What is a concrete release agent?

A concrete release agent is definitely a compound put on the construction template prior to the concrete is added so the template will not stick to to the concrete covering after flowing, is just not effortless to dismantle the cast or impacts the complete of the concrete surface. Its principal role within the design and the concrete covering to develop a motion picture that will be separated from the two can also be called an isolation agent.

A water-based release agent is surely an essential supplementary inside the release agent and can modify the water-based release agent stream and levelling; its main characteristic is definitely stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based cast release agent is utilized in moulds and goods functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form items are not just so as to let the form release to improve productivity and prolong the life of the cast make use of. And can make the item clear, size qualified, and lower the generation of scrap, which can be an essential supplementary important to forms and goods – concrete release agent.

Concrete release agent plays an essential role inside modern building building; its primary role would be to create a layer of remoteness movie between the template and the concrete surface so that the template will not stick to the concrete area to ensure that it is much easier to dismantle the mould right after putting and to maintain the end of the concrete area. Here, we will introduce the kinds, qualities, usage and use of concrete release agent at length.

Kinds of concrete release agent

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

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

Qualities 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 kind of substance coated on the inner wall of the formwork to play the role of lubricating and remoteness in order that the concrete can 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 material motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low value and etc. However, not all types of concrete release brokers with a selection of supplies 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 suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next characteristics:
Good separation efficiency: concrete release agent can form a dense separation motion picture between the formwork and the concrete covering, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the demolding.

Great lubrication efficiency: concrete release agent has good lubricating efficiency, which can lower the chaffing between the formwork and concrete area, lower the resistance during pouring and improve the construction effectiveness.

Good anti-adhesion overall performance: concrete release representatives can efficiently prevent the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete covering when taking apart 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, avoiding deformation of the formwork by moisture and enhancing the service life of the formwork.

Simple 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 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 surface 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 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 construction projects, mainly including the following aspects:

Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding formwork from bonding with concrete and enhancing 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 surface 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 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 building projects.

In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern construction 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 construction project and provide a strong guarantee for the growth of the development industry.
