Asphalt-“Asphalt” is a dark brown to black, highly viscous, hydrocarbon produced from petroleum distillation residue. This distillation can occur naturally, resulting in asphalt lakes, or occur in a petroleum refinery using crude oil. Slurry-Slurry seal involves a creation of mixture of asphalt emulsioon and fine crushed aggregate that is Spread on the surface of a road chip seal-Chip seal involves spraying the road surface with asphal emulsions followed by crushed rocks or gravel Heat island-The term "heat island" describes built up areas that are hotter than nearby rural areas.

In India gobar or cow dung is used for the purpose of making biogas. 20% of the excreta of animals are made up of dust particles that are inorganic in nature. The percentage of the inorganic dust particles is brought down by combining water with the excreta in a 1:1 ratio. The rate of feeding of any biogas manufacturing plant that is based on dung is 3,500 kilograms per day. Under normal circumstances the microbial content of the biogas is maintained by the addition of 2% of the expended slurry of the slurry of the fresh dung. 1% calcium ammonium nitrate of the dung is combined with the slurry in such cases. At times waste of kitchens and excrement of human bodies is used in these processes. The human excreta are supposed to occupy, at the most, 3% of the slurry. The addition of human excreta is crucial in this context as it increases the amount of production of biogas. This is because human excreta have high nitrogen content. The
iga üksiku reaktsiooni käigus eraldub üks vee molekul. -Kondensatsioonireaktsioon saab toimuda vaid funktsionaalrühmade osalusel ja seetõttu on siin ahela hargnemised palju haruldasemad kui liitumispolümeerides. Tänu sellele saab siin ka polümeeridest paremaid fiibreid. Kondensatsioonipolümerisatsioonis eraldub kõrvalproduktina mingi madalmolekulaarne ühend (näiteks vesi või alkohol). Samuti need mõlemad ei lahustu vees. :) 3. -MVC - vinüülkloriidmonomeer. -Slurry PVC - läga polüvinüülkloriid. -Slurry vessel - läga reservuaar. 4. Täiteainete ülesanded plastmassides: täiteained on vajalikud polümeeri kulu vähendamiseks ning materjali omaduste kujundamiseks. Täiteaineteks võivad olla peenestatud kvarts, kaoliin, klaaskiud, tekstiilmaterjalid jms. Stabilisaatorite ülesanded plastmassides: Stabilisaatoreid lisatakse plastmassi valgus-ja kuumuskindluse suurendamiseks ning kaitseks oksüdeerumise eest.

Most coal is transported by train, but coal can also be transported by barge, ship, truck, and even pipeline. About 68 percent of coal in the U.S. is transported, for at least part of its trip to market, by train. It is cheaper to transport coal on river barges, but barges cannot take coal everywhere that it needs to go. If the coal will be used near the coal mine, it can be moved by trucks and conveyors. Coal can also be crushed, mixed with water, and sent through a "slurry" pipeline. Sometimes, coal-fired electric power plants are built near coal mines to lower transportation costs. 15.3 Types of coal Coal is classified into four main types, or ranks (lignite, subbituminous, bituminous, anthracite), depending on the amounts and types of carbon it contains and on the amount of heat energy it can produce. The rank of a deposit of coal depends on the pressure and heat acting on the plant debris as it sank deeper and deeper over millions of years. For the most
