What is actually a concrete release agent?

A concrete release agent is a material applied to the building template just before the concrete is poured so that the design will not stick to the concrete covering following flowing, is just not easy to take apart the mould or affects the finish of the concrete covering. Its primary role within the template and the concrete covering to form a movie that will probably be separated from the two can also be known as an remoteness agent.

A water-based release agent is definitely an crucial auxiliary within the release agent and can modify the water-based release agent stream and levelling; its main characteristic is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based cast release agent is used in casts and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould products are not only to be able to let the form release to enhance productivity and lengthen the life of the cast make use of. And can make the product clear, size qualified, and reduce the generation of scrap, which is an important additive vital to casts and goods – concrete additive.

Concrete release agent plays an crucial role inside modern building construction; its main role is to create a layer of isolation film between the template and the concrete area in order that the template does not stick to the concrete surface so that it is much easier to take down the form after flowing and to maintain the complete of the concrete covering. Here, we will unveil the kinds, features, use and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release agents can be divided into many sorts in accordance with different category techniques, and the frequent grouping strategies are the subsequent:

• According to the the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete discharge agent for tunnels and etc.
• According to the composition: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
• According to the the effect of use: it can be divided into ordinary concrete release agents, an easy task to remove concrete release agents, high-gloss concrete release representatives and so on.

Characteristics of Concrete release agent

A concrete release agent can also be referred to as a concrete isolation agent or mould release lubricant. It is actually a type of compound coated on the inner wall of the formwork to play the part of lubrication and remoteness so that the concrete may be effortlessly detached from the formwork when taking apart the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low cost and and so forth. However, not all sorts of concrete release brokers with a array of supplies 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 suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next qualities:
Good isolation performance: concrete release agent can develop a dense separation motion picture between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete surface and facilitating the demolding.

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

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

Excellent waterproof efficiency: concrete release agent has good waterproof efficiency, which can effectively stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing 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 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 apart 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 covering gradually. In case of tight bonding between the formwork and the concrete covering, tools can be used appropriately to assist in the taking down.

Clean up the template: after taking down 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 construction 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 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 area 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 boost 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 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 type, 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 development of the building industry.
