Permissible Range for Using the CapcoProof WP in Concrete:
The allowable range for using The CapcoProof PW is from 1% to 3% of the cement content (1000 to 3000 grams per 100 kg of cement material weight including cement, silica fume, slag, fly ash, and other similar pozzolans). The concrete mix design, the thickness and volume of the section, and the required amount to reduce permeability are the main indices to determine the amount of using this admixture. The optimum amount of this admixture is obtained by considering the aforementioned indices and carrying out the required tests in the laboratory.
Note: This product only damp-proofs the concrete with high quality; i.e. in case of an improper mix design, a lot of porosity, and large capillary canals, this admixture is not able to damp-proof the pores. Therefore, a proper mix design and a standard implementation of concrete are the first conditions to damp-proof the concrete, and the damp-proofing materials act as complementary.
How to Mix the CapcoProof WP with concrete:
The CapcoProof WP must be added to the mix in the batching plant while adding other components in the mix. Besides, the following notes must be taken into consideration:
- Mix the concrete for 2 to 5 minutes after adding the admixture and assure the uniform distribution of the admixture in the concrete.
- The damp-proofing powder must not be added to the truck mixer containing ready-to-use concrete
