Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content.
Concrete admixtures are essential components used to enhance the properties of concrete mixes. This guide provides valuable insights into various types of concrete admixtures, their characteristics, European standards and applications.
When OPC is mixed with water, sand, and gravel material during the production of concrete, it becomes highly alkaline, creating a seemingly ideal environment for the sequestration and long-term storage of carbon dioxide in the form of carbonate materials (a process known as carbonation).
'Green-mix' concrete. Permeable Concrete that absorbs 4 Liters of Water per Minute. Recently developed Topmix permeable concrete is recommended by the EPA, other agencies and geotechnical engineers allows for the more efficient use of land by rendering retention ponds, swales and other stormwater structures obsolete.
The annual concrete production in the world is quite high and it is estimated that the average concrete production per human per year is around one ton (Lippiatt and Ahmad, 2004). Cement, is one of the main components of concrete and around 10–12% by volume of concrete is occupied by cement (Van Oss and Padovani, 2002). The superior ...
