Instead of compost or fibre, small pebbles or expanded clay
particles are used for potting bulbs in exactly the same way.
Technology of receiving expanded clay
from poorly swelling up clay raw materials.
Considerable differences in effectiveness of fibres strongly depend first of all on aggregate type (polystyrene, pumice, expanded clay
, sintered fly ash), secondly on fibre type (straight or hook ended; 5 to 50 mm long) and its content (0.
The report is devoted to research of expanded clay
market in Russia in 2007 - 6 months 2010 and forecast of its development till 2012.
Follow with a 4cm layer of crushed brick, limestone chippings, gravel or expanded clay
Topics of the 148 papers include the design and testing of prestressed square concrete piles, the performance of expanded clay
shale as an embankment backfill, the mechanical properties of an asphalt mixture with bottom ash aggregates, and modeling instruction in an environmental geotechnics course.
Instead, you use inert medium such as rockwool, expanded clay
, silicate rock, and coir (coco fiber) for plant support and moisture/ nutrient retention in the root zone.
Advances will be spurred by environmental and land use concerns favoring recycled and secondary aggregate materials, and by rising demand for specialty products such as expanded clay
and shale, which are used in applications like bridge decks, where light weight is of extreme importance.
from Norway, known as Leca, replaced the expanded shale media because of quality concerns.
Transportation will be held between plants, the premises belonging to the Purchaser and PKL Expanded clay
Instead of potting compost or fibre, pebbles or expanded clay
particles are sometimes used, the only disadvantage being that it is difficult to see when the bulbs need watering as the surface of the pebbles always looks dry.
