ABSTRACT

These are the properties of plastic concrete that matter most in floors:

• workability; • finishability; • bleeding; • setting time; • plastic settlement.

This is the ease with which plastic concrete can be compacted and moved. Concrete of high workability is called wet or loose. Concrete of low workability is called dry or stiff. Because the commonest measure of workability is the slump test, people often define workability in terms of slump; high slump means high workability.
