A system and process for producing a variety of dry mix construction and ancillary construction materials (DMC) with improved structural properties. The system and process employs a material classification unit (204) that classifies at least one of plurality of raw materials (A, B, . . . N) based on their particle size and physical properties. These classified raw materials are stored separately in material handling compartments (260) and are selected according to the construction grade requirements of the end user. The invention further involves the use of a material selection unit (210) which controls the functioning of various components of present invention. The system and process also provides reutilization of industrial waste products like fly ash, blast furnace slag to produce a variety of construction and ancillary construction materials.

This invention encompasses rubber modified asphalt cement compositions, as well as systems, apparatuses, methods for preparing, as well as methods for using rubber-modified asphalt cement compositions.

The disclosure provides a method and a system for processing concrete granulate for subsequent recycling of the concrete granulate. In the method, a container of the system is filled with concrete granulate, said container being gas-tight at least in some regions. Subsequently, gas comprising CO2 is fed, continuously or noncontinously, according to a level of CO2 absorption by the concrete granulate in the container, said level being determined by means of at least one sensor. After a predefined CO2 saturation of the concrete granulate has been detected, the concrete granulate, which have been enriched with CO2, are removed.

A portable skid-mounted concrete production system includes individual units for the production of concrete that are each mounted on a portable skid, which may be individually transported on cargo trucks to construction sites for on-site concrete production. The skids can be offloaded at a construction site and then supply lines for inputting various ingredients into the concrete mix may be connected between the skid units, as well as electrical power lines for providing power to equipment within the system. The system may be set up on-site to begin continuous production of concrete within hours of offloading the skids.

An apparatus for delivering a wet concrete mix to a product mold, where the apparatus comprises a hopper configured to retain a fresh concrete mix, a source of treated water having a concentration of nanobubbles of a gas at least double a natural concentration of nanobubbles of the gas within a natural state of the water, a water transport coupling the source of treated water with the hopper, a valve interposed within the water transport for selectively releasing the treated water into the hopper, and a mixer in communication with the hopper for mixing the treated water with the fresh concrete mix to yield an infused wet concrete.

A nanobubble-infused liquid is mixed into a dry concrete mix to form an infused wet concrete, where the nanobubble-infused liquid includes a concentration of nanobubbles of a gas at least double a natural concentration of nanobubbles of the gas within a natural state of the liquid. The nanobubble-infused liquid is preferably liquid water infused with a desired concentration of carbon-dioxide (CO.sub.2) nanobubbles sized within a certain prescribed range. The infused wet concrete is then transported to the mold of a concrete products forming machine to form a molded product that has enhanced qualities including increased carbon capture within the resulting concrete product, improved curing times, increased flowability, self-healing, and improved release from the product mold.

A method and plant for cooling a mixture of concrete, includes: loading in a hermetically sealed tank a given quantity of ingredients to form the concrete, the ingredients including a predetermined quantity of water; regulating the pressure in the tank to obtain a transitory degree of vacuum in the tank; regulating the pressure inside a hermetically sealed condensation chamber to obtain a basic degree of vacuum in the condensation chamber that is greater than the transitory degree of vacuum, such that the pressure in the condensation chamber is lower than the pressure in the tank; operatively connecting the tank and the condensation chamber to substantially equalize the internal pressure in the tank and in the condensation chamber to a resulting degree of vacuum and to cause at least partial evaporation of the water from the tank towards the condensation chamber to lower the temperature of the ingredients in the tank.

Described is a cementitious material delivery system having at least one material box (10) with a lower access point (16) that is connected to a collection hopper (22). Also described is a cementitious material delivery system having at least one container (38) with an unloading end (42) that is located proximate to a collection hopper (22). The at least one container (38) can be positioned on at least one shelf (18) that can be raised so that the unloading end (42) is tilted toward the collection hopper (22).

an integrated mixer and nozzle device for a 3D printer of building construction components includes: a support; a mixer disposed inside the support to mix a first material and a second material together to produce a flowable mixture; a conveyor directly connected to the mixer to convey the flowable mixture in a first direction; and a nozzle directly connected to the conveyor to extrude the flowable mixture and to discharge the extruded mixture in a second direction different from the first direction.
