| Hand/Manual/Site Mix | Ready Mix Concrete |
|---|---|
| Fairly difficult to achieve consistency since it is manually mixed at the site. | Concrete mortar is consistent since it is computerized machine produced. |
| Requires more labor force both skilled and unskilled for mixing the mortar and shifting it, laying and compacting. | Skilled labor required only to lay and compact the concrete as per the design. |
| Respective structural Engineer/ Architect will provide the details of Concrete Grade whether it is M20, M25, M30 etc. and the thickness of the concrete mould. | Respective structural Engineer/ Architect will provide the details of Concrete Grade whether it is M20, M25, M30 etc.. and the thickness of the concrete mould. |
| Requires proper estimation the material sand availability at the site ahead of schedule. |
Material procurement not a concern but proper concrete estimation needs to do. However, the RMC agency should confirm the materials used in the mortar which may include Fly ash, GGBS, Chemicals etc. |
| Requires approximately 50% more time compared to RMC. | Requires approximately 50% less time compared to Site Mix. |
| Requires enough space to accommodate materials and site mix machinery. | Requires a road width of minimum 30 feet for smooth maneuvering of the RMC carrier vehicle. |
| Monitoring the concrete mortar mix ratio through the process is critical. | The owner should obtain the cube test report from the RMC Company. |
| Quality consistent materials are very critical to achieve the concrete compression strength required. | Choose certified RMC suppliers who manufacture according to IS standards and will provide cube test reports. |
| Normally not tested for site mixes. The owner can opt for cube testing by any third party testing laboratories. | Testing to be done by RMC manufacturer and no additional charges are levied. |
| Site mix is generally cost-effective compared to RMC. | RMC is costlier compared to site mix but it is very convenient. |
