摘要:
Some implementations herein described improvements to concrete products and processes for producing concrete products that may provide a positive environmental impact and that can be stronger relative to the percent of cement used. Particular examples include improvements to zero-slump to near-zero-slump concrete mixture design, material storage and handling, batching, mixing, sequencing and curing processes, as well as forming and curing techniques.

A chute turning restriction mechanism includes: a rotary shaft on which a chute is disposed and which is provided to be capable of rotating relative to a vehicle body of a mixer truck; a bracket that is provided on the vehicle body and includes an insertion hole into which the rotary shaft is inserted and a cutaway portion formed by cutting away a part of the insertion hole; an inner diameter adjustment shaft provided across the cutaway portion to be capable of adjusting an inner diameter of the insertion hole, and configured to restrict rotation of the rotary shaft by reducing the inner diameter of the insertion hole; a rotary body that is provided to rotate together with the rotary shaft and includes an engagement groove; and a lock lever that is provided to be capable of rotating about the inner diameter adjustment shaft, and that restricts the rotation of the rotary shaft by engaging with the engagement groove.

System for transporting a load of cementitious slurry, which greatly extends the delivery time in which cementitious slurry may be delivered to a remote work site. The system comprises a trailer mounted tank having a pumping mechanism incorporated therein which continually circulates the cementitious slurry from one end of the tank to an opposing end during transport to the remote work site. The system extracts slurry from one end of the tank and reintroduces it at an opposing end of the tank. The pumping mechanism induces a turbulent flow in the slurry, which continually agitates the slurry, thereby preventing the settling of particles within the slurry. The system allows cementitious slurry to be commercially delivered at reasonable distances without significant fallout or degradation to the consistency of the slurry, and without impairment to the distribution equipment's ability to disperse the cementitious slurry at the remote work site.

摘要:
The present invention is a front discharge transit mixer apparatus. In one form of the present invention the operator has an environment surrounde by a large viewing area so as to increase his ability to control the vehicle. Further, creature comforts include increased head room in the cab, air conditing, heat, and storage compartments. A total weight system is provided for assisting in maintaining the proper weight distribution of the apparatus for passage over roads and bridges.

Disclosed is an apparatus for blending sand and solid additives selectively and at selected rates into water for injection into a well. The apparatus may be truck mounted, and includes a frame, an input line with manifold and pump, a mixing tank, a variable venturi nozzle for delivering water to the tank, and an output line with pump, manifold, and recycle line. An auger delivers sand to the mixing tank. Dry chemicals are fed to the tank adjacent the variable venturi nozzle where the water is turbulent, at low pressure, and in high shear. Liquid chemicals may also be pumped into the tank.

A plate-mounted assembly containing a suction connection, unloading hatches and level inspection windows, converts a cement mixer truck to a sand pumper truck.
摘要:
Container-agitator for transporting and mixing concrete slurry, consisting of a semicylindrical tank with horizontal axis. It has facilities for placing it on the chassis-cab of a truck as a standard container and for resting on the ground, and mechanisms for its loading on the truck or releasing on the ground, as well as for mixing the concrete contained therein. The legs on which it rests on the ground, allow the raising and releasing of the container from the truck, can be elongated and fixed at different heights and retracted for transportation, being driven by internal hydraulic means. The mixing of the slurry is provided by a rotatable shaft connected along the tank axis, having radial arms and shoes. For driving all mechanisms an internal combustion engine supplies the necessary power.
