    摘要: The invention discloses a method for predicting the solubility of at least one species at a specified pH value in an aqueous buffer comprising at least one weak acid species and/or at least one weak base species. The method comprises the steps of: a) selecting a start composition of the buffer, giving a start value for the total solute concentration; b) calculating the concentrations of all ionic species present in the buffer at the specified pH value from the total composition of the buffer and available dissociation constants; c) calculating the solubility limits of each combination of ionic species present in the buffer from available solubility products, taking the concentrations calculated in step a) into account; d) comparing the concentrations of all ionic species calculated in step a) with the solubility limits calculated in step b) and determining if any solubility limit is exceeded; e) if no solubility limit is exceeded, increasing the total solute concentration of the buffer or, if at least one solubility limit is exceeded, decreasing the total solute concentration of the buffer, and; f) repeating steps b)-e) until a predetermined convergence criteria is met.

    摘要: The present invention generally relates to mixing systems for concrete, mortar, grout or other aggregate and more specifically to portable single person carries mixing systems capable of mixing concrete or other aggregates uniformly, rapidly and with less waste. In accordance with one aspect of at least one embodiment of the present disclosure, a portable aggregate mixing system is disclosed comprising a mixer with a power source and mixing tines and a mixing container comprising sidewalls, a bottom surface, a front and back wall and an open top. The mixing system coordinates the mating of the mixing blades or tines of a mixer with the surface characteristics of a customized or standard mixing tub or wheelbarrow to ensure uniform mixing of aggregate occurs quickly with minimal waste.
