DESCRIPTION:
SUNPLAST-AWA is a ready to use Anti Washout Polymer Compound
SUNPLAST-AWA is formulated to provide highly fluid, easily placed and consolidated concrete that will resist washout and segregation during placement and curing underwater, protecting the mechanical properties of concrete structure.
SUNPLAST-AWA enhances the performance of plastic and hardened concrete and is manufactured under rigid quality control measures to provide uniform reliable results.
USES:
SUNPLAST-AWA creates a highly cohesive mix which is resistant to segregation and washout, allowing the concrete to be pumped or tremied underwater without loss of cementitious paste, preserving the intended hardened concrete properties including bond strength, compressive strength and impermeability.
SUNPLAST-AWA enhances concrete performance and provides a means to lower construction costs by eliminating the need for costly dewatering procedures, coffer dams, sacrificial additional quantity of cement, and overall suspect quality of underwater concrete.
ADVANTAGES:
- Excellent washout resistance, protecting concrete integrity and eliminating the need to dewater placement site.
- Improved concrete quality by decreasing water-cement ratio upto 25%
- Improved workability and placeability.
- Enhanced pumpability and tremie flow.
- Extended "slump life" without extended delays in set time.
- Improved cohesiveness and resistance to segregation.
- Self consolidation reduces voids and improves structural integrity.
- Easily and accurately dispensed and mixed into the concrete/grout.
- Improved Bond strengths and compressive strengths of concrete.
- Reduced surface laitance.
- Effective and fresh and salt water environments.
SUNPLAST-AWA is recommended for use at a dosage rate of 400ml -750ml per 50 kgs bag of cement. The dosage rate of SUNPLAST-AWA is dependant on number of variables including cement content, water-cement ratio and degree for washout resistance required. Concrete temperature, ambient temperatures or designed concrete mix containing special admixtures may require dosage rates outside the specified limits. We recommend that testing be done to determine the suitability of dosage under such cases.

COMPATIBILITY:
SUNPLAST-AWA is compatible with all types of Portland cement, class C and F Fly ash, GGBS, silica fume and approved air entraining admixtures. However for best results, each admixture must dispensed separately into the concrete mix.
STORAGE AND SAFETY:
SUNPLAST-AWA should be stored in cool and dry locations, SUNPLAST-AWA may freeze at sub zero temperatures and precautions must be taken to protect it from freezing.
All necessary safety precautions like splash goggles, respirators, gloves should be kept during it recommended use. Wash hands and eyes immediately after over exposure to contents.
SHELF LIFE:
Six months when stored in closed, sealed containers.
PACKING:
20 litres, 200 litres drum.
