Abstract: Pile splice assemblies, pile systems involving such assemblies and methods for splicing piles are provided. In this regard, a representative method includes: using strand locking devices to attach first and second anchors to respective strands of first and second piles; and securing the first and second anchors to each other.

Abstract: A method of mixing particulate cement and water in a primary mixing vessel to form a slurry batch, includes introducing a measured quantity of water into the vessel, introducing a measured quantity of particulate cement into the vessel, agitating the water and cement in the vessel to form a slurry, and while continuing such agitating, pumping slurry from the lower interior extend of the vessel and delivering the pumped slurry to the upper interior of the vessel, at high velocity, removing slurry from the vessel for flow to an auxiliary mixing vessel for mixing with aggregate, and employing wash water to wash remanent slurry from surfaces in the primary mixing vessel for flow to the auxiliary vessel.

Abstract: A method for forming foam, useful in mixing with concrete at a batching plant, includes the steps:a) supplying a synthetic resinous foaming agent, in liquid form,b) combining the foaming agent with water, to form a liquid mix, and pressurizing the mix,c) adding pressurized air to the mix,d) sub-dividing the mix into droplets, in a confined flowing stream,e) reducing the stream confinement,f) whereby the droplets expand as a foam.
