Optimizing Performance and Crack Control with Shrinkage-Reducing Concrete Additives

What exactly is a concrete release agent?

A concrete release agent is actually a substance put on the development design just before the concrete is added so the design does not stick to to the concrete surface after flowing, is not simple to take down the form or affects the complete of the concrete area. Its main role inside the template and the concrete area to develop a motion picture that is going to be separated from the two can also be called an remoteness agent.

A water-based release agent is definitely an essential ancillary in the release agent and can alter the water-based release agent circulation and levelling; its primary characteristic is stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based form release agent can be used in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing mould goods are not only in order to let the mould release to improve productivity and prolong the life of the form make use of. And can make the merchandise clean, size qualified, and lower the creation of scrap, which is an important supplementary important to moulds and goods – concrete release agent.

Concrete release agent plays an important role within modern building development; its main role would be to develop a layer of remoteness movie between the template and the concrete surface so that the design doesn’t adhere to the concrete covering in order that it is much easier to dismantle the form right after flowing and to maintain the end of the concrete covering. Here, we will introduce the types, features, utilization and application of concrete release agent at length.

Sorts of concrete release agent

Concrete release agents can be divided into several sorts in accordance with different grouping methods, and the typical grouping techniques are the following:

  • According to the the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete launch agent for tunnels and etc.
  • According to the composition of: it can be divided into water-based concrete release agents, petroleum-based concrete release agents, silicone oil concrete release agents, etc.
  • According to the the use effect: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release brokers, high-gloss concrete release brokers and so on.

Features of Concrete release agent

A concrete release agent can also be called a concrete isolation agent or mould release lubricant. It is actually a kind of material coated on the inner wall of the formwork to play the function of lubrication and isolation to ensure that the concrete could be easily detached from the formwork when taking apart the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and so on. However, not all sorts of concrete release representatives with a array of materials made of templates are suitable for different materials of the template and different construction circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the following features:
Good separation overall performance: concrete release agent can develop a dense separation film between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete area and facilitating the dismantling.

Good lubrication efficiency: concrete release agent has good lubricating efficiency, which can lower the friction between the formwork and concrete surface, lower the resistance during pouring and improve the construction efficiency.

Excellent anti-adhesion overall performance: concrete release brokers can successfully avoid the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete surface when taking apart the formwork.

Excellent waterproof performance: concrete release agent has good waterproof performance, which can successfully prevent moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.

Effortless to use and safe: concrete release agent is simple to use; you only need to apply a layer evenly on the formwork; at the same time, it is safe and environmentally friendly and will not pollute the human body and the environment.

When using a concrete release agent, the following steps should be followed:

Prepare tools: concrete release agent is usually sprayed or brushed for construction. You need to prepare construction tools such as a sprayer or brush.

Choose the right release agent: According to the different environments, choose the right concrete release agent, such as indoor use can choose a water-based concrete release agent, and outdoor use can choose an oil-based concrete release agent.

Apply the release agent: Pour the appropriate amount of release agent into the sprayer or container, and then evenly spray or brush on the formwork to ensure that each part is coated in place.

Air drying: After application, wait for a period of time to allow the release agent to dry naturally. Generally, it takes 10-20 minutes, depending on the environment.

Pouring concrete: After the release agent is completely air-dried, the concrete can be poured. During the pouring process, care should be taken to avoid air bubbles or voids between the formwork and the concrete area.

Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When dismantling the formwork, the connectors at the edge of the formwork should be dismantled first, and then the covering of the formwork should be knocked gently to separate the formwork from the concrete surface gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the taking down.

Clean up the template: after taking down the template, the template should be cleaned up to remove the residual concrete and mould release agent. After cleaning, it can be used for the next time.

Application areas of concrete release agent:

Concrete release agent is widely used in all kinds of building projects, mainly including the following aspects:

Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release agents can be used for formwork isolation, avoiding formwork from bonding with concrete and improving construction efficiency and quality.

Road construction: in road construction, the concrete release agent can be used to isolate the bond layer between the road formwork and concrete covering, to avoid road bubbles, hollow drums and other problems.

Bridge project: In a bridge project, a concrete release agent can be used to isolate the bond layer between the bridge formwork and the concrete area and improve the construction quality of the bridge pier and abutment.

Tunnelling project: In the tunnelling project, a concrete release agent can be used to isolate the bond layer between tunnel formwork and shotcrete surface to enhance the quality and safety of tunnel construction.

Nuclear power project: In nuclear power project, a concrete release agent can be used to isolate the bond layer between the shell of nuclear power equipment and internal components to ensure the safety and stability of the equipment.

Other fields: concrete release brokers can also be widely used in water conservancy projects, wharf projects, airport projects and other fields to provide effective formwork isolation protection measures for various development projects.

In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right type, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the building industry.
