Groundwater samples contaminated with potentially toxic elements (PTE), including metals and nitrate ions, were collected at a depth of 8–10 m from the Siberian Chemical Plant multicomponent waste storage. The possibility developing permeable biogeochemical barrier zeolite lightweight expanded clay aggregate (LECA) was investigated. mass fraction properties several (Mn, Fe, Co, Ni, Cu, Zn, Cd, ...

Concrete developed from light expanded clay aggregate (LECA) and glass fiber has good performance, durability, sustainability. Towards this, the experimental investigation was designed to study cubes, cylinders, simply supported beams. Four mixtures had LECA volume of 0%, 75%, 85%, 95% as coarse replacement content 2% (N, L75, L85, L95), other two 75% 1% 1.5% (L75-F1 L75-F1.5). Results compared...

Substituting natural aggregates in the green roof substrate and drainage layers with lightweight artificial recycled coarse materials is an eco-friendly alternative for applying lower load to rooftops preserving resources. However, a lack of precise understanding thermal resistance, water passing ability, holding capacity materials, including has raised demand measuring their Rc-value, permeabi...

Abstract The influence of inorganic minerals (colemanite and nepheline syenite) as additives for sustainable clay brick manufacture has been examined. Each additive was added at 4 wt% to 96 samples were fired 950 °C 1040 then compared with 100% clay. Multiple analytical techniques (X-ray fluorescence, dilatometry, boiling water absorption, volumetric shrinkage, mercury porosimetry) used analysi...

Abstract The residual compressive strength of eight lightweight concrete mixtures containing three commercial grading (Liapor HD 5 N, Liapor 7 and 8F) coarse aggregate (LWA) were determined after to expose at high temperatures. Eight mixes produced, two by normal weight the rest different types LWA. produced was analyzed temperature exposure effect using LWA, type compaction method studied. To ...

Sclerotinia sclerotiorum, which causes white mold, is a widespread pathogen. In 2020, new host plant of this fungus, the watercress (Nasturtium officinale) was identified in Hungary an aquaponic system. During cultivation S. sclerotiorum detected on plant, fungus caused 30% yield loss. Fungicides should not be used against fungi systems. Non-chemical methods integrated pest management used. The...

The article investigates the possibilities of obtaining high–quality expanded clay based on Gurlen deposit Republic Uzbekistan, with additives from local oil and fat combines – gossypol pitch dune sand Tuprakkala massif. It is determined that addition to raw mixture within specified limits significantly increases swelling mass. was also mass (together pitch) in moderate quantities contributes a...
