What is a concrete release agent?

A concrete release agent is a compound applied to the building design prior to the concrete is poured so that the template doesn’t stick to to the concrete surface following pouring, isn’t simple to take apart the form or impacts the finish of the concrete covering. Its principal role inside the design and the concrete covering to create a film that is going to be separated from the two is also known as an separation agent.

A water-based release agent is surely an crucial auxiliary in the release agent and can change the water-based release agent flow and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based mould release agent can be used in forms and products functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items are not only so as to let the form release to enhance productivity and extend the life of the form make use of. And can make the merchandise clear, size qualified, and reduce the generation of scrap, which is an important additional essential to moulds and items – concrete additive.

Concrete release agent plays an important role in modern building construction; its principal role is to create a layer of isolation motion picture between the template and the concrete area in order that the template will not stick to the concrete surface in order that it is simpler to dismantle the mould following flowing and to maintain the complete of the concrete area. Here, we will unveil the types, qualities, use and application of concrete release agent in detail.

Types of concrete release agent

Concrete release brokers can be divided into many kinds in accordance with different classification methods, and the typical category strategies 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 release agent for tunnels and and so forth.
• According to the composition of: it can be divided into water-based concrete release agents, oil-based concrete release agents, silicone oil concrete release representatives, etc.
• According to the use effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release representatives, high-gloss concrete release agents and so on.

Features of Concrete release agent

A concrete release agent is additionally known 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 role of lubrication and remoteness to ensure that the concrete could be easily detached from the formwork when dismantling the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low value and and so forth. However, not all types 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 important construction auxiliary material, concrete release agent has the subsequent qualities:
Good remoteness performance: concrete release agent can form a dense remoteness movie between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete covering and facilitating the removing.

Great lubrication performance: concrete release agent has good lubrication performance, which can decrease the friction between the formwork and concrete surface, lower the resistance during pouring and improve the construction effectiveness.

Great anti-adhesion efficiency: concrete release brokers can effectively avoid the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete area when dismantling the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can successfully avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing the service life of the formwork.

Simple 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 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 covering.

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 area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the dismantling.

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 development projects, mainly including the following aspects:

Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing 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 surface, 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 covering 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 agents 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 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.
