What is a concrete release agent?

A concrete release agent is definitely a material applied to the development design before the concrete is poured so that the template doesn’t stick to the concrete area after flowing, is not easy to take down the form or affects the finish of the concrete covering. Its main role in the template and the concrete covering to form a movie that is going to be separated from the two is also called an isolation agent.

A water-based release agent is definitely an important supplementary in the release agent and can alter the water-based release agent stream and levelling; its primary attribute is definitely stability to microorganisms and enzymes, which can decrease the expense 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 business, manufacturing mould goods aren’t just so as to let the cast release to boost productivity and prolong the life of the cast make use of. And can make the item clean, size qualified, and decrease the creation of scrap, which is an important additional important to forms and products – concrete additive.

Concrete release agent plays an essential role inside modern building development; its main role is to form a layer of remoteness motion picture between the template and the concrete covering so that the template doesn’t adhere to the concrete surface to ensure that it is much easier to dismantle the mould after pouring and to maintain the finish of the concrete surface. Here, we will unveil the types, qualities, usage and application of concrete release agent at length.

Sorts of concrete release agent

Concrete release agents can be divided into numerous kinds according to different category methods, and the frequent grouping techniques 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 composition of: it can be divided into water-based concrete release agents, petroleum-based concrete release brokers, silicone oil concrete release agents, etc.
• According to the effect of use: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release representatives, high-gloss concrete release representatives and and so forth.

Qualities of Concrete release agent

A concrete release agent can also be called a concrete isolation agent or mould release lubricant. It is a type of material coated on the inner wall of the formwork to play the function of lubrication and separation in order that the concrete can be easily detached from the formwork when taking apart 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, effortless to paint, low price and etc. However, not all kinds of concrete release agents with a selection of materials made of templates are suitable for different supplies of the template and different construction problems 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 form a dense isolation motion picture between the formwork and the concrete covering, effectively avoiding the formwork from bonding with the concrete area and facilitating the dismantling.

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

Good anti-adhesion performance: concrete release agents can successfully prevent the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete covering when taking apart the formwork.

Great waterproof overall performance: concrete release agent has good waterproof performance, which can effectively prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing 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 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 area 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 area, tools can be used appropriately to assist in the taking down.

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 building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, stopping 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 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 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 improve 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 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 boost the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the construction industry.
