APPARATUSES AND SYSTEMS FOR AND METHODS OF GENERATING AND PLACING ZERO-SLUMP-PUMPABLE CONCRETE
According to one or more embodiments of the present invention, modification of concrete within a pumping line is achieved with new designs of inline static mixers allowing passage of concrete material that is primarily of solids in the form of suspended minerals, cement and aggregates, and without benefit of the flow of additional fluid, such as the airflow driving a shotcrete process. According to one or more embodiments of the present invention, modification within a concrete pumping line is essential where unmodified concrete is necessary for purposes of batching or pumping, such as where the modification creates a very rapid set or an extreme thickening. According to one or more embodiments of the present invention, modification, unmodified concrete can be delivered to the point of inline modification at the end of a pumping line, where highly reactive components can then be intermixed. According to one or more embodiments of the present invention, this allows volume production of Roman Concrete or a hot mortar activated with quicklime, facilitates the inclusion of highly reactive shrinkage compensating agents, makes the use of alkali-activated or geopolymer concrete more practical for large-scale production, and makes possible very rapid additive-manufacturing methods with low-cost conventional delivered concrete.
