Exploring the Chemistry Behind Concrete Additives

What is a concrete release agent?

A concrete release agent is a material put on the development design prior to the concrete is poured in order that the template will not stick to to the concrete surface right after flowing, is just not easy to dismantle the cast or influences the finish of the concrete surface. Its principal role in the template and the concrete covering to form a motion picture that is going to be separated from the two is also known as an separation agent.

A water-based release agent is an important ancillary in the release agent and can alter the water-based release agent stream and levelling; its primary characteristic is stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based form release agent is used in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form products are not only in order to let the mould release to boost productivity and prolong the life of the mould use. And can make the product clean, size qualified, and reduce the technology of scrap, which is an essential additional important to casts and products – concrete additive.

Concrete release agent plays an essential role inside modern building construction; its primary role would be to form a layer of remoteness film between the design and the concrete area so that the template does not adhere to the concrete area in order that it is easier to dismantle the mould right after flowing and to maintain the end of the concrete surface. Here, we will present the sorts, characteristics, use and use of concrete release agent at length.

Kinds of concrete release agent

Concrete release agents can be divided into several sorts in accordance with different category techniques, and the common category methods are the subsequent:

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

Qualities of Concrete release agent

A concrete release agent is also referred to 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 remoteness so that the concrete may be easily detached from the formwork when taking down the formwork, and the condition 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 advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low price and etc. However, not all types of concrete release agents with a variety of components made of templates are suitable for different supplies of the template and different construction conditions and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next characteristics:
Good remoteness performance: concrete release agent can create a dense isolation movie between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete area and facilitating the removing.

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

Excellent anti-adhesion efficiency: concrete release representatives can efficiently avoid the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete surface when taking apart the formwork.

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

Effortless 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 dismantling 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 area gradually. In case of tight bonding between the formwork and the concrete area, 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 development projects, mainly including the following aspects:

Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release agents can be used for formwork isolation, avoiding 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 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 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 crucial construction auxiliary material, plays an indispensable role in modern construction 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 development project and provide a strong guarantee for the development of the development industry.
