MoreDuring placement, the concrete is consolidated to compact it within the forms and to eliminate potential flaws, such as honeycombs and air pockets. For slabs, concrete is left to stand until the surface moisture film disappears, then a wood or metal handfloat is used to smooth off the concrete. Floating produces a relatively even, but slightly rough, texture that has good slip

More22.07.2020 Cement is one of the four raw materials that are used in the production of concrete, along with gravel, sand and water. To be exact, concrete consists of 50% gravel, 25% sand, 15% cement and 10% water. All four materials are blended together in a rotating machine called a concrete mixer.
More11.06.2020 A process called Rubberization can be achieved through recycled concrete. In this process, the pavement concrete can be broken down in its own place and used as a base layer for the new pavement. Larger pieces of crushed recycled concrete can be used for Riprap revetments, which are a very effective and popular method of controlling erosion.

MoreThis process is simpler than cement production; concrete is a mixture of 15% cement, 10 % water, 25% sand and 50 % small stones which are named as “Gravel”. The four elements are poured in a huge mixer which rotates producing concrete. We can see that once the cement is produced by several steps and equipment, it can be used in other less complicated

(157 Words, 10 Sentences, 4 Paragraphs, Band 9) The first diagram illustrates the process of cement manufacture, and the second diagram shows the materials that go into the production of
More29.04.2019 Sample answer 2:-. The diagrams show the process and the equipment used to make cement and, how these are used to produce concrete for building purposes. The first step in cement production is to introduce limestone and clay. These materials pass through a crusher that produces a powder then, this powder goes into a mixture.
MoreYou should write at least 150 words. The given diagrams show the cement making process and the type of equipments and materials used to produce the cement. It also shows how the cement is used to produce concrete. According to the first pictorial, cement production is a complex process that involves lots of materials and numerous steps.
MoreThe curing of concrete by CO 2 is only sustainable if the carbon used for the process is recycled. The use of newly produced CO 2 for this process won’t make this a sustainable practice. The method is sustainable when the CO 2 emitted from industries and manufacturing processes are collected, treated, and used for curing concrete.
MoreThe 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. The two processes are essentially alike except in the wet process, the raw materials are ground with water before
More16.06.2016 The frame also guides the precise placement of reinforcement materials used to strengthen the concrete. Your team will start the project by building the forms for the footings and create the remaining structure using that foundational guide. Concrete Placement; Depending on your project scope, you may need to call in the concrete pouring company several times
More11.06.2020 Recycled concrete can be used as an efficient building material, if it is crushed properly and kept free of unwanted materials and contaminants. A process called Rubberization can be achieved through recycled concrete. In this process, the pavement concrete can be broken down in its own place and used as a base layer for the new pavement. Larger pieces
MoreThe shotcrete process requires less formwork and can be more economical than conventionally placed concrete. Shotcrete is applied using a wet- or dry-mix process. The wet-mix shotcrete process mixes all ingredients, including water, before introduction into the delivery hose. The dry-mix shotcrete process adds water to the mix at the nozzle. Shotcrete is used in new
