It is a non-crystalline solid or viscous material derived from petroleum, by natural or refinery process and substantially soluble in carbon disulfide. It is asphalt in a solid state and mineral tar in a semi-fluid state. Bitumen is brown or black in color. Bitumen is the binding material that is present in asphalt. It is […]

A pavement can be defined as a resistant surface that has been made with durable materials and whose construction objective is to allow the transport of vehicles, people and animals. Physically and mechanically a pavement has the objective of distributing the loads applied to the ground through the use of different layers and that does

Silica is a chemical compound known as silicon dioxide and is basically a natural compound that is formed from the combination of silicon and oxygen in a chemical formula of (SiO2) as a tetrahedral structure. Silica is the most abundant chemical compound in the earth’s crust because it forms part of the silicate group minerals

Portland cement is a tightly controlled chemical combination of calcium, silicon, aluminum, iron, and small amounts of other compounds, to which gypsum is added in the final grinding process to regulate the setting time of the concrete. Some of the raw materials used to make portland cement are limestone, shells, and gypsum or marl, combined

Unique types of cements for desired performance in a given environment are being manufactured by changing the chemical composition of the OPC or by using additives, or by using different raw materials. Some of the types of cements available in the market are the following: Fast-hardening Portland cement (IS:8041) This type of cement has a

Thanks to its good properties, mild steel has now become a widely used material in various construction and automation industries. It stands out because it has unmatched weldability and machinability, and in fact its applications are increasing. This article describes the importance, its uses, its advantages, and how this metal is made. What is mild

Fly ash or pulverized fuel ash (PFA) is the residue from pulverized coal combustion collected by mechanical or electrostatic flue gas separators or power plants. It constitutes about 75 percent of the total ash produced. Characteristics and composition The properties and composition of the Fly ash they vary widely, not only between different plants but

In general, asphalt is a very viscous hydrocarbon, which occurs in a dark brown to black color, and is produced from the distillation of petroleum. This distillation process can occur naturally, resulting in lakes of asphalt, or it can also occur at an oil refinery that uses crude oil. Its importance lies in the fact

Did you know that our world basically depends on lime? Limestone products are in greater demand today than ever before in history, and products and tools made from these building materials date back far into antiquity. At present practically all civil engineering and architecture structures are made in some way with lime, therefore this material

Abrasive materials are hard, rigid materials used to grind, sand, or polish other softer materials. They are an essential tool in many manufacturing processes and are used in various industries, including metalworking, construction, and automotive. There are many different abrasive materials, each with unique properties and characteristics. This article will explore the different abrasive materials types,
