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.
the production of cement involves a 5 stage, linear process that begins with the mixing of raw materials and culminates in the packaging of new cement. making concrete is a simpler process that involves mixing four ingredients in a concrete mixer.
portland cement accounts for 95 percent of the hydraulic cement production in the united states. the balance of domestic cement production is primarily masonry cement. both of these materials are produced in portland cement manufacturing plants. a diagram of the process, which encompasses production of both portland and masonry cement, is shown .
cement manufacturing process phase ii: proportioning, blending & grinding. the raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. generally, limestone is 80% and remaining 20% is the clay.
Cement - cement - extraction and processing: raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. some deposits are mined by underground methods. softer rocks such as chalk and clay can be dug directly by excavators.
Cement is so fine that 1 pound of cement contains 150 billion grains. the cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. although the dry process is the most modern and popular way to manufacture cement, some kilns in the united states use a wet process.
Cement manufacturing: components of a cement plant. this page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant - the kiln, the cement mill etc.. for information on materials, including reactions in the kiln, see the ' clinker ' pages.
Cement production involves more steps as compared to the production of concrete but the former requires less number of raw materials than the latter. concrete is the final output which is directly used for the building process, whereas cement is a semi-finished product and needs further processing.
Cement production were estimated at 829 mmtco2 in 2000 7, approximately 3.4% of global co 2 emissions from fossil fuel combustion and cement production. in addition to combustion-related emissions, cement production also is a source of process-related emissions resulting from the release of co2 during the calcination of limestone.
Clinker is the main ingredient in cement, and the amount used is directly proportional to the co 2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker production process.. from 2014 to 2018, the clinker-to-cement ratio increased at an average of 1.6% per year, reaching an estimated 0.70 in 2018; this rise .
Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.
Concrete production is a highly intensive energy-consuming process and presently facing a number of challenges in reducing the carbon footprint and making it more economic. sustainable technologies in maintaining concrete structures are proving to be a great challenge.

cement emissions. the production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases co 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in co 2 emissions. the direct emissions of cement occur through a chemical process called calcination.

producing concrete blocks is not a very difficult job. there are different ways to produce them: manually with simple molds or with a machine. of course, the machine is more preferred because it helps to handle the job easier and faster. we will explain the concrete block manufacturing process details in this article.
laboratories of cement plants check every step in the manufacturing process of cement by frequent physical and chemical tests. labs also test and analyze the end product to ensure that it complies with all industry specifications. the most common way of manufacturing cement is a dry method. the foremost step is to quarry the primary raw .
Process the production of concrete blocks consists of four basic processes: mixing, molding, curing, and cubing. some manufacturing plants produce only concrete blocks, while others may produce a wide variety of precast concrete products including blocks, flat paver stones, and decorative landscaping pieces such as lawn edging.
cement manufacturing process. cement manufacturing process. cement is a material which is used to bind other materials together. binding means it has an effect of gluing the substances together due to cohesive and adhesive action and then hardens and sets in order to become permanent. cement is usually not used on its own; it is mixed with .
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.

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. the limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers .
