Here I will tell you the meaning of lumpsum in a simple way, have a look;
Meaning Of Lumpsum:
The lump-sum is simply a single payment of money which is opposed to a series of payments made over time such as an annuity.
The quantity of steel is different in different structural elements because the load taken by different elements are different.
- Slab or lintel – 0.7 to 1% (55 to 78.5 kg per metre)
- Columns – 0.8 to 6% (62.8 to 471 kg per metre cube)
I hope so your doubt is clear.
Thank You.

Particulars OPC PPC Name Ordinary Portland Cement Portland Pozzolana Cement IS Codes OPC 33 Grade Cement is IS: 269, for 43 Grade Cement IS: 8112 is used and for 53 Grade Cement IS: 12269 PPC IS 1489 (part 1 & 2) 1991 Ingredients & Manufacturing process Cement is made by heating limestone (CaCO3 & clay) to 1450oC in a kiln & grounded with gypsum. Pozzolana materials like fly ash, volcanic ash are blended to OPC @ 15%-35% by wt. Environmental impact Uses limestone clay & gypsum which are natural stones & emits CO2 during making. Consumes industrial wastes such as fly ash, bf slag, etc. & is environment friendly. Grades available 33, 43, 53 Grades Don’t have any grade but attains strength of 33 grade cement on 228 days curing. After that its strength gain slows down. Cost per unit Costly compared to PPC due to limestone Cheaper bcoz limestone replaced by pozzolana Sulphate resistance Less durable in aggressive weather & sulphate attack & hence not preferred for marine structures, hydraulic structures, sewages pipes, etc. Highly resistant to sulphate & used & preferred for marine structures, hydraulic structures, sewages pipes, etc. Permeability & Durability Low fineness, permeability is less Higher fineness, higher permeability, result high durability. Setting time Initial setting time: 30mins Final setting time: 280mins
Initial setting time: 30mins Final setting time: 600mins
Construction speed Faster construction speed as it gains strength early. Gains strength with time. Fineness OPC has finiteness of 225 sq.m/kg. It has lower fineness than PPC. So, it has higher permeability resulting lower durability. PPC has finiteness of 300 sq.m/kg. It has higher fineness than OPC. So, it has lower permeability resulting in higher durability. Heat of Hydration It contains active salt hence more Heat of Hydration. Don’t have blended material & it gains 95% early strength in 7 days. Blended cement with flyash or slag, etc. Low heat of hydration. Gains 75% strength in 7 days & 90% strength in 14 days. Shrinkage cracks Will be more due to high heat of hyudration Less shrinkage cracks Workability Lower Lower Mass concrete Not preferred Preferred for mass concreting
