Minerals, Rocks and Stones used in Construction
Rocks normally consist of several minerals, some essential, some accessory. A rock may be thought of as a "mineral environment." Each rock type was formed under certain specific conditions, resulting in the formation of a fairly predictable group of minerals. Rocks fall into three classes according to their origin: Igneous, Sedimentary, Metamorphic. Following are some rocks
Applications of Bitumen in Civil Engineering
The term bituminous materials is generally used to denote substances in which bitumen is present or from which it can be derived. Bitumen is defined as an amorphous, black or dark-colored, (solid, semi-solid, or viscous) cementitious substance, composed principally of high molecular weight hydrocarbons, and soluble in carbon disulfide. This article presents the
Characteristics of Good Paints
The vinyl paints are ideal for items that get repainted every few years. It does not last quite as long. There is some new paint that goes on almost twice as thick as normal paint. They come with a lifetime warranty against peeling and blistering. Following are some of the characteristics of good paints:Composition of Paints
Paints are used to protect metals, timber, or plastered surfaces from the corrosive effects of weather, heat, moisture or gases etc and to improve their appearance. Fundamental components of an oil-based paint are:
Classification and Methods of Sawing Timber
Classification of timber: Wood suitable for building or other engineering works is called timber When it forms a part of a living tree, it is called standing timber When the tree has been felled, it is called rough timber When it has been sawn to various market forms such as beams, battens, planks etc, it is called converted timberEffect of Liquids on Strength of Cement
The project's goal was to see how different liquids other than water affect the strength of cement. The object of this project was to find out how to make stronger cement which might help buildings better survive earthquakes.
Factors Affecting Selection of Construction Materials
Any material used for a construction purpose in the form of solid, semi-solid or liquid, processed or unprocessed (raw material) is known as construction material. A material engineer must be familiar with a wide range of materials used in a wide range of structures and is responsible for the following jobs with certain limits of compromises to be made on site.
Role of Materials in Construction | FUNCTIONAL REQUIREMENTS OF BUILDINGS
Material has major role in the creation of anything which makes it comfortable, durable, valuable, precious and beautiful. According to ancient scholars myth everything in universe has been made of four elements i.e. Air, Fire, Soil and Water. Here we will talk about the role of material in construction of buildings and buildings requirements. In the construction of any building there
Rubbers and Glass as Engineering Materials
It is present as an emulsion in the latex of rubber trees mostly grow in hot, moist climate ► Malaysia, Venezuela, Mexico. Latex is milky fluid oozing (dropping) from vertical grooves having an upward inclination cut around the trunk of the rubber tree. Pots are tied to the trunk of the trees for collecting latex. Crude rubber is obtained by coagulation of latex with alcohol, alum
Classification of Glass based on Composition & Applications
Glass is usually classified into three main classes: Soda Lime, Lead, Boro-Silicate glass and commercial forms of glass include: sheet glass, plate glass, tempered plate glass, laminated glass, wired glass, insulating glass, colored glass and flint glass. Flint Glass: It is lead glass which shines Used for glass work as optical glass, for making electric bulbs.
