Today, concrete is the most widely used human-made material (measured by tonnage).

the perfect passive participle of "concrescere", from "con-" (together) and "crescere" (to grow).

The 4C-Rheometer can be used in the process of mix design development as the primary tool for measuring the rheology of the test mixtures.

With information about the yield stress and plastic viscosity it becomes easier to differentiate between different SCC mixtures, thus making it possible to develop mixtures with rheological parameters targeted at particular types of castings e.g. As an example, the 4C-Rheometer was used for acceptance testing at a full-scale highway bridge deck casting in October 2006, where it proved a valuable tool in testing the concrete rheology onsite in order to avoid dynamic segregation, to control the moving front of the concrete, and to assure that the concrete could be finished with a slope of 3%.

They built kilns to supply mortar for the construction of rubble-wall houses, concrete floors, and underground waterproof cisterns.Rebar may become corroded, and concrete will crack.

As the rising phase reaches its peak, voltage-gated Na channels are inactivated whereas voltage-gated K channels are activated, resulting in a net outward movement of K ions, which repolarizes the membrane potential towards the resting membrane potential.… continue reading »
