Oct 15, 2016· Energy consumption during production and construction (PAC) of buildings' frames is evaluated. • Production of materials/components consumed 90% of energy during PAC of buildings' frames. • Energy consumption during PAC of concrete frames is 27% less than steel frames of buildings. •
Future concrete deterioration of concrete structures may partially come from errors in concrete production, casting, pouring or placing, and compaction. For example, inadequate curing may result in the development of microcracks perpendicular to the concrete surface, owing to drying shrinkage.
Jul 26, 2016· Although concrete is a popular building material, many people are unfamiliar with concrete production, as well as how concrete is delivered and poured. If you're considering using concrete for a construction project, knowing more about how concrete works can help you choose the right mixture for your project.
Concrete block production | Masa Group. The manufacturing of autoclaved aerated concrete products demands high standards for mixing and dosing of the aggregates, the control of the fermentation process and the control of each production step.
Production of concrete. The properties of the end product depend not only on the various constituent materials listed above but also on the way they are proportioned and mixed, as well as on the methods of placing and curing the composite. Mix design. It is not possible to predict the strength
Aug 28, 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.
Sep 01, 2015· The materials required for the production of the concrete blocks are aggregates, cement and water. The aggregates of various types have been used with varying degree of success and they include crushed stones, gravel, volcanic cinders, foamed slag, furnace clinker, etc.

Fresh concrete Most excess fresh concrete comes from the washing of equipment, cut-outs, leftover in the buckets etc. The sand and gravel can be separated from fresh concrete and reused in the production of new concrete. The cement slurry left after the removal of the sand and gravel can be left in basins for evaporation.
The concrete slab production process is based on the compaction of concrete by means of hydraulic pressing. In this procedure, two concrete layers are filled into the Masa slab press successively and compacted in a mould. The result is a two-layer slab. The advantage of this method is that it gives concrete slab manufacturers great creative ...
