4. concrete Concrete is most widely used man – made material. The homogenous mixture of cement, sand and aggregate when casted by mixing it with adequate amount of water is called concrete. Most concrete is poured with reinforcing material embedded to provide tensile strength.

5. Plum concrete Plum concrete is also known as cyclopean concrete. Plum concrete is the concrete mix with plums (large stone). The coarse aggregate used in plum concrete should be 25 mm down. Plum concrete consist of 60% of concrete and 40% of large sized stone with proper anchoring of reinforcement. The proportion of plum should not be exceed 50% of the total volume of plum concrete/ plum masonry.

7. Plum concrete The stone size to be used for plum shall be between 200 to 300 mm. The stone can be basalt, trap or any other approved locally available stone with minimum crushing strength of 100 Kg / cm2 obtained from quarries approved by engineering in – charge. The length of stone should not be exceed 3 times its height. The plums are laid in layers using the cement concrete as mortar. All plums concrete / plum masonry shall be maintained wet for at least 7 days.

9. Compression testing machine The compression testing machine is used to determine compressive strength of concrete. The compression testing machine can be hand – operated or automatic.

11. Result of plum and ordinary concrete S. No. Concrete Compressive Strength (N/mm2) in 7 days 1 Ordinary concrete block 20.44 2 Plum concrete block 19.11 The result shows that the compressive strength of the plum concrete is lesser than the ordinary concrete.

12. If the compressive strength of plum concrete is less than, What the purpose of plum concrete.

13. Purpose of plum concrete Plum concrete is usually done when the surface is uneven and to minimize the costing of concrete . The plum concrete is mostly used for the purpose where the more stabilizing force i.e. downward force are required for stability. Another purpose of plum concrete is to complete the work faster. It takes less construction time than the ordinary concrete required.

14. Uses of concrete in comparison to other building material Concrete is a site made material unlike other construction materials. Other materials like bricks, stone, wood etc. cannot be mould into desired shape. Only concrete can be mould into required shape and size. Concrete is a versatile material which provide strength, durability and fire resistance etc. which is not found in other building material. CO2 emission from concrete and cement production are relatively small as compared to other building material.

15. Energy efficiency in production

16. Conclusion Here we study about the plum concrete and ordinary concrete. Mostly plum concrete is used in place where faster construction and low construction cost of structure are required. Plum concrete are mostly used in the water front structure like DAMS etc. Plum concrete is heavier in weight as compared to the ordinary concrete.
