This experiment aims to examine the strength characteristics of structural light weight concrete generated by substituting aggregates like Cinder (class-F) and ECA for coarse aggregate in M30 grade concrete. Lightweight is created from cinder ECA, with cement substituted at 40%, 50%, 60%, 100%. The mix design project 1:1.24:0.63. Using aforementioned percentage, we cast 15 brick specimens measu...

Partially exfoliated poly (methyl methacrylate) (PMMA) / montmorillonite clay nanocomposite was synthesized via the free radical polymerization of MMA in the presence of alkyl ammonium substituted polysilsesquioxane surfactant-modified clay and AIBN initiator in supercritical CO2. MMT clay was initially cation exchanged with the surfactant to enhance its hydrophobicity and to expand the interla...

Our study was to develop a rapid and successful method for promoting asymbiotic seed germination and growth and development of protocorm like bodies (PLBs) and subsequent plantlets of Phalaenopsis orchid. Four basal media i.e. Murashige and Skoog (MS), half strength MS (½MS), Knudson C (KC) and, Vacin and Went (VW) supplemented with coconut water and peptone were examined for their effectivenes...

Objective. The aim of the study is to effect preliminary electrical heating concrete mixture on structure and properties heat-resistant expanded clay a composite binder before drying at temperature 105°C. Method. It based domestic foreign experience in studying various concretes, including ones. Result. A laboratory stand for mixtures has been developed tested. influence electric process self-s...

Lightweight Expanded Clay Aggregate (LECA), a clay-based lightweight aggregate expanding after burning at high temperatures, is among the promising material since it can be used as construction materials for buildings and roads, geotechnical fillings, hydroponic growing medium, humidity control, wall damper, heat insulation, water treatment, others. However, potential of clay from various place...
