What is a concrete release agent?

A concrete release agent is actually a material placed on the construction template before the concrete is put so that the design will not stick to to the concrete surface following putting, isn’t simple to take apart the cast or influences the complete of the concrete surface. Its primary role within the template and the concrete area to develop a motion picture that will probably be separated from the two is additionally known as an remoteness agent.

A water-based release agent is definitely an important supplementary inside the release agent and can change the water-based release agent stream and levelling; its principal feature is actually stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based cast release agent is used in forms and products functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items aren’t just so as to let the cast release to enhance productivity and prolong the life of the form use. And can make the product thoroughly clean, size qualified, and decrease the creation of scrap, that is an crucial additional essential to forms and products – concrete release agent.

Concrete release agent plays an important role inside modern building construction; its primary role is to form a layer of remoteness movie between the design and the concrete covering in order that the template doesn’t stick to to the concrete area so that it is easier to take apart the mould after flowing and to maintain the complete of the concrete surface. Here, we will unveil the kinds, characteristics, utilization and application of concrete release agent at length.

Sorts of concrete release agent

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

Features of Concrete release agent

A concrete release agent can also be known as a concrete isolation agent or mould release lubricant. It is really a sort of substance coated on the inner wall of the formwork to play the role of lubricating and remoteness so that the concrete can be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release substance 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 etc. However, not all sorts of concrete release agents with a array of components made of templates are suitable for different materials of the template and different building circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the following qualities:
Good remoteness efficiency: concrete release agent can create a dense remoteness movie between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the dismantling.

Great lubrication overall performance: concrete release agent has good lubricating efficiency, which can reduce the friction between the formwork and concrete covering, decrease the resistance during pouring and boost the construction efficiency.

Excellent anti-adhesion performance: concrete release representatives can efficiently prevent the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete surface when dismantling the formwork.

Great waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively 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 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 covering gradually. In case of tight bonding between the formwork and the concrete area, 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 building 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 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 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 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 development projects. By choosing the right kind, 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 development industry.
