What is a concrete release agent?

A concrete release agent is definitely a material placed on the building template just before the concrete is put so the template will not adhere to the concrete area following pouring, is not effortless to take down the mould or affects the end of the concrete area. Its main role within the template and the concrete covering to form a movie that is going to be separated from the two can also be called an remoteness agent.

A water-based release agent is surely an essential auxiliary within the release agent and can alter the water-based release agent circulation and levelling; its primary characteristic is actually stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based form release agent can be used in casts and products functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing mould items aren’t just so as to let the mould release to enhance productivity and prolong the life of the cast make use of. And can make the product clear, size qualified, and decrease the creation of scrap, that is an essential additive vital to forms and products – concrete release agent.

Concrete release agent plays an important role in modern building construction; its principal role is to form a layer of isolation motion picture between the template and the concrete covering to ensure that the template doesn’t stick to to the concrete area in order that it is easier to dismantle the cast after pouring and to maintain the complete of the concrete area. Here, we will present the types, features, utilization and program of concrete release agent in more detail.

Types of concrete release agent

Concrete release agents can be divided into numerous types in accordance with different grouping techniques, and the typical category methods are the following:

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

Characteristics of Concrete release agent

A concrete release agent is additionally referred to as a concrete separation agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the function of lubricating and remoteness to ensure that the concrete can be smoothly detached from the formwork when dismantling the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low cost and so on. However, not all types of concrete release representatives with a selection of components 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 suitable 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 form a dense remoteness movie between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the removing.

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

Excellent anti-adhesion overall performance: concrete release brokers can efficiently stop the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete area when taking down the formwork.

Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can efficiently stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving 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 covering.

Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking down 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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release agents can be used for formwork isolation, avoiding 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 surface and enhance 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 representatives 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 development 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 development industry.
