Number #1 Best Selling Concrete Accelerator
Calcium formate is a widely used as concrete admixture accelerator, especially in cold climates. It’s also known as calcium diformate, a type of calcium salt of formic acid. In winter concrete curing process, it’s your must-have accelerating admixtures.
Yuanwang Group is your reliable calcium formate manufacturer. We have been serving the construction sector with exceptional products and services.
Calcium formate concrete accelerators major benefits:
1. Frost protection. Prevent ice formation within the concrete mixture.
2. Set Accelerator. Speed up concrete curing before it gets frozen.
3. Reduce concrete setting time. Helpful in a wide range of cold temperatures.
4. Accelerates cement hydration. Results in quick strengthening.

Reducing Concrete Setting Time by 60 minutes!
Typically, the initial setting time of concrete is around 30 to 90 minutes.
When added concrete accelerator calcium formate, it makes a big impact. It greatly reduces the setting time. Depending on the conditions and dosage, calcium formate can shorten the setting time to just 10-30 minutes!
*The exact setting also depends on the curing areas. A bigger area requires a longer time to cure and set.

Fun Fact about Calcium Formate Concrete Accelerator
Calcium formate is a super versatile additive that can be used in both dry mix mortar and concrete!
When added to dry mix mortar, it’s before water. Mix all the dry ingredients first and then add water. Conversely, when added to concrete, it’s after water. In other words, calcium formate is added to the wet concrete mixture before use.

In concrete, an accelerator is a type of admixture (concrete accelerator admixture/accelerating concrete admixture) that is used to speed up the hydration process of cement, thereby increasing the early – strength development of concrete.
Unlike a retarder in concrete which slows down the setting time, an accelerator has the opposite effect. It shortens the setting time and accelerates the hardening of concrete. This is particularly beneficial in certain situations. For example, in cold – weather concreting, accelerators can help the concrete to set and gain strength more quickly, preventing it from being damaged by freezing.
Concrete accelerators are commonly made from calcium chloride, calcium formate or nitrates to prevent corrosion in reinforced concrete.
Concrete accelerator admixtures have significant advantages for construction projects. These additives speed up the curing process, which is especially helpful in cold weather when concrete normally hardens slowly. They also prove valuable in time-sensitive projects where fast construction is needed.
The accelerated setting time allows workers to remove formwork sooner than usual. This early strength development means construction can progress faster. Projects are completed in less time, reducing labor costs and minimizing delays.
Additionally, these admixtures are particularly useful for road repairs and precast concrete production. In both cases, the faster curing time translates to quicker project completion. The result is improved efficiency and lower overall costs.
✅ Increased Productivity: Faster construction cycles due to reduced curing time.
✅ Improved Durability: Early strength gain reduces the risk of frost damage in cold climates.
✅ Versatility: Can be used in shotcrete, precast concrete, and emergency repairs.
For calcium formate-based accelerators, the typical amount used is about 0.5%–1.0% of the total weight of cement mortar or concrete, with a maximum recommended amount of no more than 2.5%. In winter, the dosage is usually increased slightly as the temperature drops. In summer, using just 0.3%–0.5% can still significantly boost early strength.
However, if you add too much accelerator, it can cause the concrete to set too quickly — even instantly — which might lead to cracking in plaster or mortar later on and can also reduce the final strength.
Yes, calcium chloride is a very common accelerator for concrete. However, it has a major downside: it can cause corrosion of steel reinforcement. Because of this, both in China and internationally, there has been a move towards non-chloride accelerators.
Calcium formate is a newer type of concrete accelerator. It can speed up cement hydration, boost early strength, and won’t corrode steel. Plus, calcium formate is environmentally friendly, so it’s widely used in oilfield drilling and cementing operations too.
1️⃣ Some ingredients in accelerators chemically react with minerals in the cement. The reaction products form more bonds between cement particles, speeding up the hydration process.
2️⃣ Faster hydration reactions release more heat. This raises the internal temperature of the concrete, helping it continue to hydrate even in cold conditions, preventing freezing and ensuring that early strength develops properly.

Yuanwang is experienced in managing large-volume orders for all grades of calcium formate products. However, we also handle small orders. The MOQ is 1 MT.
Yes, absolutely! Yuanwang has been practicing OEM support for many years. As it is an important part of brand awareness. We can design the layout of all relevant information outside the packaging to make it look more presentable and attractive!
Normally, we’ll share all the relevant info during consultation. Our experienced sales team understand the most recent shipping protocols. You may tell us your concerns, we’re always here to support!
Our calcium formate powder comes with standard Kraft paper bag packaging.
raft paperbag has several benefits, that’s why we chose it for calcium formate products.
The Kraft paperbag is strong and doesn’t tear easily, keeping the calcium formate powder safe during transportation. It’s also moisture-resistant, keeping the calcium formate dry and effective.
Last but not least, Kraft bags are eco-friendly. They’re made from trees or other plants, so they break down naturally. You can recycle these bags to reduce waste.
