WOOD• Wood is a porous and fibrous structural tissue found in the stems and roots of trees , and
other woody plants. It has been used for thousands of years for both fuel and as a construction material. It is an organic material, a natural composite of cellulose fibers.
• A 2011 discovery in the Canadian uncovered the earliest known plants to have grown wood, approximately 395 to 400 million years ago.
• The chemical composition of wood varies from species to species, but is approximately 50% carbon, 42% oxygen, 6% hydrogen, 1% nitrogen, and 1% other elements (mainly calcium, potassium, sodium, magnesium, iron, and manganese) by weight.
Physical properties:• Growth rings:There are clear seasons, growth can occur in a discrete annual or seasonalpattern, leading to growtn ring and visible on the other surfaces. the partof a growth ring nearest the center of the tree, and formed early in thegrowing season known as earlywood or springwood. The outer portion formed later in the season is then known as the latewood or summerwood.
Knots:A knot is a particular type of defect in a piece of wood. it will affect the technical properties of the wood, usually reducing the local strength During the development of a tree, the lower limbs often die, but may remain attached for a time, sometimes years.Subsequent layers of growth of the attaching stem are no longerintimately joined with the dead limb, but are grown around it. Hence,dead branches produce knots which are not attached, and likely todrop out after the tree has been sawn into boards. The extent to whichknots affect the strength of a beam depends upon their position, size, number, and condition. Knots may continue to 'bleed' through to the surface of a knot for months or even years after manufacture and show as a yellow or brownish stain. A knot primer paint or solution (knotting), correctly applied during preparation, may do much to reduce this problembut it is difficult to control completely.
WOOD
• Heartwood is wood that as a result of a naturally occurring chemical transformation which occurs spontaneously . Once heartwood formation is complete, the heartwood is dead. Heartwood is often visually di All wood in a tree is first formed as sapwood. The more leaves a tree bears and the more vigorous its growth, the larger the volume of sapwood required. Hence trees making rapid growth in the open have thicker sapwood for their size than trees of the same species growing in dense forests. Sometimes trees (of species that do form heartwood) grown in the open may become of considerable size, 30 cm or more in diameter, before any heartwood begins to form, distinct from the living sapwood, and can be distinguished in a cross-section where the boundary will tend to follow the growth rings. For example, it is sometimes much darker.
WOOD
• Sapwood is the younger, outermost wood; in the growing tree it is living wood, and its principal functions are to conduct water from the roots to the leaves and to store up and give back according to the season the reserves prepared in the leaves thin sapwood is characteristic of such species as chestnut, black locust, mulberry, osage-orange, and sassafras while in maple, ash, hickory, hackberry, beech, and pine, thick sapwood is the rule.
• Sapwood is thicker in the upper portion of the trunk of a tree than near the base, because the age and the diameter of the upper sections are less. given piece of sapwood, because of its position in the tree, may well be stronger than a piece of heartwood from the same tree.
• If a tree grows all its life in the open and the • conditions of soil and site remain unchanged,• it will make its most rapid growth in youth,• and gradually decline. The annual rings of • growth are for many years quite wide, but• later they become narrower and narrower.
WOOD
Colour:• In species which show a distinct difference between heartwood and sapwood the natural
color of heartwood is usually darker than that of the sapwood color difference does not mean a difference in the mechanical properties of heartwood and sapwood, although there may be a dramatic chemical difference. Abnormal discoloration of wood often denotes a diseased condition, indicating unsoundness. The black check in western hemlock is the result of insect attacks. The reddish-brown streaks so common in hickory and certain other woods are mostly the result of injury by birds.
WOOD
Structure:Wood is a heterogeneous, hygroscopic, cellular and anisotropic material. It consists of cells, and the cell walls are composed of micro-fibrils of cellulose (40% – 50%) and hemicellulose (15% – 25%) impregnated with lignin (15% – 30%). Softwood is the source of about 80% of the world's production of timber.Hardwoods have a more complex structure than softwoods and are often much slower growing as a result. Hardwoods are employed in a large range of applications.Earlywood and latewood:The latewood will be denser than that formed early in the season. When examined under a microscope the cells of dense latewood are seen to be very thick-walled and with very small cell cavities, while those formed first in the season have thin walls and large cell cavities. The strength is in the walls, not the cavities. Hence latewood has more density and strength.In the general statement that the more rapid the growth or the wider the rings of growth, the heavier, harder, stronger, and stiffer the wood.Specific gravity:The single most revealing property of wood as an indicator of wood quality is specific gravity as both pulp yield and lumber strength are determined by it. Specific gravity is the ratio of the mass of a substance to the mass of an equal volume of water
