LIGHTWEIGHT INSULATING STRUCTURAL CONCRETE. FOR STRENGTHENING FLOOR SLABS, CONSTRUCTING COMPOSITE SLABS, AND REDUCING THERMAL BRIDGING
Latermix Beton is a bagged pre-mixed lightweight insulating structural concrete based on special Laterlite Plus hydrophobic expanded clay of medium-fine grain, and is ready for use after mixing with only water.
Structural strength: Latermix Beton 1400 is a true structural concrete of class LC 20/22 (Rck 25 MPa – 250 kg/cm2) that can be used for loadbearing structures compliant with EN 206 and Eurocode 2.
Lightweight: Latermix Beton 1400 contains Laterlite Expanded Clay as a replacement for traditional aggregates that significantly reduces weight by at least 1,000 kg (1 tonne) per m3. It has a density of 1400 kg/m3 (as opposed to 2400/2500 kg/m3 of an ordinary concrete) and is classified as an LWAC (lightweight aggregate concrete). It is particularly suitable for reconstruction work, for strengthening existing structures, or to prevent excessive loading in seismic zones.
Insulating characteristics: Its lambda (thermal conductivity) is 4,5 times lower than that of an ordinary concrete (lambda= 0.42 W/mK as opposed to 1.9 W/mK). It reduces thermal bridging, increases the energy efficiency of buildings, and prevents the development of building pathologies such as condensation and mould.
Reliable performance: The binder dosage and grading curve of the components are factory checked and maintained constant. Using only water for the mix means that the performance of the completed component can be controlled effectively; this is particularly important for guaranteeing strength in structural applications and eliminates the risk and inaccuracy associated with products mixed on site.
Non-combustible: This is a 100% mineral non-combustible product (Euroclass fire rating – A1) that is safe, including in the presence of fire.
