What exactly is a concrete release agent?

A concrete release agent is a compound placed on the building template just before the concrete is added so that the template will not adhere to the concrete area after putting, is just not simple to take down the cast or impacts the end of the concrete surface. Its main role inside the template and the concrete surface to develop a movie that is going to be separated from the two is additionally known as an isolation agent.

A water-based release agent is surely an essential supplementary inside the release agent and can change the water-based release agent flow and levelling; its principal feature is stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based cast release agent is utilized in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast goods are not just to be able to let the form release to improve productivity and prolong the life of the mould make use of. And can make the item thoroughly clean, size qualified, and lower the creation of scrap, which is an important additive vital to casts and goods – Water-based Concrete Release Agent.

Concrete release agent plays an essential role within modern building building; its principal role is to create a layer of remoteness movie between the template and the concrete covering to ensure that the template will not stick to the concrete covering in order that it is simpler to take apart the cast after flowing and to maintain the complete of the concrete surface. Here, we will unveil the kinds, characteristics, use and application of concrete release agent in detail.

Kinds of concrete release agent

Concrete release representatives can be divided into numerous sorts based on different classification techniques, and the frequent category strategies are as follows:

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

Features of Concrete release agent

A concrete release agent is additionally called a concrete isolation agent or mould release lubricant. It is actually a type of compound coated on the inner wall of the formwork to play the function of lubrication and separation so that the concrete could be smoothly detached from the formwork when dismantling the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low cost and so on. However, not all types of concrete release brokers with a selection of components made of templates are suitable for different components of the template and different construction circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the following qualities:
Good separation overall performance: concrete release agent can form a dense remoteness movie between the formwork and the concrete surface, effectively preventing the formwork from bonding with the concrete surface and facilitating the removing.

Good lubrication overall performance: concrete release agent has good lubrication performance, which can reduce the chaffing between the formwork and concrete surface, reduce the resistance during pouring and boost the construction efficiency.

Great anti-adhesion overall performance: concrete release representatives can successfully prevent the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete surface when taking apart the formwork.

Great waterproof efficiency: concrete release agent has good waterproof efficiency, which can successfully stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing the service life of the formwork.

Effortless to use and safe: concrete release agent is easy 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 petroleum-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 surface.

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

Clean up the template: after dismantling 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 increasing 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 surface and boost 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 construction projects.

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