Screed

As a characterization of speech/writing

The most common use of screed is roughly synonymous with diatribe.

As a tool

Screed is a flat board, or a purpose-made aluminium tool, used to smooth concrete after it has been placed on a surface. Also used to assist in leveling the application of plaster.[1]

In the UK, screed has also come to describe a thin, top layer of material (traditionally sand and cement), poured in site on top of the structural concrete or insulation, on top of which other finishing materials can be applied, or it can be left bare to achieve a raw effect. It is becoming more common to use "self leveling" poured screeds which use materials other than cement as their binder. A recent development in the UK is the delivery, mixing, and pumping of screed from a single vehicle. Where previously screed jobs required a separate pump to administer the screed, these new machines can now administer the screed directly from the mixing pan to the floor at a range of up to 60 meters.

In the US screeding is the process of cutting off excess wet concrete to bring the top surface of a slab to the proper grade and smoothness.
