CLC Properties




Light in Weight
  • 40% to 50% lighter than a traditional cement hollow block of equal size
  • Density ranges from 200 to 1200 Kg/m3 (water density is 1000 kg/m3)
High Compressive Strength
  • Average compressive strength of 5 MPa (vs traditional cement hollow block: 4 – 7 MPa)
  • ‘Severe Duty Grade’ impact load resistance, & shock resistant
Superior Thermal Insulation
  • Thermal conductivity of 0.1225 W/m.K (3 times higher than traditional cement hollow block)
  • Thermal resistance (R-value) of 1.63 K.m2/W & thermal transmittance (U-value) of 0.61 W/m2.K
Superior Acoustic Insulation
  • Higher acoustic insulation than concrete double wall
  • Reduces sound transmission by 44%
Low Water Absorption
  • Low water absorption with an absorption rate of 12.5% (4 times lower than traditional cement hollow block)
  • Eliminates leakage & humidity in walls
Fire Resistant
  • Fireproof & fire resistant (A1 rating per ‘Eurospecs’)
  • Fire rating of 5 to 6 hours (vs traditional cement hollow block: 55 to 75 minutes)
Eco-friendly
  • Improves internal air quality, has no manufacturing waste, & is 100% recyclable
  • Saves energy consumption (air conditioning & heating)
Reduced Structural Load
  • For a 1-way ribbed Hourdi structure: structural load reduction of approximately 30%
  • Cost savings of ~45% in steel (from slabs), & ~29% in concrete (from columns) & ~33% in steel (from columns)
