Recommended: Cement type and its advantages and disadvantages pdf

Cement is a finely ground powder binder, a material that sets and hardens and can bind other materials together, when mixed with water it forms a hardening paste of calcium silicate hydrates and calcium aluminates hydrates. it evokes highly diverse reactions. Cement is used in mortar (a combination of sand and roughly burnt gypsum) and concrete (bulk rock-like building material made from aggregate, sand, and water). By modifying the raw material mix and the temperatures utilized in manufacturing, compositional variations can be achieved to produce cements with different qualifications. Cement, chemically speaking, is a product including lime as the primary ingredient, but it is far from the first material used for cementation. The Babylonians and Assyrians used bitumen to bind together burnt brick or alabaster …show more content…

Gypsum is an abundant mineral that takes a lot of forms. The main chemical substitute to natural Gypsum is FGD Gypsum(Flue Gas Desulphurization Gypsum). It is generated by coal-fired power plants. FGD Gypsum is the end product of a wet purification procedure with natural lime that is generated according to the same laws as natural Gypsum – but in a speeded-up process taking only a few hours.
Gypsum is also an indefinitely recyclable raw material. You can always reuse Gypsum because the chemical composition of the raw material in the products remains unchanged. Additionally gypsum products is counted to be one of the very few construction materials where “closed-loop” recycling is possible, where the waste is used to make the same product again.
This non-toxic mineral can be helpful to humans, animals, plant life, and the environment. While the majority of gypsum produced in North America is used to manufacture gypsum board or building plasters Natural gypsum, occurs in sedimentary rock formations, and is found in over 85

    It is unknown when people first knew about calcium and when people used compounds of calcium. Limestone is a compound of calcium and Limestone was usually used for buildings. The common name for limestone is calcium carbonate. Early Greeks and ancient Egyptians used mortar which was made from heated limestone. It was named for its natural occurrence in limestone with was a common building material, which in itself is an oxide of calcium with the molecular formula being CaCO3.

  • Calcium Silicate Concrete In The Roman Empire

    1467 Words  | 3 Pages

    Besides the known inventions and renovations of the Roman Empire, one of the building materials that the Roman Empire produced was concrete. With its strength, inexpensiveness and its easiness to work, the Roman Empire left an everlasting impact. Concrete that is a mixture of aggregate, which is usually gravel, sand or small stones, binding agents, and water is used to construct buildings and infrastructure. The first one, aggregate, gives the product its mass while the second one, binding agents, is used to harden the product. In the early times of the history, limestone powder was usually used as a binding agent in the mixture. The Romans later used “pulvis puteolanus” (pozzolanic ash), which was a fine volcanic ash as a binding agent and it allowed Romans to have strong concrete that is also durable (Yegeul, n.d.). It was easy to use

  • Essay On Taconite Mining

    2500 Words  | 5 Pages

    The Gogebic Range could potentially become the largest open-pit iron-ore mine in the world. In the United States taconite was starting to be thought of as a waste rock. But, as the supply of taconite was slowly decreasing, the mining industry suddenly began viewing taconite as a significant and valuable resource. A lot of people don’t exactly know what taconite is or what it’s used for. Taconite is a low-grade magnetic iron ore that is used to make steel (Iron Mining in the Lake Superior Basin.). Geologists say about 20% of the nation’s remaining iron is all buried in the Gogebic Range (Ron.). There will be a lot of “phases” or steps just to mine all of the taconite located in the Northland. Phase one of the site will be a functional mine of a 4 to 4.5 mile long open pit that will be around .3 to 1.5 miles wide. The mine will trail along the linear alignment of the iron formation. The first phase of this mining project will last around 35 years (Wagner). There are also many steps used in taconite mining;

  • Fundamentals of Building Construction: The Concrete

    1653 Words  | 4 Pages

    Concrete is a composite material used widely in the construction industry. Concrete is basically a mixture of cement, water, aggregates and admixture (sometimes). Cement is a fine gray powder that consists of oxidizes calcium, silicon and aluminum. The aggregate used is normally gravel, crushed stone or sand. Admixture is a solid or liquid substance that gives a certain characteristics of the concrete. The cement reacts with water chemically and binds the aggregates together through a process called hydration during hardening or curing of concrete. It means that water helps in the hardening of the concrete while the cement bind the aggregate and also react with water to form a solid mass.

  • Mining Pollution Debate Summary

    Though it has had many negative impacts on the environment in the past, mining is a vital industry completely necessary to our economy and lives. Nearly every item we use or encounter in our day to day lives is mined or contains mined products. Without the excavation of such materials things like computers, televisions, large building structures, electricity, and cars would not be possible. Virtually every technological and medical advance uses minded materials, without which millions would suffer. Some examples of minerals in the home include the telephone which is made from as many as 42 different minerals, including aluminum, beryllium, coal, copper, gold, iron, silver, and talc. A television requires over 35 different minerals, and more than 30 minerals are needed to make a single personal computer. Without boron, copper, gold and quartz, your digital alarm clock would not work. Every American uses an average 47,000 pounds of newly mined materials each year, which is higher than all other countries with the exception of Japan, which is a staggering figure representative of our dependence and need for mined minerals. Coal makes up more than half of nation’s electricity, and will continue to be the largest electrical supplier into 2020 & accounting for some 95 percent of the nation's fossil energy reserves – nine of every ten short-tons of coal mined in the United States is used for electricity generation. As the population of the world grows more mineral resources must be exploited through mining in order to support the rising demand for such products. Though it may present a hazard to the environment and those physically located nears the mines, the materials extracted from mines...

  • Development Of Concrete And The Arch

    Opus caementicium or Roman concrete is a synthetic construction substance that’s composed of an aggregate, a binding agent, and water. In Rome’s case, as discovered by UC Berkley with the extensive analysis of a sample of Roman concrete taken from a breakwater in Italy’s Pozzuoli Bay it was developed by using lime and volcanic rock which formed a mortar, the mortar and volcanic rock were then packed into wooden forms and when seawater was added a chemical reaction occurred, bonding everything together to create concrete (History, 2013). It is uncertain when Roman concrete was developed, but it was clearly in widespread and customary use from about 150 BC; some scholars believe it was developed a century before that.

  • Architect Essay

    1196 Words  | 3 Pages

    Every person with a job, no matter what occupation, makes an impact on society in some way, shape, or form. Some people leave their legacy by defending people in court, some saving lives in a hospital, and others planning and building works of construction. These planners have a large-scale effect on everybody in society and have an eye for detail, as well as enjoy using mathematics to ensure proper construction. That is why I have chosen architecture to be my career. An architect is a person who designs buildings and supervises their construction. A broader view of an architect is a person who is responsible for inventing or realizing a particular idea or project. Architecture varies from the pillars of the Greek Parthenon, to peoples’ homes. I often find myself marveling over the design of large-scale building projects such as the skyscrapers of New York City. Most of these buildings belong to a myriad of well-known companies such as Chase and Toshiba. That is why I have particularly chosen to become a commercial architect.
