Voidcrete

Voidcrete is a pre-bagged low-density aerated cementitious material for use in void filling applications.

 

Advantages

  • High volume yield provides economical void filling solutions.
  • Simplified equipment provides ease of mixing and aeration, with no special pre-foaming equipment required.
  • Different wet densities can be achieved without any sophisticated plant.
  • Low compressive strength provides high energy absorption characteristics.

 

Composition Description
OPC CEM 1 42,5
Optional extenders - Silica Fume / GGBS / PFA Foaming agents

 

Standards Compliance
Voidcrete materials comply with the requirements of SABS ENV 197-1,
1200G 1491-1/2/3.

Relative Density
Voidcrete normally has a wet relative density of 0,24 to 0,40. This can be varied to customer requirements by means of adjustments on the mixer/pump unit.

 

Packaging
Outer bag: Virgin, woven, pre-printed, polypropylene bag, with stitched polyester seams. Colour coded for easy identification of product.

 

Storage
Materials should normally be stored under cover. Reduced shelf life may occur if packaging is exposed to the elements. Packaging materials may deteriorate, allowing moisture ingress into the cementitious binder. This could lead to premature hardening.

 

Shelf Life
Voidcrete products will store for up to 6 months in dry conditions.

 

Safety

General The use of eye protection, gloves and dust masks is recommended. Follow the typical precautions as prescribed for handling Portland cement.
Inhalation Constant exposure over long periods of time to very high concentrations may cause a cough with phlegm.
Skin contact Prolonged exposure could sensitize skin causing mild irritation. In extreme cases, dermatitis could occur.
Eyes Use eye protection. However, if eyes become affected, irrigate eyes with copious amounts of clean water. Seek medical attention.
Ingestion Ingestion of harmful quantities is unlikely to occur. If ingested, drink copious amounts of drinking water and consult a medical practitioner. DO NOT INDUCE VOMITING.
