What is a concrete release agent?

A concrete release agent is actually a compound applied to the development template prior to the concrete is added in order that the template doesn’t stick to to the concrete area following pouring, is just not effortless to dismantle the mould or affects the finish of the concrete covering. Its main role inside the template and the concrete covering to form a motion picture that will be separated from the two is additionally known as an separation agent.

A water-based release agent is surely an essential ancillary inside the release agent and can change the water-based release agent circulation and levelling; its main characteristic is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is utilized in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form items aren’t just in order to let the mould release to enhance productivity and prolong the life of the mould use. And can make the merchandise clean, size qualified, and lower the creation of scrap, that is an essential additive important to moulds and products – Water-based Concrete Release Agent.

Concrete release agent plays an essential role inside modern building construction; its main role would be to form a layer of remoteness film between the design and the concrete surface to ensure that the template will not stick to the concrete covering so that it is simpler to take apart the cast following putting and to maintain the finish of the concrete surface. Here, we will unveil the sorts, characteristics, utilization and application of concrete release agent in detail.

Types of concrete release agent

Concrete release representatives can be divided into numerous kinds in accordance with different classification techniques, and the common category techniques are as follows:

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

Features of Concrete release agent

A concrete release agent can also be referred to as a concrete remoteness agent or mould release lubricant. It is really a type of material coated on the inner wall of the formwork to play the part of lubricating and isolation in order that the concrete can 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 traditional release material motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low value and so on. However, not all sorts of concrete release brokers with a selection of materials made of templates are suitable for different materials of the template and different development conditions and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the following qualities:
Good isolation overall performance: concrete release agent can create a dense isolation movie between the formwork and the concrete covering, successfully avoiding the formwork from bonding with the concrete surface and facilitating the demolding.

Good lubrication overall performance: concrete release agent has good lubrication performance, which can reduce the friction between the formwork and concrete covering, decrease the resistance during pouring and improve the construction productivity.

Excellent anti-adhesion overall performance: concrete release representatives can successfully stop the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete covering when taking down the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof efficiency, which can efficiently prevent moisture from penetrating between the formwork and concrete, avoiding 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 down 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 covering gradually. In case of tight bonding between the formwork and the concrete covering, tools can be used appropriately to assist in the dismantling.

Clean up the template: after taking apart 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 construction 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 area 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 boost 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 crucial construction auxiliary material, plays an indispensable role in modern construction 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 building project and provide a strong guarantee for the growth of the building industry.
