What is the ratio of early strength antifreeze?

1. Concrete early strength agent ratio

1. Dosage: generally 3-6% of cement.

2. In order to maintain the uniform quality of the concrete mixed with this agent, the mixing time should be extended by 1-2 minutes.

3. Concrete (tong) mixed with this agent cannot be used in orthopedics with active minerals (such as opal).

4. If this agent is damp and agglomerated, it must be crushed or weathered before use. Its performance will remain unchanged.

2. Concept of retarded concrete

Concrete early strength agent is one of the concrete admixtures, which refers to admixtures that can increase the early strength of concrete and have no significant impact on the later strength. The main function of early strength agent is to accelerate the hydration rate of cement and promote the development of early strength of concrete; it has both early strength function and certain water reduction and enhancement function

Every m3 of concrete should be added How much early strength antifreeze?

3-6% early strength antifreeze of cement should be added to every m3 of concrete. Introduction: Concrete antifreeze early strength admixture refers to an admixture that can improve the early strength of concrete and has no significant impact on the later strength. The main function of early strength agent is to accelerate the hydration rate of cement and promote the development of early strength of concrete; it has both early strength function and certain water reduction and enhancement function. Concrete early strength agent is one of the earliest types of admixtures used in the history of admixture development. So far, people have developed a variety of early-strength additives other than chloride and sulfate, such as nitrite, chromate, etc., as well as organic early-strength additives, such as triethanolamine, calcium formate, urea, etc. On the basis of early-strength additives, a variety of composite admixtures are produced and applied, such as early-strength water-reducing admixtures, early-strength antifreeze and early-strength pumping agents. These types of early-strength admixtures have been used in actual projects and have played an important role in improving concrete properties, increasing construction efficiency and saving investment costs.

How much antifreeze and early strength agent should be added to a dry hard mortar?

One cubic meter of mortar

The amount of early strength agent required for one cubic meter of concrete is generally 3%-6% of the cement content in the concrete. The dosage of early-strength agent is calculated based on the dosage of concrete cementitious material multiplied by the dosage recommended by the manufacturer of the early-strength agent or the trial dosage. Early strength agent is one of the concrete admixtures. Concrete early strength additives refer to admixtures that can increase the early strength of concrete and have no significant impact on later strength.

How to use Sihai Huinong antifreeze?

The usage method is as follows: For construction at 0~ -5℃, 4~6% can be added. For construction at -5~ -10℃, 5~8% can be added at -10~ -15℃ Under construction conditions, 8~10% concrete antifreeze can be added. Early strength antifreeze uses special antifreeze materials, which can effectively reduce the freezing point of concrete and mortar and greatly improve the antifreeze performance of concrete and mortar at negative temperatures.

And it can increase the early strength of concrete and mortar by more than 80% without reducing the later strength, thereby ensuring that the strength is equally developed under positive and negative temperature conditions. The effect is remarkable.

How much mortar antifreeze is needed for one cubic meter of concrete?

1. For construction at 0~ -5℃, 4~6% can be added. 2. For construction at -5~-10℃, 5~8% can be added. 3. For construction at -10~-15℃, 8~10% can be added. Early-strength antifreeze uses special antifreeze materials, which can effectively reduce the freezing point of concrete and mortar, and greatly improve the antifreeze performance of concrete and mortar at negative temperatures. And it can increase the early strength of concrete and mortar by 80%...

When taking concrete anti-freeze measures, you can add alkaline water agent or air-entraining agent, which can make the anti-freeze effect better. , can also ensure that the concrete can achieve the desired effect. </p
