چکیده
The authors of this paper use an original method diatomaceous earth fractionation, which allows for obtaining a filler with specific particle size distribution. makes it possible to separate small, disintegrated and broken diatom frustules from those maintained their form in earth. study covers range tests conducted prove that such separated diatomic fraction (3–30 µm) shows features different the base diatomite (from 1 above 40 used as epoxy resin filler. We have examined mechanical properties series diatomite/resin composites, considering weight diatoms parameters composite production process. studied composites Epidian 601 cross-linked amine-based curing agent Z-1 contained 0 70% vol. or Samples were produced by being casted into silicone molds vacuum degassing conditions and, alternatively, without degassing. results shown morphology based on affects rheological systems resin. Elongation at rupture flexural stress both raised up 35%, impact strength 25%.

Diatomaceous Earth for Pest Control
Least toxic physical and chemical solutions are often part of an IPM program. Various forms of amorphous silica are commonly used as part of this strategy. Diatomaceous earth and silica gel are used in various physical formulations with or without added pesticide. The type of silica and the formulation depend on the target pest. In this issue advantages and disadvantages of diatomaceous earth a...

Abstract—In this study, the feasibility of incorporating ceramic waste from bricks (perforated brick and double hollow brick) and extruded polystyrene (XPS) waste, is analysed. Results show that it is possible to incorporate up to 25% of ceramic waste and 4% of XPS waste over the weight of gypsum in a gypsum matrix. Furthermore, with the addition of ceramic waste an 8% of surface hardness incre...
