Concrete Production an overview ScienceDirect Topics

Requirements for the use of recycled materials in concrete production, as one of the most commonly used materials in construction, are becoming more common. Currently, a growing problem is the disposal of car tires. This chapter presents an overview of current expressions for the estimation of rubberized concrete compressive strength based on its constituents. Since rubber waste is a very

Concrete

Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens. In modern usage, most concrete production takes place in a large type of industrial facility called a concrete plant, or often a batch plant. In general usage, concrete plants come in two main types, ready mix plants and central mix plants. A ready-mix plant mixes all the ingredients except water, while a central mix plant mixes all the in

Environmental impact of concrete

The CO 2 emission from the concrete production is directly proportional to the cement content used in the concrete mix; 900 kg of CO 2 are emitted for the fabrication of every ton of cement, accounting for 88% of the emissions associated with the average concrete mix.

How Concrete is Made Portland Cement Association

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 resistance and is frequently used as a final finish for exterior slabs. If a smooth, hard, dense surface is required, floating is followed by steel troweling.

Ways to Recycle and Reuse Concrete

07/01/2019 Aggregate for mixing new concrete: Crushed concrete can replace some of the virgin (new) aggregate used in ready-mix concrete. Controlling streambank erosion: Larger pieces of crushed concrete placed along vulnerable stream banks or gullies can help control erosion. Landscaping mulch: When properly crushed and well sorted, ground concrete can replace river rock or other gravels used

The History of Concrete and Cement ThoughtCo

06/03/2019 In 1824, the English inventor Joseph Aspdin invented Portland Cement, which has remained the dominant form of cement used in concrete production. Aspdin created the first true artificial cement by burning ground limestone and clay together. The burning process changed the chemical properties of the materials and allowed Aspdin to create a stronger cement than plain
