characteristic of the concrete of the associated structural element is determined, based on the first characteristic. A map showing the one or more structural elements is generated. For each of the one or more structural elements, a respective graphical indicator indicating the second characteristic associated with the respective structural element is displayed on the map. The map is displayed on a user device.

Abstract: First cost information relating to a first cost of production of a first concrete mixture, and second cost information relating to a second cost of production of a second concrete mixture, are received from a plurality of production facilities that produce concrete mixtures. First quality information relating to a first concrete mixture is received from a first construction site. Second quality information relating to the second concrete mixture is received from a second construction site. A map displaying a region containing the first construction site and the second construction site is displayed on a display device. The first cost information and the first quality information are presented in a graphical format and are overlaid over the map proximate the first construction site, and the second cost information and the second quality information are overlaid over the map proximate the second construction site.

Abstract: A system includes a memory, and a processor that obtains, for each of a plurality of batches of concrete produced at a first production facility, each batch produced in accordance with a formulation, data indicating a difference between a first quantity of a component specified in the formulation and a second quantity of the component actually used to produce the batch. The processor determines a first percentage value representing a percentage of the batches for which the difference is less than a predetermined limit, compares the first percentage value to second percentage values associated with second production facilities, determines a ranking value for the first production facility based on the comparing, and causes a display device to display the data, the percentage value, and the ranking value. The data may be displayed in the form of a table, a chart, and/or one or more graphical indicators.

Abstract: A system includes a memory adapted to store data and a processor. The processor receives, from a plurality of production facilities that produce concrete mixtures, first information relating to production of the concrete mixtures at the production facilities, receives, from a plurality of sites where the concrete mixtures are used, second information relating to use and performance of the concrete mixtures, stores the first and second information in the memory, generates third information based on a comparison of a first item selected from the first and second information with a second item selected from the first and second information, receives, from a processing device, a request for one of the first, second, and third information, and causes the processing device to display, the requested information and a map, such that portions of the requested information relating to respective geographical locations are overlaid over the respective geographical locations on of the map.

Abstract: An identifier of a batch of a product is received from a user device. A production facility at which the batch was produced is identified, from among a plurality of production facilities, based on the identifier. First information related to production of the batch at the production facility is retrieved from a memory. The user device is caused to display the first information.

The second information is received from the user device and stored in the memory.

Abstract: An identifier of a first production facility is received. Information related a plurality of production facilities that includes the first production facility is retrieved from a memory. A device is caused to display a first indicator indicating a percentage of batches of concrete produced at the first production facility in which a first quantity of a selected component is within a specified tolerance. A selected color is caused to appear in at least a portion of the first indicator, the selected color being selected based on the percentage. The device is caused to display, proximate the first indicator, a second indicator identifying a second production facility having a highest percentage of batches produced in which a second quantity of the selected component is within the specified tolerance, among the plurality of production facilities.

Abstract: A plurality of first formulas, each specifying first components used to produce a first concrete mixture, and first attributes of the first concrete mixture, is stored in a first memory. An order for a second concrete mixture is received, by a second processor, the order comprising a second formula of the second concrete mixture. The order is transmitted, by the second processor to the first processor. A determination is made, by the first processor, that the second formula is not included in the plurality of first formulas. The second formula is stored temporarily in a second memory. The second formula is transmitted, by the first processor, to a selected production facility. The selected production facility produces a batch of the second concrete mixture.
