PerlCON™ is self-compacting lightweight concrete made out of sediment-stable water-binder suspension and produced only with water, cement, cement substitutes, additives and  lightweight aggregates. Pumis expanded clay, and other lightweight aggregates can be applied for the PerlCON production. There are no fine aggregates such as sand are required, however the characteristics of PerlCON™ are comparable with C25/30 and C30/37 concrete types with significantly lower weight (approx. 1500 kg/m³). Despite the cement substitution of up to 40%, MultiCON lightweight concrete products can be produced in excavated material forms in highest quality and with efficient strength properties.


Technical Figures of PerlCON™

Cement substitution – 40%
Cement consumption 400-600 kg/m³
Gross density 1400-1700 kg/m³Hardness:
8h = 10 N/mm²,
16h =  16 N/mm²,
72h = 23 N/mm²,
28 days >33 N/mm

Slump > 93 cm
Bending compressive strength > 4,0 N/mm²
E- Module = 18.000 N/mm²
Fire protection = F180






  • Water proof according to DIN 1048 at 3.5 bar, 72h; allowed value = 50 mm, measured value at lightweight concrete = 8 mm (50 mm).
  • PerlCON™ can be pumped more than over 100 meters’ distance and heights up to 30 meters in 2 inch tubes. Moreover, it can be promoted in plastic tubes.
  • Dyeing and color concrete manufacturing is possible without restrictions.
  • 100% recyclable.

Recipe options

  • Required Cement approx. 400 – 600 kg/m³;
  • Required lightweight filler, e.g. Perlite approx. 80 – 260 kg/m³ (depends on the quality requirements);
  • Limestone powder as a substitute for cement – up to 400 kg;
  • Flow stabilizers - as required;
  • Glass fiber mat for reinforcement.


Application Range of PerlCON™

Due to its properties PerlCON is comparable with normal concrete, completely new application areas are opened up in the field of statically stressed components. Currently, investigations have been conducted in accredited universities that document this. Just the idea of houses being much lighter and smaller, blows up all the mind.

PerlCON™ does not require compaction. In this context, the impact on the global earthquake calculations problem must be pointed out. Lighter buildings with less vibrating masses cause exorbitantly less forces.

(1) Precast elements:
Double wall
Filigree slab
Solid walls
Hollow core

(2) Modules:
Modules with 40% weight reduction
Modules for low-cost housing (beams, columns, slabs)
Garages modules
Sanitary cells and blocks
Precast lightweight elements such as solid walls for housing in sub-tropic climate regions with lower insulation
Colored lightweight facades elements

(3) Low price mixed concrete plants with high-flow rate.

(4) The impact on the world’s existing problem of earthquake calculations still important to note: lighter buildings with less vibrating masses cause exorbitantly less forces
