Production of concrete SlideShare

09/04/2017· Compaction of concrete: • Compaction of concrete is process adopted for expelling the entrapped air from the concrete • In the process of mixing , transporting and placing of concrete air is likely to get entrapped in the concrete . • It has been found from the experimental studies that 1% air in the concrete approximately reduces the strength by 6%. • If we don’t expel this air, it

Environmental impact of concrete Wikipedia

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 Cement Is Made

Portland cement is the basic ingredient of concrete. 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 and Sustainability

There is currently a high degree of investment in producing new technologies that reduce the impact of cement production including, for example, one that uses relatively large quantities of CO2 in the production process. Projecting the sustainability-related performance benefits of concrete

Energy Consumption in Production of Concrete

28/08/2017· The production of 1 m³ of concrete requires 2,775 MJ of energy. This energy comes mostly from oil burning, which generates CO2. 2.775 MJ of energy is produced by 0.37 barrels of oil. Saving concrete, e.g. by adopting appropriate building solutions, means therefore not only reducing fossil fuels consumption, but also pollutant emissions.

The Environmental Impacts of Concrete

• Important to realise is that although 5% of the worldwide generation of CO 2 is due to cement production, that level of output also reflects the unique and universal importance of concrete throughout the construction industry.

How concrete block is made material, manufacture, used

Today, concrete block manufacturing is a highly automated process that can produce up to 2,000 blocks per hour. Raw Materials The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A

23 Types of Concrete Used in Construction and their

The production of polymer concrete will help in the reduction of volume of voids in the aggregate. This will hence reduce the amount of polymer that is necessary to bind the aggregates used. Hence the aggregates are graded and mixed accordingly to achieve minimum voids hence maximum density. This type of concrete has different categories:
