Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for characterization of aggregate particles. A method includes obtaining, from a set of low fidelity sensors, first sensor data of a first portion of particles; obtaining, from a set of high fidelity sensors, second sensor data of the first portion of particles, the second sensor data comprising a higher fidelity representation of characteristics of the first portion of particles than the first sensor data; training a characterization model using the first sensor data and the second sensor data, the training comprising: providing, as training data to the characterization model, the second sensor data; and processing the second sensor data with the characterization model to correlate the first sensor data with the second sensor data. The first sensor data can indicate shape characteristics of each particle; and the second sensor data indicates a surface area of each particle.

Abstract: Methods, systems, and apparatus for developing recipes for concrete mixtures are disclosed. A method includes obtaining second input data including a second recipe for combining the plurality of ingredients; mixing the plurality of ingredients according to the second recipe to produce a second mixture; obtaining sensor data representing one or more qualities of the second mixture; evaluating the second mixture using the sensor data to obtain performance measures of the concrete mixture; processing the input data with the mixture prediction model to obtain a corresponding output of the mixture prediction model, the corresponding output including predicted performance measures for the second mixture; and adjusting parameters of the mixture prediction model based on comparing the output of the mixture prediction model to the performance measures of the second mixture.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for processing recycled concrete aggregate (RCA). A method includes obtaining an aqueous carbonate solution by exposing an aqueous alkaline solution to a carbon dioxide laden fluid; performing a treatment process on a first portion of RCA particles using a first set of parameters, the treatment process including exposing the first portion of RCA particles to the aqueous carbonate solution; after performing the treatment process, obtaining measurements of the first portion of RCA particles; determining, using the measurements of the first portion of RCA particles, a second set of parameters; and performing the treatment process on a second portion of RCA particles using the second set of parameters. Exposing the first portion of RCA particles to the aqueous carbonate solution includes soaking the first portion of RCA particles in the aqueous carbonate solution.
