Cement

ground, and followed its contours; obstructing peaks were circumvented or less often, tunneled through” (Ancient Roman Aqueducts, 2017). Surface sections of the conduit were cut into the ground, lined with masonry or concrete and finished with smooth cement to reduce friction and seal the joints. For conduits that ran above ground, following the contours of land, the Romans built bridges, also known as arcades, with brick-faced concrete to transport water over low spots in the terrain. Since…

Nigeria and is a major supplier to the country's soft drink companies, breweries, and confectioners. The Dangote Group has moved from being a trading company to being the largest industrial group in Nigeria and includes: Dangote Sugar Refinery, Dangote Cement, and Dangote Flour. If this industrialist decides to open a new facility in a new place, a lot will have to go into consideration, like capital available for the new project. Lets assume Aliko Dangote has decided to release a sum of $50,000…

the grain is described as a sub angular. In this section we also checked the degree of compaction or cementation and for the lower is poorly cemented (crumbles in hand) or moderately cemented (forms cliffs), it all depends were you at. The type of cement material are Calcite (it fizz), Gypsum,…

at its destination, it was the thought that counts. It’s amazing that an eleven year old and a seven year old can be so thankful for such a small gesture. Additionally, Jem and Scout were saddened and very depressed about the hole being filled with cement. “Jem was facing me when he looked up, and I saw him go stark white” “Don’t you cry, now, Scout” (Lee 83). Initially, Scout was very upset but she got over it. She was only sad because there would be no more presents. Jem, on the other hand,…

Peer Draft Visualize yourself walking by two houses. In house #1 we have a typical two-story home with grass and a concrete pathway that directs you towards a rectangular door. House #2 on the other hand, is not your ordinary suburban home. It has a dome shape that scales up to three stories high, with blue cotton balls for grass and a rainbow colored carpet that leads to a circular crimson red door that opens up to a room with a sharp peppermint scent. If you were put into a situation where…

In an outline opinion article by Lawrence Downes, expresses the idea that Crazy Horse Memorial is seen as an object that defaces nature (Downes). The memorial might have a use for hard old-fashionable cement as the material which in the eyes of the public goes against green grassy nature. Cement can be seen as a relation to buildings in a city so some individuals would find it as a crime against green beautiful nature since cities only bring pollution to mother nature. Just by the texture, a…

As of lately, a process called hydraulic fracturing (fracking) has been all over news channels across America and other countries. Hydraulic Fracturing is defined as a process by which fractures in the rocks below the Earth's surface are opened and widened by injecting sand and/or chemicals at high pressure to extract natural gas or oil ("What is Fracking?"). Fracking is used to extract shale gas, tight sand gas, tight sand oil, and coal seam gas (better known as methane). Hydraulic fracturing…

Donald trump’s idea to build a wall along the Mexico border is a pointless task that is flawed in nearly every aspect. The cost to build such a wall is ludicrous, with $15 billion dollars standing as a low estimation of cost, and the price tag only increasing with the inclusion of patrols, maintenance, and wiring. The political impact would be devastating as well, and people can look to the past for evidence of that. The best part of all though is that nothing would change if it were constructed…

Observations The several ecological factors discussed in the introduction were contrasted with the study site. The first site was analysed during high tide. Several aerate rocks occupied the rocky shore of the particular site. No presence of barnacles was noted. There were several favourable abiotic and biotic factors within this microhabitat. These included tidal action, salinity, availability of nutrients and lack of diversity within the competition of space and lack of predators. Despite…

Fracking is the process of drilling deep into the earth’s crust and injecting water, sand and chemicals under immense pressure in order to obtain natural gas. With this process there are benefits and also disadvantages. There are many risks to groundwater from surface spills that are associated with shale energy development, they can be managed or mitigated by following certain precautions and steps. Groundwater is present throughout the atmosphere. There is surface water, atmospheric water and…
