Light Expanded Clay Aggregate - GBC India

1 Light Expanded clay AggregateWHAT IS LECA: Leca is an acronym term for ( Light Expanded clay Aggregate ) which is produced in rotary kiln at about is imported in India by GBC :Lightness of Leca is for the multi-separated air spaces which exist inside and among the aggregates, density of aggregates, depending on the size of Leca, Is fluctuated from 380 to 710 kg/m3 SOUND INSULATION: Leca Aggregate and block are among the best insulating materials and according to conducted tests, sound in Leca blocks with 10 cm width and 15 cm width respectively fades 45db and 46 db and refers to relavant standards codes are suitable for most of purposes. THERMAL INSULATION: Thermal conductivity coefficient for LECA Aggregate is about < < and for with density of 800 kg/m3. the results have tested for the high quality for insulating feature of Leca products.

2 OyNON-DECOMPOSABILITY: Leca Aggregate strongly resists against alkaline and acidic substances and pH of nearly 7 makes it neutral in chemical post reaction with concrete. WATER ABSORPTION: For closed inside porousness, average water absorption of Leca Aggregate (0-25 mm) is about 18 percent of volume in saturated state during 72 hours. APPLICATIONS AND ADVANTAGES: LECA aggregates are available in various usual gradations are 0-4mm, 4-10mm, 10-25mm and 0-25mm. Leca bulk dried density and their applications for different gradations are illustrated in table below:Leca wide applicabilityLeca GradationDensity (Max)Leca Light Weight Concrete, Light weight block, Prefabricated Panels&Slabs.

4 Leca lightweight concrete block: Leca block (back) is produced by mixing of Leca aggregates, Cement, sand and water. Using of Leca Aggregate decreases the concrete density. ADVANTAGES: 1- Lightening up to 30% of dead Self thermal & Sound Insulation 3- Appropriate Behavior in Earthquake. Low Module of elasticity of Leca Concrete, and having cement base material as well as its mortar, in addition to the lightness, reduces the destructive effects of earthquake on structure. Shapes of Leca blocks are designed for conducting vertical mortar in joints which minimizes the rubble threat. Referring to mentioned reasons, using of Leca blocks prevents buildings from asymmetric settlement and other detrimental side effects. 4- Physical Operation: Leca Blocks are suitable for any physical operation like cutting, nailing, transfixing and ridge extending to make proper route for wire, pipe and othe installing components without any cracking.

5 5- Accelerating Construction, Saving time, Labor, and material: For lightness and different sizes and dimensions of Leca blocks, walling up could be done in high speed which leads to save time, labor and material.

Leca blocks are designed in a way not to be only lightweight but cover all required. FLOORING AND ROOFING: Lightness, insulating, durability, non-decomposability, structural stability, and chemical neutrality features are collected in Leca as the best lightweight Aggregate for flooring and roofing and in the most suitable and reasonable replacement for pumice, scoria andpolystyrene, moreover Leca aggregates are used to mark insulating lightweight concrete for all floors substructures under stone, marble or ceramic etc.

6 LECA Aggregate IN AGRICULTURE: Leca prepares the best convenience bed for growth of plants due to:Ventilating of the soil and root, preventing soil from evaporation and saving water for sponge like body of Aggregate , water feeding adjustment, lightness insulation, chemically neutral, environmental-friendly, cleaner than soil and no pestilential effects on soil, plants or your : Being utilized in house waste water treatment as Leca-made filters, is supported by its features in question. Leca built home keeps you warm in winter and cold in summerFor more details contact: Advantages:AGRILECA: Expanded clay WITH SPECIFIC PH FOR HANGINGGARDENS, NURSERY-GARDENING AND HORTICULTUREA special LECAAgriLeca is the Italian-made Expanded clay designed specificallyby Laterlite for flower-growing, horticulture andgardening which uses top quality and selected raw materials toobtain, besides the renowned advantages offered by Leca, alsoa very low salinity does not contain organic substances, does notdecompose, and is rot-free and to useAgriLeca can be kept for an unlimited time, without ever in bags it is easy to use, store, carry and is produced in two different grain sizes, 3 8 and 8 15.

7 It is supplied pumped with tank trucks, loose in dumpers or in50 liter plastic bags (20 bags per m3 , in pallets of 65 weight approx. 440 Kg/m3 (22 Kg/bag) for sizes 3 8 andapprox. 380 Kg/m3 (19 Kg/bag) for size 8 pHIts pH is between 6 and 7. Fields of Use:Mixed in the soil or as a draining layer or humidity preservationlayer for hanging gardens, flower pots and plants in up of surfaces for the cultivation of vase of flower pots, of Use:VASE PLANTSAgriLeca, in peat substrates limits excessive water retention, enhances drainage and increases the porosity for the air, anessential factor for the proper growth of roots and plants; a humid but not wet soil limits the formation of rotten roots and parasite fungus. AgriLeca does not release any salinity and does not change the pH factor of the mixture, thanks to its low buffer does not turn yellow, does not pack down, doesn't change or decompose in time or due to humidity; it's aesthetically nice to see.)

8 The quantities for the AgriLeca mixture with peat or the already prepared peat substrate, must be chosen by the flower-grower according to the plant, the peat, the irrigation times used in the greenhouse. Generally it ranges from 20% (1 part of AgriLeca every 4 of peat) to 40% (2 parts of AgriLeca every 3 parts of peat).HANGING GARDENSAgriLeca is the right product for creating lightened draining layers for plants and hanging gardens. In the mixtures with the cultivation soil, it assures lightness to the structure and a water and air reserve for the plants. AgriLeca is perfect for filling flower pots and boxes. It can be supplied with dumper trucks or tank trucks equipped for vertical pumping up to 30 m or horizontal up to 80 100 POT ARRANGEMENTAgriLeca has a pleasant aesthetical appearance, and has become a must for plants cultivated in vases.

9 The brownishround (not spherical) granules are a natural finishing for flower pots and flower FILLINGAgriLeca is used to fill boxes and assures a constant temperature, drainage, humidity level and no maintenance, especially when the roots stick out of the IN GREEHOUSE CONTAINERSThe soil in the containers is subject in time to pressing due to its weight and the water. Adding AgriLeca significantly and permanently improves its porosity features for air and drainage, thus avoiding the suffocation of the roots and enhancing the overall result. Furthermore, the soil, with 20-30% of AgriLeca, reduces the excessive weight of the containers, yet assuring the necessary is also useful when moving plants from the container to the customer's garden. A layer of AgriLeca on the bottom of the hole assures drainage and the right level of humidity so the plants take root is the ideal substrate for hydro-culture.

10 The minimum level of salinity released assures the inertia of the substrate, primary condition for the proper operation of the system. It is also lightweight and easy to handle, it has moderate waterretention and excellent porosity for air. The shape and the different sizes of the grains are such as to bound well and assure a good support to plants, even tall and heavy Expanded clay Aggregate (Leca) is a great growing medium for all plants. It provides excellent drainage as well as moisture retention. Use it as a decorative mulch for potted plants, in ground plants, as an add mix to containers, and as a bottom layer for drainage. It is also widely used in hydroponic growing and is pH neutral. The pores in the stones store water and release water when required therefore providing an excellent environment for root development.
