No Steel Concrete

Description:

Cemix No Steel Concrete is a 28 MPa construction-grade concrete, consisting of a uniformly blended and properly proportioned mixture of aggregates, cement, air-entraining admixtures and special synthetic reinforcing fibres. This is an excellent product for all types of general DIY concrete applications.

Typical Applications & Uses:

  • General DIY concrete applications
  • Concrete projects 40mm thick or more
  • Workshop floors, driveways, floors, patios & sidewalks in residential situations

Advantages:

  • Significantly reduced cracking from drying shrinkage
  • Superior workability
  • Air entrainment for improved freeze-thaw durability
  • Greater impact resistance

Mixing:

Empty contents into a wheelbarrow or mechanical mixer or onto a smooth non-porous surface. Add water gradually, mixing thoroughly until a workable mix is achieved. Under ideal conditions a bag of 25kg would require about 2.5 litres of water. Use the mixed concrete immediately, do not allow to the mix to stand.

Application:

Dampen the substrate before the concrete is placed. Upon placing the concrete at site, work sufficiently to remove air voids if any and compact well with a tamping rod working into all areas. Level off the corners and finish flat with a wooden float for coarse finish or a steel trowel for a smooth finish. Use Cemix® Concrete Cure WB to cure concrete, or just keep the surface damp for the first 7 days.

Note:

Fibers in this mix will resist cracking and thus not prevent cracking caused by overloading the slab with weight or due to movement in the substrate. For commercial heavy-duty slabs please follow the engineers design guidelines.

Materials:

Cemix® No Steel Concrete mix consists of a uniformly blended, properly proportioned mixture of stone, gravel, sand, cement, fibres and other admixtures approved for use in concrete to improve workability and performance of the product.

Technical Data:

Strength (MPa) – 17MPa @ 7 days, 28MPa @ 28 days.

Application Temp – 5oC - 30oC

Yield / Coverage - One 25kg bag will approximately produce a slab equivalent to 1000 x 300 x 40mm (0.012 cubic meters).

Packaging – 25kg.

The data shown above reflects typical results based on laboratory testing under controlled conditions. Reasonable variations may occur on site.

Limitations:

Where substrate movement is a possibility, we recommend the addition of steel to complements the benefits of fibre.

Storage:

Cemix® No Steel Concrete in a cool dry area. Use within six (6) months.

Cleaning:

Clean all tools with water & brush immediately after use.

Precaution:

Hazardous - portland and blended cement. This product may contain Crystalline Silica. Cements may cause respiratory, skin and eye irritation. Wet cement can be irritating and corrosive to eyes and skin; and may cause skin sensitization (dermatitis). Repeated inhalation may cause bronchitis, silicosis and lung cancer and increase risk of scleroderma.
