METHODS AND SYSTEMS FOR HANDLING CONCRETE MIXER TRUCK HAVING RETURN CONCRETE
There is described a computer-implemented method for handling a mixer truck containing a return concrete load. The method generally has: accessing return concrete data including at least quantity data indicative of a quantity of the return concrete load contained in the drum of the mixer truck and composition data indicative of a composition of the return concrete load contained in the drum; accessing ticket data including job tickets each including a ticket specification; establishing a list of eligible job tickets by comparing the return concrete data to each job ticket, and including a given one of the job tickets in the list contingent upon finding a match between the ticket specification and the return concrete data; and generating a signal indicative of the established list of eligible job tickets.
Correlating energy to mix cement slurry under different mixing conditions
One example of correlating energy to mix well cement slurry under laboratory conditions to field conditions can be implemented as a method to determine energy to mix cement slurry. Electrical power supplied to an electric mixer in mixing a specified well cement slurry is measured. An energy to mix the specified well cement slurry is determined from the measuring. The determined energy to mix the specified well cement slurry and specifications of field equipment for use in mixing the specified well cement slurry at a well site are compared. The field equipment is a different configuration than the electric mixer. Based on the comparing, it is determined whether the well cement slurry needs redesigning according to capabilities of the field equipment.
Method For Adjusting Concrete Rheology Based Upon Nominal Dose-Response Profile
The invention relates to a method for adjusting concrete rheology requiring only that load size and target rheology value be selected initially rather than requiring inputs into and consultation of a lookup table of parameters such as water and hydration levels, mix components, temperature, humidity, aggregate components, and others. Dosage of particular rheology-modifying agent or combination of rheology-modifying agents is calculated based on a percentage of a nominal dose calculated with reference to a nominal dose response (NDR) curve or profile. The NDR profile is based on a correlation between a rheology value (e.g., slump, slump flow, yield stress) and the rheology-modifying agent(s) dose required to change rheology value by one unit (e.g., slump change from 2 to 3 inches) such that exemplary methods can employ corrective dosing based on the NDR and the measured deviation by the system.
ANALYZING MIXABILITY OF WELL CEMENT SLURRIES
Some aspects of what is described here relate to analyzing a well cement slurry. In some aspects, a well cement slurry is mixed in a mixer under a plurality of conditions. The plurality of conditions correspond to a plurality of distinct Reynolds number values for the well cement slurry in the mixer. Power number values associated with mixing the well cement slurry in the mixer under the plurality of conditions are identified. Each power number value is based on an amount of energy used to mix the well cement slurry under a respective one of the plurality of conditions. Values for parameters of a functional relationship between power number and Reynolds number are identified based on the power number values and the Reynolds number values for the plurality of conditions.

Mortar Delivery System
A Mortar Delivery System is described. The Mortar Delivery System provides precise control of the delivery and application of mortar in addition to the mixing and tempering of mortar. Such control eliminates the use of a hand trowel in brick, block and stone laying applications. Sensing and control are integrated with the Mortar Delivery System to make it an important element of a robotic brick laying system. The Mortar Delivery System contains sensors to measure mortar viscosity and workability, mortar flow rate, and mortar nozzle pressure. The data from the Mortar Delivery System sensors can be used to change the rotational speed of the shear blades, change the amount of water being used for mixing or tempering, and change the delivery speed of the mortar. Such changes result in precise control of mortar that is in turn suitable for automated or semi-automated building processes.
