Google patents system to calculate exact concrete paste needs

Patent drawing from the official filing.

The filing describes a method for measuring individual particles in a concrete mix to determine their specific shape irregularity. By calculating how much extra surface area these irregular shapes create compared to perfect spheres, the system determines the minimum amount of paste required to make the mixture workable. It then sends a signal to the mixing equipment to add exactly that amount of material.

Why it mattersThis could help construction sites reduce waste and ensure consistent concrete quality by automating the precise calculation of ingredient ratios based on real-time particle analysis.

In the filing’s own words

v i p ( I) s i p ( II) a i p ( III) v i s ( IV) s i s ( V) This disclosure involves a system, non-transitory computer readable medium, and a method for determining a minimum amount of paste to be added to a concrete mix. This includes measuring a plurality of n particles, and for each particle i determining: a particle volume (I), a particle surface area (II), a particle maximum dimension (III), a spherical volume (IV) and spherical surface area (V) associated with a sphere having a diameter equal to the particle maximum dimension (III), and a residual free surface S i. Then, for the plurality of particles, a shape irregularity factor η is determined based on the residual free surface S i and the particle volume (I) for all n particles. The shape irregularity factor is used to determine a minimum amount of paste for combination with the plurality of n particles to create a workable concrete mixture, and a control signal is sent to a concrete preparation system.

What exactly they claim (claim 1)

1. A method comprising: measuring a plurality of n particles, and for each particle i determining: a particle volume v i p; a particle surface area s i p; a particle maximum dimension a i p; a spherical volume v i s and spherical surface area s i s associated with a spine having a diameter equal to the particle maximum dimension a i p; and a residual free surface S i; determining, for the plurality of particles, a shape irregularity factor η based on the residual free surface S i and the particle volume v i p for all n particles; determining, from the shape irregularity factor η, a minimum amount of paste for combination with the plurality of n particles to create a workable concrete mixture; and sending a control signal to a concrete preparation system to cause the concrete preparation system to add at least the minimum amount of paste to a concrete mix comprising the plurality of n particles.
