Subject and UNIT: Basic Civil & Mechanical Engineering: UNIT II: k. Cement concrete
Slump Test is also known as Test for Consistency of Concrete. The object of this test is to study the Workability of the concrete mix. Workability means the ease with which mixing, handling and placing of concrete can be done.
Subject and UNIT: Basic Civil & Mechanical Engineering: UNIT II: k. Cement concrete
It is prepared by using light weight aggregates of loose porosity, namely, crushed light weight stones and fly ash. Its weight and cost are about 40% of plain concrete.
