Burlap
Hessian (, ), burlap in North America, or crocus in Jamaica and the wider Caribbean, is a woven fabric made of vegetable fibres, usually the skin of the jute plant or sisal leaves. It is generally used (in the crude tow form known as gunny) for duties of rough handling, such as making sacks employed to ship farm products and to act as covers for sandbags (although woven plastics now often serve these purposes), and for wrapping tree- root balls. However, this dense woven fabric, historically coarse, more recently is being produced in a refined state, known simply as ''jute'', as an eco-friendly material for bags, rugs, and other products. The name "hessian" is attributed to the historic use of the fabric as part of the uniform of soldiers from the former Landgraviate of Hesse (1264–1567) and its successors, who were called '' Hessians''. Hessian cloth comes in different types of construction, form, size and color. The origin of the word ''burlap'' is uncertain, though i ...

Sandbags
A sandbag or dirtbag is a bag or sack made of hessian (burlap), polypropylene or other sturdy materials that is filled with sand or soil and used for such purposes as flood control, military fortification in trenches and bunkers, shielding glass windows in war zones, ballast, counterweight, and in other applications requiring mobile fortification, such as adding improvised additional protection to armored vehicles or tanks. The advantages are that the bags and sand are inexpensive. When empty, the bags are compact and lightweight for easy storage and transportation. They can be brought to a site empty and filled with local sand or soil. Disadvantages are that filling bags is labor-intensive. Without proper training, sandbag walls can be constructed improperly causing them to fail at a lower height than expected, when used in flood-control purposes. They can degrade prematurely in the sun and elements once deployed. They can also become contaminated by sewage in flood waters ma ...

Gunny Sack
A gunny sack, also known as a gunny shoe, burlap sack, hessian sack or tow sack, is a large Bag, sack, traditionally made of burlap (Hessian fabric) formed from jute, hemp, sisal, or other natural fibres, usually in the crude Spinning (textiles), spun form of Tow (fibre), tow. Modern-day versions of these sacks are often made from Organic compound#Synthetic compounds, synthetic fabrics such as polypropylene. The word ''gunny'', meaning coarse fabric, is of Indo-Aryan languages, Indo-Aryan origin. Reusable gunny sacks, typically holding about , were traditionally used, and continue to be to some extent, for transporting grain, potatoes and other agricultural products. In Australia, these sacks, made of Indian jute, were known traditionally as "hessian sacks", "hessian bags" or "sugar bags." Gunny sacks are sometimes used as sandbags for erosion control, especially in emergencies. Up until the latter part of the twentieth century, when they became less common, the sacks were one ...

Root Ball
A root ball is the mass of roots and growing media at the base of a plant such as trees, shrubs, and other perennials and annual plants. The appearance and structure of the root ball will be largely dependent on the method of growing used in the production of the plant. The root ball of a container plant will be different than that of the field-harvested “ball and burlap” tree. The root ball is of particular significance in horticulture when plants are being planted or require repotting as, the quality, size, and preparation of the root ball will heavily determine how well the plant will survive being transplanted and re-establish in its new location. Root ball pruning of container grown plants Most commonly plants are grown in containers where the roots begin to circle and take the shape of their pot. The root balls that have been exposed to this scenario have a very high chance of developing circling or girdling roots that will become problematic and possibly detriment ...

Jute
Jute ( ) is a long, rough, shiny bast fibre that can be Spinning (textiles), spun into coarse, strong threads. It is produced from flowering plants in the genus ''Corchorus'', of the mallow family Malvaceae. The primary source of the fiber is ''Corchorus olitorius'', but such fiber is considered inferior to that derived from ''Corchorus capsularis''. Jute fibers, composed primarily of cellulose and lignin, are collected from bast (the phloem of the plant, sometimes called the "skin"). The industrial term for jute fiber is ''raw jute''. The fibers are off-white to brown and range from long. In Bangladesh, jute is called the "golden fiber" for its color and monetary value. The bulk of the jute trade is centered in South Asia, with India and Bangladesh as the primary producers. The majority of jute is used for durable and sustainable packaging, such as Gunny sack, burlap sacks. Its production and usage declined as Disposable product, disposable plastic packaging became common, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Carpet
A carpet is a textile floor covering typically consisting of an upper layer of Pile (textile), pile attached to a backing. The pile was traditionally made from wool, but since the 20th century synthetic fiber, synthetic fibres such as polypropylene, nylon, and polyester have often been used, as these fibres are less expensive than wool. The pile usually consists of twisted Tufting, tufts that are typically heat-treated to maintain their structure. The term ''carpet'' is often used in a similar context to the term rug, but rugs are mostly considered to be smaller than a room and not attached to the floor. Carpets are used for a variety of purposes. These include insulating a person's feet from a cold tile or concrete floor, making a room more comfortable as a place to sit on the floor (e.g., when playing with children or as a prayer rug), reducing sound from walking (particularly in apartment buildings), and adding decoration or colour to a room. Carpets can be made in any colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ...

Maroon (people)
Maroons are descendants of African diaspora in the Americas, Africans in the Americas and islands of the Indian Ocean who escaped from slavery, through flight or manumission, and formed their own settlements. They often mixed with Indigenous peoples of the Americas, Indigenous peoples, eventually ethnogenesis, evolving into separate creole cultures such as the Garifuna and the Mascogos. Etymology ''Maroon'' entered English around the 1590s, from the French adjective , meaning 'feral' or 'fugitive', itself possibly from the American Spanish word , meaning 'wild, unruly' or 'runaway slave'. In the early 1570s, Sir Francis Drake's Francis Drake's expedition of 1572–1573, raids on the Spanish in Panama were aided by "''Symerons''", a likely misspelling of '. The linguist Leo Spitzer, writing in the journal ''Language (journal), Language'', says, "If there is a connection between Eng. ''maroon'', Fr. ', and Sp. ', Spain (or Spanish America) probably gave the word directly to E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Rooibos
Rooibos ( ; , ), or , is a broom (shrub), broom-like member of the plant family Fabaceae that grows in South Africa's Fynbos biome. The leaves are used to make a caffeine-free herbal tea, herbal infusion that has been popular in Southern Africa for generations. Since the 2000s, rooibos has gained popularity internationally, with an earthy flavour and aroma that is similar to yerba mate or tobacco. Outside of Southern Africa, it is called bush tea, red tea, or redbush tea (predominantly in Great Britain). The name ''rooibos'' is Afrikaans deriving from , meaning . The name is protected in South Africa and has protected designation of origin status in the EU. Rooibos was formerly classified in the genus but is now thought to be part of , following Rolf Dahlgren, Dahlgren (1980). The specific name (botany), specific name of , for the plant's linear growing structure and needle-like leaves, was given by Nicolaas Laurens Burman, Burman (1759). Production and processing Roo ...

Cement
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime- or calcium silicate-based, and are either hydraulic or less commonly non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble. This allows setting in wet conditions or u ...
