The references suggest several Ultratech cement options suitable for construction, but don't explicitly state which is best for a Damp Proof Course (DPC). However, understanding the properties needed for DPC allows us to infer the most appropriate choice.
A DPC requires a cement that offers good workability, durability, and resistance to moisture penetration. While all the listed cements could be used, some are better suited than others.
Here's a breakdown of the listed cements and their suitability for DPC:
-
Ultratech Super Plus Cement: This cement is likely a general-purpose or premium option from Ultratech. Without specific details on its composition, it's difficult to definitively say if it's best. Generally, it's a good choice for overall construction, and could be used for DPC, but consider the other options.
-
Ultratech Weather Plus Cement: This cement is specifically designed for resistance to weathering, including moisture. This makes it a very good choice for DPC as the DPC's primary function is to resist moisture.
-
Aditya Birla Ultratech OPC 43 Grade Cement: Ordinary Portland Cement (OPC) 43 grade is a common construction cement. While usable for DPC, it may not offer the specialized moisture resistance of "Weather Plus" cement. Additional waterproofing admixtures would likely be beneficial if using OPC 43.
-
Ultratech 53 Grade Cement: OPC 53 grade is a higher strength cement. While the strength is beneficial, moisture resistance is paramount for DPC. Similar to OPC 43, additional waterproofing admixtures are recommended if using this cement for DPC.
In summary, Ultratech Weather Plus Cement is the most suitable choice for DPC among the options listed because it is specifically formulated for weather resistance, including moisture, which is crucial for effective damp-proofing. Using this cement will likely reduce the need for additional waterproofing compounds, simplifying the DPC construction process. While the other options can be used, additional waterproofing admixture would be highly recommended to enhance their moisture resistance for DPC application.
