Integral waterproofing compounds for cement mortar and concrete — IS 2645 (2003) Testing

IS 2645:2003 is the Indian Standard for Integral Waterproofing Compounds for Cement Mortar and Concrete — Specification. It establishes requirements for waterproofing compounds intended to be mixed into cement mortar and concrete.

An integral waterproofing compound is an additive incorporated into cement mortar or concrete to help reduce water penetration. It is used in construction applications where improved resistance to moisture and seepage is required.

Products marketed as integral waterproofing compounds for use with cement mortar and concrete may require evaluation against IS 2645:2003. The standard includes provisions for both powder-form and liquid-form compounds.

The permeability test evaluates the ability of treated cement mortar or concrete to resist the passage of water. It is an important performance assessment for determining the effectiveness of an integral waterproofing compound.

Yes. IS 2645:2003 includes compressive strength evaluation at specified curing ages. This helps determine whether the waterproofing compound adversely affects the strength development of cement mortar.

The standard includes determination of initial and final setting time to assess the effect of the waterproofing compound on the setting characteristics of cement-based materials.

Yes. Chloride content is one of the specified characteristics considered during testing. Determining chloride content helps assess the suitability of the waterproofing compound for cement mortar and concrete applications.

Integral waterproofing compounds conforming to IS 2645 may be used in cement mortar and concrete applications where resistance to water penetration is important, including various building and civil construction works.
