Continuous method including: mixing water and cementitous powder to form slurry; mixing the slurry and reinforcement fibers in a single pass horizontal continuous mixer to form fiber-slurry mixture, the mixer including an elongated mixing chamber having a reinforcement fiber inlet port, and upstream of the fiber inlet port is an inlet port to introduce water and cementitous powder together as one stream or at least two inlet ports to introduce water and dry cementitous powder separately as separate streams into the chamber, a rotating horizontal shaft/s within the chamber, part of the chamber for mixing the fibers and slurry and moving the fiber-slurry mixture to a mixture outlet; discharging the fiber-slurry mixture from the mixer outlet; forming and setting the fiber-slurry mixture on a moving surface; cutting the set mixture into fiber reinforced concrete panels and removing the panels from the moving surface.

A method in which a stream of dry cementitious powder passes through a first conduit and aqueous medium stream passes through a second conduit to feed a slurry mixer to make cementitious slurry. The cementitious slurry passes through a third conduit and a reinforcement fiber stream passes through a fourth conduit to feed a fiber-slurry mixer which mixes the slurry and discrete fibers to make a stream of fiber-slurry mixture. An apparatus for performing the method is also disclosed.

A system and process for mixing and distributing building materials. This system and process can also include a way or a means or calibrating the mixing of these materials. This system and process can also include a system for tracking the materials that flow through the system, and for controlling the type of material used in the system.

A control system for a concrete plant adds intelligent capabilities in the concrete plant that may enhance safety, localize control of the concrete plant, and assist with troubleshooting. The control system may also enhance accuracy for determining an amount of mixed concrete dispensed, or amounts of concrete ingredients to dispense, and may eliminate the need for equipment used to verify the amount of mixed concrete or concrete ingredients dispensed.

The present disclosure involves systems and methods for applying CO2 to concrete, which may be performed in-situ or through a separate, stand-alone process. According to another embodiment disclosed herein, a system and method for applying CO2 to one or more materials used in the production of concrete is also provided.

A method for green-to-fired shrinkage control in honeycomb ceramic article manufacture, including: measuring, prior to mixing, the particle size distribution properties of at least one fine particle size graphite pore former ingredient of a provided ceramic source batch mixture; calculating the expected shrinkage of the green body to the fired ceramic article based on the measured particle size distribution properties of the at least one fine particle graphite pore former; making the honeycomb ceramic article; measuring the shrinkage of the resulting fired honeycomb ceramic article; and adjusting the ceramic source batch mixture in a subsequent batch material schedule, as defined herein, wherein the adjusted ceramic source batch mixture provides finished honeycomb ceramic articles having controlled green-to-fired shrinkage.

An apparatus including a first dispensing device configured to supply a first material to a conveyor belt of the main conveyor device in response to control by the computer processor, and a second dispensing device configured to supply a second material on top of the first material, while the first material is on the conveyor belt to form a combination comprised of at least the first and second materials, in response to control by the computer processor. The combination may be compressed by a first compression device in response to control by the computer processor. The compressed combination may be stirred by a first stirring device in response to control by the computer processor to form a first modified combination. The first modified combination may be compressed by a second compression device in response to control by the computer processor to form a compressed first modified combination.

The system for determining a status of a valve being mounted in a liquid supply line of a concrete mixer and being actuatable via an actuator generally has: an actuator accelerometer mounted to the actuator and being adapted to measure an actuator position associated with a position of the valve; a reference accelerometer mounted to the concrete mixer and being adapted to measure a reference position fixed relative to the concrete mixer, the actuator position and the reference position being measured while the concrete mixer is fixed relative to the ground; a computing device adapted to receive the actuator and reference positions, the computing device being adapted to determine the status of the valve based on the actuator position, the reference position and calibration position data; and to generate status of the valve indicative of the determined status of the valve.
