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 RC structures compliant with EN 206 and Eurocode 2.
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 a plain / ordinary concrete) and is classified as an LWAC (lightweight aggregate concrete).
Latermix Beton 1400 t is particularly suitable for reconstruction work, for strengthening existing structures, or to prevent excessive loading in seismic zones.
Low thermal conductivity concrete: 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). Latemix Beton 1400 reduces thermal bridging (psi value ψ – linear thermal transmittance) and increases the energy efficiency of buildings
The reduction of thermal bridges is possible both in new construction and in the renovation of all construction elements in contact with the building envelope, such as: in the junction between floor slabs and exterior walls, in horizontal and vertical walls or structural slab joints, in balconies and overhangs, in other structural or decorative elements, in stair construction, as well as in details of the surroundings of openings (lintels, sills, pillars, etc.).
Using Latermix Beton 1400 reduces heat loss and avoids the risk of pathologies such as mould and condensation in the interior of dwellings, typical of thermal bridges in both renovations and new construction, without the need to use complex systems to break these thermal bridges.
The binder dosage and grading curve of the components of Latermix Beton 1400 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 batched on site.
Latermix Beton is a 100% mineral non-combustible product (Euroclass fire rating – A1) that is safe, including in the presence of fire.
High yield and transport efficiency
Lightweight means increased efficiency in both product yield and transport, allowing 60% more volume of Latermix 1400 concrete to be mixed on site compared to the same weight of traditional dry concrete.
In terms of performance, only 47 bags of Latermix Béton 1400 are needed to produce 1 m³ of in-situ concrete, compared to 80 25 kg bags for a dry concrete of ordinary aggregates.
- Structurally strengthening existing floors (in timber, steel, or concrete) by means of the composite floor construction (concrete slab overlay with connectors)
- New structural floors (steel + concrete or timber + concrete composite floors, concrete floor slabs, etc.)
- Strengthening and stiffening loadbearing masonry (edge beams, columns, etc.)
- Reducing thermal bridging in the structural elements of a building envelope
