Powder Form Set Accelerating

A powdered concrete accelerator (PSA™ code) is a convenient and readily usable product that effectively speeds up the setting time of concrete. This specific concrete admixture comes in a powdered form, making it particularly suitable for cold regions requiring accelerated hydration. Significantly, the addition of PSATM remains the same as the final strength of the concrete. Accelerator formulations typically consist of synthetic compounds derived from waste materials and residues. These compounds can be single substances or a combination of multiple substances. Most accelerators are categorized as organic or inorganic compounds, some containing chlorine and others chlorine-free. Various types of quick-setting additives influence the setting and hardening processes of concrete. For achieving rapid hardening and significant strength, recommended mixtures include triethanol and calcium formats, as well as blends of thiocyanates, thiosulfates, nitrates, alkaline amines soluble in water, metal aluminates, hydroxides, carbonates, ethanolamine, aluminates, alkali metal aluminates, and metal tetraborates. Furthermore, using potassium-based salts such as pyrophosphate, aluminate, and potassium carbonate has proven effective in achieving exceptional resistance.

PRODUCT DESCRIPTION

Introducing PSA™ Concrete Additive, a highly effective solution for reducing the setting time of concrete in various applications. Whether working in cold regions or requiring quick mold opening, PSA™ is the ideal product for accelerating the concrete setting process.
This ready-to-use additive comes in a convenient powder form, making it easy to incorporate into your concrete mixture. By increasing the hydration speed of the concrete, PSA™ significantly reduces the setting time without compromising the quality or strength of the final product.
With PSA™ Concrete Additive, you can confidently meet your project timelines while maintaining the highest standards of concrete performance. Our product is carefully formulated to comply with the ASTM C494 standard, ensuring reliable and consistent results.

    Frequently Asked Questions

    What is the best and most well-known concrete quick-setting additive?

    So far, the most well-known and widely used accelerator is calcium chloride. Many other materials have been found to accelerate the strength of concrete but are generally rarely used.

    What is the use of precipitators in concrete?

    Accelerators speed up the setting of concrete, which is also known as increasing the rate of hydration. This admixture may allow the concrete worker to remove forms sooner, walk on the concrete surface sooner, and sometimes even load it sooner.

    Are quick-setting agents suitable for cold weather concreting?

    Yes, one of the main applications of quick-setting concrete is working in cold climates, because there is a risk of freezing in cold weather, a method must be used that allows the concrete to set in the shortest possible time.

    What is the required standard for using concrete accelerator?

    Afzir's PSA TM concrete accelerator complies with ASTM C494 standard.

    Is concrete accelerator suitable for sprayed concrete?

    Yes, 100%, because sprayed concrete is mostly used for vertical surfaces and on vertical surfaces, we need quick setting of concrete to prevent the concrete from falling, we use quick setting agents.
