Admixtures are manufactured or natural chemicals mixed combined with concrete during or before mixing. They provide some special properties to both fresh and hardened concrete and can improve workability, strength, and/or durability of concrete mixture. Some of the major types of these admixtures are air-entraining agents, waterproofing agents, water reducing agents, retarding agents, and accelerating agents.
Concrete admixtures can benefit concrete in many ways:
• Enhancing concrete work ability
• Increasing concrete resistance against freeze-thaw effect
• Acting as an anti-bacterial agent
• Improving sustainability by bringing waste products in use
• Controlling alkali-aggregation expansion
• Reducing segregation in grout mixtures
• Producing colored mortar or concrete
New Admixture for Control Flow Concrete
The demand for and use of concrete admixtures is increasing rapidly; thus, major manufacturers are expanding their global presence and focusing on developing high-end technologies and products to sustain intense competition. GCP Applied Technologies, Inc. recently launched Concera concrete admixtures, which allow the production of control flow concrete—a new category of segregation-resistant, highly flowing concrete with common mix designs. This type of concrete is ideal for use in walls, columns, decks, beams, footers, and floors. With Concera admixture, manufacturers can produce highly consistent concrete with excellent flow maintenance without retardation.
Market Overview
According to the findings of a research report by Grand View Research, Inc., the global concrete admixtures market is anticipated to register a healthy CAGR of around 7 % over the forecast period (from 2017 to 2025). This growth is supported by rising investments in the infrastructure and hospitality sectors across the globe. In addition, shifting preference of population toward urbanization is projected to augment the growth of the global market over the next few years.
Some of the prominent companies operating in the worldwide market are RPM International Inc.; MAPEI S.P.A.; BASF SE; The Dow Chemical Company; Pidilite Industries Ltd.; Chryso S.A.S.; and Sika AG. Global business expansion, product development, and mergers and acquisitions are some of the key strategies followed by these companies to attract more consumers and maintain their market position.
