Description

Technical Properties

The results listed below were achieved by assessing the mechanical properties of a 3:1 sand: cement mortar containing RAK Bond-SBR in the proportions 8 kg per 50 kg cement against a 3:1 sand:cement control mortar. The test methods used were in full accordance with BS 6319 at 28 days-air cured.

Test Method Typical Result Control
Compressive strength (BS 6319, Pt 2) 36 N/mm2 28 N/mm2
Tensile strength (ASTM C-190) 6.2 N/mm2 2.6 N/mm2
Flexural strength (BS 6319, Pt 3) 11.8 N/mm2 7.2 N/mm2
Slant shear bond (BS 6319, Pt 4 1984) 39 N/mm2 2.8 N/mm-1
Solid content 48%

Uses

For bonding new concrete to old, tile bedding and fixing of slip bricks.

Waterproofing Internally

  • Basements
  • Swimming pools and showers
  • Potable water tanks and towers
  • Sludge tanks and ducts
  • Tunnels and underpasses
  • Computer and plant rooms

Waterproof/Protective Slurries

  • Potable water sewage and mild chemical holding tanks
  • Porous concrete, blockwork or brickwork.
  • Long term protection/reinforcement for concrete.

Waterproofing non-slip finishes

Car Decks, Walkways, Balconies, Staircases

Repair of Concrete

Weatherproof protection and making good:-

  • Spalled or damaged concrete
  • Beams and panels
  • Floor patching

Topping

As an admixture for cementitious systems, RAK Bond-SBR improves the durability, waterproofing and aberration proofing of mortars.

Workability

Mortars based on RAK Bond-SBR will remain workable for about one hour approximately.

Application

Surfaces should be clean of sand and free from oil, grease and loosely adhering particles. Hot, exposed, absorbent surfaces should be dampened prior to application or primed with a mix of 1:10 (RAK Bond SBR to Water.

Health & Safety

As with all chemical products, caution should always be exercised. Protective clothing, such as gloves and goggles, should be worn (see packaging for specific instructions). Treat any splashes to the skin or eyes with fresh water immediately. Should any of the product be accidentally swallowed, do not induce vomiting but call for medical assistance immediately. Ensure the container is available for the medical attendant to examine any relevant instructions and contents details. Reseal all containers after use and ensure product is stored as instructed on the safety section of the labelling immediately.
