Concrete admixtures are chemical concoctions mixed in the right quantity with cement or concrete to obtain the design, functional and beautifying effect aimed for civil structures. These are used more and more today in residential, commercial, industrial and infrastructure ventures.
Admixtures offer various advantages such as strength, long life, color, protection against chemicals, lesser need for water and cement, and also improved working attributes of concrete, which can be chemical and mineral.
Chemical admixtures comprise normal plasticizers, super plasticizers, retarding and accelerating agents, air-entraining agents, waterproofing admixtures, corrosion retardants and coloring agents. Mineral admixtures comprise silica slag, fly ash and rice husk ash.
ReportsnReports’ report encompasses qualitative factors of mineral admixtures and comprehensive volume (kilotons) and value ($ million) prognosis of chemical admixtures according to types and location. Locations covered are Asia-Pacific, North America, South America, Middle East and Africa, and Europe. Applications comprise residential, industrial, commercial and infrastructure. The market is evaluated by investigating cement consumption trajectories, how it would help cement manufactures, and typical usage of admixtures by weight for different grades of concrete for different applications and locations. The price trajectories of the chemicals have been investigated from yearly reports of important participants.
Some factors recognized for concrete admixtures are enhanced quality of construction in developing countries, more demand for roads, bridges, buildings, tunnels and water holding structures, and lesser water usage and construction time. The market is somewhat hampered by rising prices and insufficient knowledge about admixtures by construction promoters, especially in the unorganized sector. Opportunities for growth are noted in increasing residential needs; more people opting to remodel and repair their homes; and quickly developing economics in the Asia-Pacific region.
