What is a concrete release agent?

A concrete release agent is a substance put on the development template prior to the concrete is put so that the design will not stick to the concrete covering following flowing, is not easy to dismantle the cast or influences the end of the concrete area. Its primary role in the design and the concrete covering to create a film that is going to be separated from the two is additionally known as an separation agent.

A water-based release agent is surely an crucial auxiliary in the release agent and can change the water-based release agent circulation and levelling; its principal characteristic is definitely stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based mould release agent is used in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing business, manufacturing cast items are not just so as to let the cast release to boost productivity and extend the life of the form make use of. And can make the merchandise clean, size qualified, and decrease the technology of scrap, which is an essential additive vital to forms and products – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role inside modern building building; its principal role is to develop a layer of remoteness film between the design and the concrete surface in order that the template doesn’t adhere to the concrete surface so that it is easier to take apart the mould right after putting and to maintain the finish of the concrete area. Here, we will present the kinds, qualities, use and use of concrete release agent at length.

Kinds of concrete release agent

Concrete release agents can be divided into several types based on different classification strategies, and the typical classification methods are the subsequent:

• According to the 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 the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release brokers, silicone oil concrete release representatives, etc.
• According to the effect of use: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release agents, high-gloss concrete release brokers and etc.

Features of Concrete release agent

A concrete release agent is also known as a concrete separation agent or mould release lubricant. It is really a kind of compound coated on the inner wall of the formwork to play the function of lubricating and separation to ensure that the concrete may be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete can 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 simple release, no pollution of the concrete area, no corrosion of the template, simple to paint, low value and and so forth. However, not all sorts of concrete release agents with a array of supplies 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 crucial construction auxiliary material, concrete release agent has the next qualities:
Good separation performance: concrete release agent can create a dense remoteness movie between the formwork and the concrete covering, efficiently preventing the formwork from bonding with the concrete covering and facilitating the dismantling.

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

Good anti-adhesion overall performance: concrete release agents can successfully stop the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete surface when dismantling the formwork.

Excellent waterproof efficiency: concrete release agent has good waterproof performance, which can effectively prevent moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing the service life of the formwork.

Easy 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 surface.

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 surface 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 taking apart.

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 construction 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, stopping formwork from bonding with concrete and increasing 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 area, 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 agents 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 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 boost the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the building industry.
