IS 2645 : 2003 Integral Waterproofing Compounds for Cement Mortar and Concrete - Specification
ICS 91.100.10;91.100.30 | CED 2 |

Reaffirmed 2022 |
1 Scope
This standard covers the requirements for integral waterproofingcompounds for cement mortar and concrete which shall be assessedby:
a) The permeability to water of the specimen made from cementsand mortars, with and without addition of waterproofing compoundunder test, by measuring the percolation of water through standardspecimen cylinders.
b) The physical tests of setting time and compressive strengthof cement by admixing the recommended proportions of themortar/concrete waterproofing compound and comparing the results ofsimilar tests on the same cement without addition of the compound.
Note 1 - Integral waterproofing compounds for mortar andconcrete shall be used in such proportions as recommended bymanufacturer but not exceeding 3 percent by weight of cement.
Note 2 - For the purpose of all the requirements in thisstandard, cement shall mean ordinary Portland cement 33 Grade, 43Grade or 53 Grade conforming to IS 269, IS 8112 and IS 12269respectively. By agreement between the purchaser and the supplier,testing of waterproofing compounds may be done with Portland slagcement conforming to IS 455 or Portland pozzolana cement - Fly ashbased conforming to IS 1489 : Part 1 or Portland pozzolana cement -Calcined clay based conforming to IS 1489 : Part 2.
