چکیده

Introduction: Today, the need for neutralization of environmental, economic, social, and other consequences natural emergencies is becoming more urgent. One such devastating disasters forest fires, which are currently very widespread in world. In most cases, after a fire, we left with that was partially exposed to fire. A burnt tree loses its immunity. As result, an outbreak various subcortical insect species, infect healthy trees as well, occurs these territories. Such subjected sanitary cutting. Purpose study: We aimed determine residual mechanical properties raw wood be used structural material. Methods: course study, destructive non-destructive testing methods respect Results: It established changes microstructure correlate strength properties. The maximum decrease observed at top end amounted 22.7% compared reference wood. minimum post-fire butt up 15.0%. middle part, 24.0%.

Microstructural and Mechanical Properties of Alkali Activated Colombian Raw Materials

Microstructural and mechanical properties of alkali activated binders based on blends of Colombian granulated blast furnace slag (GBFS) and fly ash (FA) were investigated. The synthesis of alkali activated binders was conducted at 85 °C for 24 h with different slag/fly ash ratios (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100). Mineralogical and microstructural characterization was carried out b...

Wood Char Depth: Interpretation in Fire Investigations

INTRODUCTION Wood char depth patterns have been considered important by fire investigators in most countries where significant use is made of wood as a construction material. This is natural, since post-fire patterns found on wood members are generally more pronounced and extensive than those found on many other construction materials. But the present state of affairs has been such that there i...

Mechanical and Microstructural Properties of Biological Materials

Biological materials, such as isolated protein networks, tissues and living cells are extremely heterogeneous and contain structures on length scales from nanometers to hundreds of microns. Their complex geometries and sensitivity to environmental conditions make traditional measurements of structure and mechanics difficult, challenging experimenters to develop new techniques. In this work, we ...
