PRORESIST – Calcium Aluminate Concrete

This type of concrete contains cement with a high proportion of calcium aluminate. The CAC cement (calcium aluminate cement) has a series of characteristics that give the concrete a great capacity to resist extreme conditions of abrasion, resistance to high temperatures and chemical attacks, among others. The texture of PRORESIST is similar to that of conventional concrete although it is more sensitive to curing on site due to its high hardening speed.

Description

Additional information

Field of application

  • Refractory concrete and concrete exposed to high temperatures.
  • Rapid emergency repairs.
  • Marine works, sewage networks, sewage systems, etc.
  • Pavements with high rolling interference: airport runways, roads, hangars, sheds, etc.
  • Pavements exposed to chemical attack: petrol stations, oil, slurry, brewery, wine, paint, paper, etc.
  • Tanks and reservoirs for drinking water, non-potable water, waste water, corrosive liquids, etc.
  • Tanks and tanks for leachate retention in the waste sector.
  • All those applications in which the product can replace coatings, thus saving periodic maintenance times, production stoppages, power cuts, etc.

Advantages

FAST RESISTANCE DEVELOPMENT

  • In 24 hours, strengths equivalent to those achieved after 28 days with portland cement concrete are reached.
  • Commissioning 6-8 hours after application of the product.

RESISTANCE TO HIGH TEMPERATURES

  • Resists temperatures of up to 1.200ºC, depending on the nature of the aggregate used.

RESISTANCE TO CHEMICAL ATTACKS

  • Resistant to different chemical compounds, especially chlorides, sulphate water, gypsiferous soils, magnesium salts and diluted acids.
  • Resistant to chemical and bacteriological corrosion.
  • Suitable for Qa – Qb environments.
  • Resistant to corrosion caused by materials with pH>3.5.

HIGH ABRASION RESISTANCE

  • High wear resistance in wearing courses and in areas where there is a continuous or discontinuous flow of highly abrasive materials.
  • Suitable for environments

E. RESISTANT TO EXPOSURE IN MARINE ENVIRONMENTS

  • Suitable for environments IIIa, IIIb, IIIc.

Application system

  • Always by specialised equipment.
  • The application is similar to that of conventional concrete. It requires special care in curing during the first 24 hours.
  • The application can be done by bucket, with direct or pumped pouring, depending on the customer’s requirements and access to the pouring points.
  • Other supply formats according to customer requirements: sack, big-bag and bulk silo.
