Laterlite Latermix Cem Mini : Ultra Lightweight Insulating Concrete
LATERMIX CEM MINI : ULTRA LIGHTWEIGHT INSULATING CONCRETE
LATERMIX CEM MINI: ULTRA LIGHTWEIGHT INSULATING CONCRETE
Latermix Cem Mini is a bagged ready mix ultra-lightweight insulating concrete for screed fills, screeds, roof falls, based on special Laterlite Plus expanded clay.
Mixing Latermix Cem Mini with water makes it possible to obtain a ready-to-use, lightweight, insulating and versatile concrete that can be used both indoors and outdoors for levelling, sloping, and screeding, with the possibility of direct gluing of the floor covering and waterproofing.
CHARACTERISTICS AND ADVANTAGES
STRONG, STABLE, DURABLE, AND CE-MARKED
Latermix Cem Mini has high compressive strength (5 MPa), is CE-marked to denote conformity to EN 13813 (screed materials and floor screeds), is dimensionally stable and non-deformable, and retains its properties unaltered over time.
FOR INTERIOR AND EXTERIOR USE
Latermix Cem Mini can be used to lay screeds and falls internally or externally.
INSULATING CONCRETE
Latermix Cem Mini is 10 times more insulating than traditional concrete and screed products (thermal conductivity lambda λ =0.142 W/mK), can be used to supplement or replace the insulation on flat or pitched roofs, floor slabs, and vaults, and reduces thermal bridging. Its porosity improves acoustic insulation.
NON-COMBUSTIBLE AND FIRE-RESISTANT
This is a 100% mineral non-combustible lightweight concrete (Euroclass fire rating – A1) that is fire-resistant and safe, including in the presence of fire.
SUITABLE FOR SUSTAINABLE CONSTRUCTION
The natural raw materials used in Latermix Cem Mini, its manufacturing process, which respects the environment, and the absence of harmful emissions (even in the presence of fire), make it suitable for sustainable construction as certified by ANAB-ICEA, the Italian Accreditation Institute.
DIRECT APPLICATION OF FLOOR FINISH AND WATERPROOFING
Because of its closed surface, a waterproofing layer, ceramic and stone paving or floating wood floor can be laid on Latermix Cem Mini directly
LIGHTWEIGHT
Latermix Cem Mini weighs approx. 600 Kg/m3 when laid: less than one third the weight of traditional or flowing screeds and less than a quarter of that of structural concrete. It reduces dead loading and is particularly suitable for reconstructing existing floors, vaults, and roofs, or to prevent excessive loading in seismic zones.
MULTIPURPOSE LIGHTWEIGHT CONCRETE
Latermix Cem Mini can be used as a substrate, for incorporating services in floors, as a base or top screed, as an insulating base screed to support underfloor heating systems or for creating falls on flat roofs..

APPLICATION METHOD
BINDING WITH CEMENT
No fines concrete (pervious concrete, open-pore structure) Laterlite Expanded Clay binds easily with cement to give a light-weight insulating permeable concrete with better me- chanical strength as compared to the loose product.
TYPICAL FORMULATION PER M3
- 1 m3 (20 bags) of granular expanded clay 2-3, 3-8 or 8-20; • 150 kg of type 32.5 cement;
- 80-90 litres of clean water (or less if the material is already wet).
LOOSE APPLICATION
In order to exploit to the full the insulating and lightness char- acteristics of Laterlite Expanded Clay, the material should be laid loose and simply levelled to the thickness desired.
If the top surface is not to be walkable it can be left as it is. If it is to be accessible or walkable or if a sur-face finish, such as an impermeable layer or paving, is to be applied, it must be covered with a layer of another material (a screed, a floor slab, various types of panel, or plant growth soil), incorporating separation layers if required. N.B. the space to be filled with Laterlite Expanded Clay must be adequately contained at the sides.
SURFACE BONDING WITH CEMENT SLURRY
The topmost granules of a layer of loose Laterlite Expanded Clay can be fixed with a cement slurry to make the surface easy to walk on for completing the job (by adding a top slab, a screed, etc.). The cement slurry (a mixture of cement and water) should be spread over the surface of the loose Laterlite Expanded Clay after it has been levelled.
By varying the proportions of water and cement (w/c), the slurry can be made more on less fluid and will penetrate to a greater or lesser depth into the layer of expanded clay. The suggested approximate w/c ratio is 0.8 (equivalent to 1 no. 25 kg bag of cement + 20 litres of water).
