Concrete types

Concrete types

The list below follows the lines published on the institutional site. The final specification depends on the design, the applicable standard and the plant.

Conventional

Concrete placed by buggy or crane when pumping is not the method used on site.

Applications

  • General building work

Benefits

  • Cost and material waste differ from site-mixed concrete.

Pumpable

A mix designed to travel through the pump line to the placing point.

Applications

  • Hard-to-reach jobs, height or long distance

Benefits

  • Pumping reduces manual transport inside the site.

Self-compacting

A highly fluid concrete that fills forms and dense reinforcement with little or no vibration.

Applications

  • Special foundations, densely reinforced elements and concrete walls

Benefits

  • Flow does not remove the need to control formwork and curing.

Floors

Concrete for industrial floors and yards. The institutional page cites a minimum characteristic strength of 30 MPa.

Applications

  • Industrial floors and yards

Benefits

  • Finish and joints follow the floor design.

Extruded

A dry-consistency concrete used in extrusion equipment for curbs and barriers.

Applications

  • Curbs, gutters and barriers

Benefits

  • Output depends on the extrusion equipment.

Pavements

Concrete for roads, proportioned around flexural strength and surface wear.

Applications

  • Urban roads, bridges and runways

Benefits

  • Durability depends on design, execution and traffic.

High performance

Concrete with mineral additions and special admixtures when the job requires higher strength and durability.

Applications

  • Special works, repair, precast and prestressing

Benefits

  • Additions and strength are defined with the designer.

Low permeability

A low water-cement concrete used where water ingress must be limited.

Applications

  • Hydraulic works, treatment plants and dams

Benefits

  • Low permeability does not remove joints, specified waterproofing or curing.

Pervious

A porous concrete with connected voids that let water pass through.

Applications

  • Drains, parking and permeable fill

Benefits

  • Performance depends on the subbase, maintenance and fines content.

Colored

Pigmented concrete used when color is part of the finish.

Applications

  • Floors, sidewalks and exposed elements

Benefits

  • Final color varies with cement, curing and exposure.

Lightweight

Concrete with lightweight aggregate, used when structural weight must be reduced.

Applications

  • Fill and elements where self-weight matters

Benefits

  • Strength and density are specified together.

Heavyweight

Concrete with high-density aggregate, used for shielding and ballast.

Applications

  • Shielding and counterweights

Benefits

  • Handling must account for the high weight.

Fiber-reinforced

Concrete with fibers that help control cracking and toughness.

Applications

  • Floors, pavements and elements that require toughness

Benefits

  • Fiber alone does not replace design reinforcement.

Shotcrete

Concrete sprayed onto a surface, common in retention, tunnels and repairs.

Applications

  • Retention, tunnels and repair

Benefits

  • Dry or wet process and the spraying crew are part of the service.

Roller-compacted

A dry concrete spread and compacted with rollers.

Applications

  • Dams and large areas

Benefits

  • Execution requires planning of lanes, compaction and joints.

Cooled

Temperature-controlled concrete, sometimes with ice, for large placements.

Applications

  • Foundation blocks and mass elements

Benefits

  • Placing temperature is defined by the thermal design.

Urban concrete pavement

A system of cast-in-place slabs with structural macrofibers, described for urban traffic loads.

Applications

  • Urban streets

Benefits

  • Thickness, fiber and base are defined for the traffic of the stretch.

Fine concrete

A fine-concrete line associated, in the published ecosystem, with the GreenMix operation.

Applications

  • Thin layers and specific leveling

Benefits

  • Availability may depend on the plant and the line partner.
