What is actually a concrete release agent?

A concrete release agent is definitely a compound put on the development template prior to the concrete is put in order that the design will not stick to the concrete area after putting, isn’t effortless to take apart the cast or affects the complete of the concrete area. Its primary role within the template and the concrete covering to create a film that is going to be separated from the two is also referred to as an separation agent.

A water-based release agent is an essential supplementary within the release agent and can alter the water-based release agent flow and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based mould release agent is used in moulds and products functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing mould goods aren’t just to be able to let the mould release to boost productivity and lengthen the life of the cast utilize. And can make the product clean, size qualified, and reduce the generation of scrap, which is an crucial additive vital to moulds and goods – concrete additive.

Concrete release agent plays an essential role inside modern building development; its principal role is to create a layer of isolation film between the design and the concrete surface so that the design does not stick to to the concrete covering so that it is simpler to take apart the cast after flowing and to maintain the end of the concrete area. Here, we will introduce the kinds, characteristics, utilization and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release brokers can be divided into many sorts based on different grouping techniques, and the common category strategies are the subsequent:

• According to the opportunity 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 of: it can be divided into water-based concrete release agents, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
• According to the the utilization effect: it can be divided into ordinary concrete release agents, 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 also known as 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 role of lubricating and isolation to ensure that the concrete could be smoothly detached from the formwork when taking apart the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete area, no corrosion of the template, simple to paint, low cost and and so forth. However, not all types of concrete release brokers with a variety of materials made of templates are suitable for different components of the template and different construction problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the following features:
Good separation performance: concrete release agent can create a dense remoteness motion picture between the formwork and the concrete covering, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the demolding.

Great lubrication performance: concrete release agent has good lubricating overall performance, which can reduce the rubbing between the formwork and concrete area, lower the resistance during pouring and boost the construction productivity.

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

Good waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.

Effortless 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 surface.

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 area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking down.

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 development of a reinforced concrete structure, concrete release agents can be used for formwork isolation, preventing 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 area and boost 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 development projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern building 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 construction project and provide a strong guarantee for the advancement of the building industry.
