Toproc

Application

The product is available in a range of proprietary formulations suitable for many specific applications and is ideal for most industrial, commercial and infrastructure construction and repair uses.

Description

Toproc is a high performance ready mixed concrete offering clients, specifiers and contractors solutions to a wide variety of construction requirements.

It is normally laid in excess of 100 mm in depth. For applications requiring less than 200 mm, consult the manufacturer for details.

Features and benefits:

  • Offers high surface strength and low dust properties, which can often negate the need for paint or resin surface finishes.
  • The in-situ compressive strength is much higher than conventional concretes typically achieving 20–25 N/mm² at 24 hours, 60 N/mm² at 28 days although this is often exceeded and can achieve 70 N.
  • Higher flexural strength and modulus of elasticity can be achieved compared to conventional concrete.
  • Exhibits less wear and greater resistance to impact than conventional concrete, thereby reducing the life cycle costs of wearing surfaces in scrap yards, loading bays, stores and other heavy industrial environments.
  • Can be pumped more easily than conventional concretes as the inclusion of pozzolans improves its pumpable properties.
  • Resistant to carbon dioxide ingress which significantly reduces the rate of carbonation, delaying the onset of rebar corrosion.
