What is Plum Concrete

Purpose of plum concrete:

Plum concrete is a special type of concrete which is usually done where the surface is uneven and to minimize the costing of concrete.
Practical Example:- below footings of residential buildings where in a small portion where the slope of ground below single footing is 1:10 to 1:50 in that case to save the cost of concrete plum is usually preferred. This finally leads to minimize the construction cost of building in all.

Uses of plum concrete:

• Plum concrete is used at the water channel beds
• It is used mostly in mass concrete works like concrete gravity dams or bridge piers In such cases pieces of rock about 150 mm in size are used as coarse aggregates to mix a plum concrete.
• It is used at side slopes of embankment to provide a protective layer to earthen foundations and bases.

Plum Concrete

What is plum concrete? In some mass concrete foundations, boulders of say 150 mm size up to 30% of the total quantity of concrete, are mixed in the wet concrete. This adds to economics and saves heat generation. Such concretes are called plum concretes.
