ielts task 1 process- cement and concrete production. below is a sample band 9 answer to a process task 1 question on concrete production. source: cambridge english ielts past papers. question – the diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.
Manufacturing of cement involves various raw materials and processes. each process is explained chemical reactions for manufacture of portland cement. cement is a greenish grey colored powder, made of calcined mixtures of clay and limestone. when mixed with water becomes a hard and strong building material.
Stage of cement manufacture. there are six main stages of cement manufacturing process. stage 1 raw material extraction/quarry. the raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. the ore rocks are quarried and crushed to smaller pieces of about 6 inches.
since concrete waits for no one, the right tools can make the difference between a successful pour and a potential disaster. most of the essential tools are basic and do not require a significant investment. owning these eliminates the cost of rental fees and the lost time picking up and returning the equipment. some specialty equipment is more .
the type of concrete in which steel fibers 10 to 20 microns in diameter and 10 to 50 mm in length is used. fiber increases resilience, tensile strength, flexibility, and other qualities. the fibers may be of different materials like steel, polymer, glass, carbon, or even natural fibers like coconut fiber.
the remaining cement is shipped in bulk quantities by mean of trucks, rails or ships. cement manufacturing process flow chart. after explaining the complete process of cement making, flow chart would be like that. flow chart present the summary of whole process as shown below.
2.2 cement making cement clinker is manufactured by heating the blended and ground raw material (typically limestone and clay or shale and other materials) to partial fusion. the clinker burning takes place at a temperature of 1450 c in kilns, which are normally inclined rotating cylinders lined with heat-resistant bricks.
cement rotary kiln, cement manufacturing process, chemical rotary kiln, feed-processing equipment, dressing equipment, sand making company introduction henan hongtong machinery technology development co. ltd is one of chinese specialized enterprise in making building materials and machinery with experience more than 30 years.
Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. these ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.
Plan, source, make, deliver and return. in summary, the cement industry planning process is centralized and optimization oriented. there is no constraint in the availability of cement main raw materials with the exception of some countries where subsoil ownership regulations applied. cement manufacturing is capital and energy intensive where.
Minerals of natural origin as well as industrial products/by-products can be used for cement production as long as the main components of cement (cao, sio2,al2o3,fe2o3)are present in a required proportion on mixing and the impurities or undesirable components like alkalies, sulfur, chlorides, mgo etc are below the allowable levels to ensure cement quality and operational .
The diagrams below show the stages and equipment used in the cement making process, and how cement is used to produce concrete for building purposes. summarise the information by selecting and reporting the main features, and make comparisons where relevant. answer: read more stages and equipment used in the cement-making process .
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. a limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.
after that, after passing through the mixer, the powder is entered the rotating heater machine with a view to increasing the temperature of the powder stew. after which, in the next stage, the powder is crushed into the grinder and .
overall, there are various steps in both procedures, starting from mixing limestone and clay, and culminating in the concrete production with the help of a mixer. in the first stage, limestone and clay are crushed together in a crusher in order to form a powder. secondly, the powder is put inside a mixer and then, it ends up in a rotating heater. while the powder is .
Strength. together they constitute 70 to 80 per cent of cement. the average c3s content in modern cement is about 45 per cent and that of c2s is about 25 per cent. the calculated quantity of the compounds in cement varies greatly even for a relatively small change in the oxide composition of the raw materials. to manufacture a cement of stipulated.
Cement kiln. cement rotary kiln is the main equipment of calcining the cement clinker. the characteristics of a rotary kiln are simple structure, convenient and reliable control of the producing process.

The main features of these cement ingredients along with their functions and usefulness or harmfulness are given below: lime: lime is calcium oxide or calcium hydroxide. the presence of lime in a sufficient quantity is required to form silicates and aluminates of calcium. deficiency in lime reduces the strength of property to the cement.
Intensive production of new equipment has gradually replaced the backward mode, and industrial technology has developed rapidly. up to now, there are nearly 700 cement enterprises and countless cement plants of various sizes are engaged in the manufacturing of cement equipment and cement in the world. cement production is a complex process.
cement is a broad term for several types of materials with adhesive properties. most people are familiar with the cement used in concrete, but other types of cement are used as mortar, on pvc pipes, or for flexible items like types of cement are often confused with concrete, but this type of cement is in fact a component of concrete, the .
there are mainly five steps involved in the production of cement. first, limestone and clay are crushed together between two rollers of a crusher to produce a powder. after that, this powder is thoroughly mixed in a mixer and then the mixture is heated by passing through a rotating heater. heat is applied from the other end of the heater.
the diagram below shows the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes. summarise the information by selecting and reporting the main features and make comparisons where relevant. you should write at least 150 words.
