Integral waterproofi ng admixture based on crystalline formation to produce water tight concrete

Struseal C512 is an integral waterproofing admixture to produce water tight concrete. The active chemical in Struseal C512 react with moisture available in concrete to produce non soluble crystalline formation throughout the pores of capillary tracks thus making concrete permanently sealed against water penetration from any direction.

Standard Compliance

Struseal C512 has been tested in accordance with various standards such as IS 516 Part-2 Sec-1, IS 3085-1965 (Reaffirmed 2021), ASTM C 1260, ASTM C 1202-12, AASHTO T 277, ASTM C 1556-04, 1152/C, 1152M-04, DIN 1048, B S E N 12390 – part 8.

Typical dosage

Recommended dosage of Struseal C512 is 0.6% to 1% by weight of total cementitious content. The optimum dosage of optimum to meet specific requirement should always be determined by conducting laboratory and batch trials.

Instructions for use

• Compatibility: Struseal C512 is compatible with our water reducing admixture when used in the same concrete mix, but should be added to the mix separately. The resultant properties of mixes containing more than one admixture should be assessed by the trial mix procedure recommended on this data sheet. Struseal C512 is suitable for use with all types of Portland cements, SRC cements and cement replacement materials such as PFA, GGBFS and microsilica.
• Dispensing: The optimized quantity of Struseal C512 must be added directly into the wet concrete at the time of mixing. For Ready Mix Plants, Struseal C512 can be added at site and mixed to ensure uniform distribution throughout concrete mix. In order to obtain uniform distribution, each kg of Struseal C512 must be mixed with one litre of water to form thin slurry form. Then Struseal C512 slurry shall be dispensed into transit mixer and mixed well before pumping or placing. Suggest not adding Struseal C512 powder directly into concrete. Make sure that water used for preparing slurry must be deducted from concrete total water to ensure designed water cement ratio. Consult with Strumix technical department for additional information.
• Curing: As with all structural concrete and sand : cement mixes, good curing practice should be maintained, particularly in situations where an overdose has occurred. Water spray, wet Hessian or a Strucure WS spray applied curing membrane should be used.

Packaging & Storage

• Packaging: Struseal C512 is available in 20 kg bags.
• Storage: Struseal C512 has a minimum shelf life of 6 months provided the temperature is kept within range of 5 oC and 40 oC.

Health and safety

Struseal C512 is alkaline and should not come into contact with skin and eyes. Avoid inhalation of dust during mixing. Gloves, goggles and dust mask should be worn. If contact with skin occurs, wash with water. Splashes to eyes should be washed immediately with plenty of clean water and medical advice sought.

Fire

Struseal C512 is non-flammable.
