What is actually a concrete release agent?

A concrete release agent is a substance placed on the development design just before the concrete is put so that the template will not stick to to the concrete covering right after putting, is just not easy to take apart the cast or impacts the complete of the concrete surface. Its main role within the template and the concrete area to create a motion picture that will probably be separated from the two is also called an isolation agent.

A water-based release agent is an crucial supplementary inside the release agent and can modify the water-based release agent stream and levelling; its principal characteristic is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based mould release agent can be used in moulds and items functional processing additives; in the rubber, plastic, and Jinsu processing business, manufacturing mould products aren’t just so as to let the cast release to enhance productivity and extend the life of the mould utilize. And can make the item clean, size qualified, and reduce the technology of scrap, which is an important additional important to moulds and items – concrete release agent.

Concrete release agent plays an important role in modern building building; its main role is always to form a layer of separation movie between the design and the concrete surface in order that the template will not adhere to the concrete area to ensure that it is easier to take down the form following pouring and to maintain the complete of the concrete surface. Here, we will introduce the sorts, features, utilization and program of concrete release agent in detail.

Sorts of concrete release agent

Concrete release representatives can be divided into several types according to different grouping strategies, and the frequent 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 emission agent for tunnels and so on.
• According to the composition: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
• According to the effect of use: it can be divided into ordinary concrete release brokers, 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 known as a concrete remoteness agent or mould release lubricant. It is a type of substance coated on the inner wall of the formwork to play the role of lubricating and separation in order that the concrete could be easily detached from the formwork when dismantling the formwork, and the condition 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 positive aspects of simple release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low cost and and so forth. However, not all sorts of concrete release agents with a selection of materials made of templates are suitable for different components of the template and different development circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the following characteristics:
Good isolation overall performance: concrete release agent can create a dense isolation film between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete covering and facilitating the removing.

Excellent lubrication efficiency: concrete release agent has good lubricating efficiency, which can decrease the rubbing between the formwork and concrete surface, decrease the resistance during pouring and improve the construction effectiveness.

Good anti-adhesion efficiency: concrete release representatives can efficiently avoid the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete covering when taking apart the formwork.

Excellent waterproof performance: concrete release agent has good waterproof overall performance, which can efficiently stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing the service life of the formwork.

Simple to use and safe: concrete release agent is effortless 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 surface, 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 development projects, mainly including the following aspects:

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

In conclusion, concrete release agent, as an essential 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the development of the construction industry.
