Recommended: Cement type and its advantages and disadvantages pdf

Inorganic: Through investigating the various properties of Cement/Concrete/Mortar, Glass, and Ceramics/Porcelain I have come to understand the chemical composition, type of bond, structure, and the daily use of each of the substances. Cement is composed of calcium which usually is acquired from limestone and silicon which is usually from sand, shale or clay (aluminosilicates). The structure of cement is in between the two extremes of an ionic and a covalent model. It is between an ionic oxide lattice and a tetrahedral covalent network. Cement when wet or when dry has both cohesive and adhesive properties. Concrete is created through the mixture of cement (filler), fine and coarse aggregate (binder), and water. With the characteristics of these materials, concrete’s type of bond attributes to its high thermal insulation properties and the strength of the material itself. Concrete is used for building materials and due to its thermal insulation properties as insulators. Mortar is a mixture of cementitious materials, water, and aggregate. For commercial use in buildings and constructions, it is useful by having water retentivity and its strength after stiffening and hardening. In addition, the content in the mortar of cement as well as air content affects the strength of the tensile bond between the mortar and the masonry. Due to the materials that compose mortar, it developed a chemical structure that is similar to its components. Also, in daily use, mortar is used for construction for buildings to attach segments together. To further investigate the properties of inorganic materials, I will continue with the properties of glass. Glass is composed of formers (usually silica SiO2 ), fluxes (frequently as a carbonate substa... ... middle of paper ... ...s in these structures are covalently bonded. Many types of fullerenes are arranged in large groups (many dozens of carbon atoms). Types of fullerenes discovered include C60 and C70. They can be used in products such as carbon nanotubes which in turn are used for electronic wires, science materials, and computer memory. Through researching both organic and inorganic materials, I have come to understand that there are many properties and structures ranging from shape to uses in commercial products. The advancement of science as well as technology is an underlying theme of this report which points to the development of future innovations. These innovations have at times been discovered accidently but the further movement of studies is a testament to the human desire for discovery. Further studies will exhibit more data and discoveries that will improve the world.

  • Comparing The Crystal Structures And Crystal Chemistry Of Fepo4 And Fepo4

    1009 Words  | 3 Pages

    Quartz (SiO2) is the second most abundant mineral on Earth and is of significant uses in both material and Earth sciences. Quartz crystals exist in polymorphs, which mean that the crystal structure of quartz will change depending on the temperature and pressure of the environment that the crystal is in. The crystal will be in its alpha-crystal form when the surrounding temperature and pressure is low. However, when exposed to intense temperature and pressure, it will convert to its beta-crystal form. This paper aims to look at the transition phase of the two different crystal structures using FePO4, a homeotype of quartz. Both quartz and FePO4

  • Melting Glass Essay

    1105 Words  | 3 Pages

    To understand the state of glass we must first have an understanding of the different states of matter. All matter is composed into states, and may move through these four existing states. The solid state is where the atoms of a substance are closely pact together with the only movement being the vibration of the atoms. The liquid state is where atoms are placed together in no order with a definite volume, but may move past each other giving it no definite shape. According to Science Magazine’s article in 1926 , glass exhibits traits from both of these states. It is similar to a liquid in that its atoms are randomly arranged, yet it has the fixed rigid bonding of a solid as well as the same high heat capacity(Science). This article in Science Magazine is a bit dated though and science changes drastically through years, especial...

    There are numerous factors that determine the durability of a concrete. However, the main factor is the time needed to keep the concrete in a saturation state. Moreover, the reason a concrete normally undergoes early age shrinkage is that the concrete is being allowed to dry out too quickly. Figure 1 below shows an experimental result that is carried out to compare the strength of concrete by using different types of surfaces for 180 days. The surfaces are such as: -

    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.

  • Mortars Of Refractory Mortar

    1137 Words  | 3 Pages

    Mortars consist of finely ground refractory materials which are then mixed with water to form a paste. They are used for laying and bonding shaped refractory products such as bricks. They are normally applied by trowelling [2]. The term Mortar is used to indicate a paste prepared by adding required quantity of water to a mixture of binding material like cement or lime and fine aggregates like sand. The above two components of mortar, namely, the binding material and fine aggregate are sometimes referred to as the matrix and adulterant respectively. The matrix binds the particles of the adulterant and as such, the durability, quality and strength of mortar will mainly depend on the quality and quantity of the matrix. The combined effect of the two components of mortar is that the mass is able to bind the bricks or stones firmly [1-2].

    Nowadays, the basic construction material is concrete which is used more than any other man-made material in the world to make pavements, architectural structures, foundations, roads, bridges, etc. Concrete is a construction material composed of cement (commonly Portland cement) as well as other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate such as gravel, limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures (such as accelerating admixtures, air-entraining admixtures, water-reducing and set-controlling admixtures, finely divided admixtures, polymers for polymer-modified concrete, superplasticizers, silica-fume admixture for high-strength concrete, corrosion inhibitors, etc). Concrete solidifies and hardens after mixing with water and placement due to a chemical process known as hydration. The water reacts with the cementitious material, which bonds the other components together, eventually creating a stone-like material.

    Sol gel method is a chemical synthesis technique for preparing gels, glasses, and ceramic powders because with the colloidal suspension-gel method we can manage to get up fine particles, control the uniformity of particle shape, control the final form of the sample, improve the particle size distribution, or develop low temperature routes [21] shown in figure 2 below. On the other hand, this process reaction are much more rapid and the degree of functionalization of the material can be kept in line [49]. The sol-gel process involves the use of metal alkoxides, which undergo hydrolysis and condensation polymerization reactions to give gels or aerogels with addition of acid as a catalyst which influence the gelation process of the solution [50].
