Plum Concrete Wall Design

Since the foundation has to be rested on the hard strata of soil so plum concrete of lean ratio with 80mm 100mm size stones would be poured which will be rammed upto 1 5 m and thereafter regular designed raft footings may be laid.

Plum concrete wall design.

In this video i show 1 how we do plum concrete 2 whole process of doing. Whereas in design it was proposed that the depth of foundation for bed would be 1 5 m. Gupta author of nabhi s practical handbook on building construction the term plum refers to the hard clean natural stones used in mass concrete of foundations gravity dams embankments and other mass concrete works. A 1 5 10 plum concrete mass concrete with 25 boulders as per the requirement and as instructed by the consultant and engineer in charge including the cost of centering and shuttering as required.

By adopting modified design of retaining structures cost can be reduced by 30 to 80 due to reduction in height depending upon the slope of hill and further by 5 to 10 by use. Design of sloped retaining wall. Plum concrete is a special type of concrete which is usually done where the surface is uneven and to minimize the costing of concrete. Plum concrete can be utilized in areas that need massive concrete placements such as concrete dams or bridge piers.

Plum concrete is formed by the inclusion of medium to large stones of size up to 300mm or even larger as filler. Example 01 using plum concrete 1 3 6 sloped retaining wall. The word plum actually means large stones which are termed as boulders or coarse aggregates. It is defined as a mixture of coarse aggregate and cement that are placed below the foundation or footing of a structure so as to achieve a level surface.

Plumwall insulated concrete form bracing is a leading innovator in the field of high quality easy to use icf bracing systems. In these instances pieces of stone roughly 150millimeters in size function as coarse aggregates to mix a plum concrete. Design of slopped gravity retaining wall in excel. Plum concrete using 150 mm size plums and with an effective cement content of 177 kg m3 was used for the construction of an original dam.

Construction of retaining structures in plum concrete as suggested in this paper is not only cost effective but more stable more beautiful and easy for construction.
