 — Anti-washout admixtures. Anti-washout admixtures concrete offers superior performance when the concrete is in a fresh state. By adding an anti-washout admixture to concrete and its viscosity is increased, There are a variety of types of anti-washout admixtures, such as those based on the cellulose system and the acrylic system.

Accelerators are a set accelerating admixture specially formulated to reduce setting time and increase the early strength of concrete. Reduction of form stripping time. Accelerators are suitable for the following: Pre-cast concrete; Early strength concrete; Road re-blocking requiring 24–hr curing time or shorter Ready-mix or Jobsite mix concrete

 — Compared to plain concrete (without accelerators), the 28-day strength can be significantly reduced (values typically in the range 20-50%). This effect becomes more significant with increased dosage. ... New York, pp. 127-136. 12. WHD Microanalysis Consultants Ltd. Long term dura- bility of concrete incorporating a new admixture: A …

Since the publication of the first edition ten years ago, significant developments have occurred in the use of admixtures in concrete. Eight new chapters and a full update of the preceding ten chapters bring this book up to date; reflecting the relative advances made in the science and technology of different groups of admixtures.

The effectiveness of various concrete admixtures in inhibiting the capillary flow of water and the flow of water under pressure is considered. The types of admixtures included in the discussion are accelerators, soaps, butyl stearate, finely subdivided dry materials, mineral oil, workability agents, and a miscellaneous group of proprietary com ...

 — Cold weather concrete has superior properties to concrete placed in hot weather. At low temperatures, though, concrete sets and gains strength more slowly because the cement doesn't hydrate as fast. Setting time is increased about one-third for each 10 degree decrease in concrete temperature down to 40 degrees Fahrenheit. …

 — Accelerating admixtures affect th e rates of reactions between cement and water to give an overall. increase in the hydration rate. Thus, the use of accelerators in …

 — Accelerators, both for normal concrete and for shotcrete, are widely used in modern construction because they can shorten the setting time and/or increase the early …

 — Admixtures are liquids or powders added in concrete, based on mix design computations, with an objective to improve the fresh as well as enhance the hardened state properties of concrete.

Why Choose Fritz-Pak's Concrete Set Accelerator? Speeds up concrete set-time; Provides higher early strength; NCA does not promote steel corrosion; ... Fritz-Pak NCA is compatible with most concrete admixtures. When used with other admixtures, each one should be dispensed separately into the mix. Effectiveness of NCA is dependent on the ...
