Cement composition and classification. A slurry of Portland cement in water is used in wells because it can be pumped easily and hardens readily, even under water. It is called Portland cement because its inventor, Joseph Aspdin, thought the solidified cement resembled stone quarried on the Isle of Portland off the coast of England.

Diaphragm Materials Design. The materials used in the manufacture of flush diaphragms vary with the type of sensor technology and the intended liquid media to be measured. Dry cell sensing elements have typically have thicker and more robust diaphragms which can be used with more abrasive media such as concrete and slurries.

Like precast concrete, on site concrete is formed in a mold and then lifted in place. However, one of its advantages over precast slabs is that it does not need to be moved far to be lifted into place. For a building that requires large, unwieldy and custom concrete molds, onsite is usually the way to go.

Nov 06, 2015Plug valves solve downtime problems where ball valves failed at paper mill. When the plant goes down for outage the white liquor cools and hardens up almost like concrete. When this happens the only thing the mill can do is to try inline high pressure flushing of the valves. Removing every single ball valve, disassembling, replacing seats,

Once the excavated depth is reached, the reinforcing steel cage is lowered into the panel and the slurry is displaced with concrete placed through a tremie pipe from the bottom up. The concrete is allowed to set, forming the diaphragm wall. For excavations in harder materials or rock, Hydraulic Cutters are used in place of the clam shell buckets.

All of the problems associated with moisture vapor movement in a concrete slab will go away in time as the slab dries, as long as there is no source of additional water into the slab. Since the most common source is moisture in the ground beneath the slab, the solution is to completely take the ground out of the equation, by sealing the bottom of the slab.
