The Benefits of Concrete Additives for Construction Projects

What exactly is a concrete release agent?

A concrete release agent is actually a material applied to the building design just before the concrete is added so that the design doesn’t adhere to the concrete area following putting, is just not simple to take down the mould or impacts the finish of the concrete area. Its main role within the template and the concrete covering to form a film that is going to be separated from the two is additionally known as an separation agent.

A water-based release agent is an important ancillary within the release agent and can change the water-based release agent flow and levelling; its principal attribute is stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based cast release agent is utilized in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing cast goods aren’t just so as to let the cast release to enhance productivity and prolong the life of the form make use of. And can make the product thoroughly clean, size qualified, and lower the generation of scrap, which can be an important supplementary essential to moulds and products – Water-based Concrete Release Agent.

Concrete release agent plays an important role within modern building construction; its main role is always to form a layer of isolation movie between the template and the concrete area to ensure that the template doesn’t stick to the concrete area in order that it is simpler to take apart the cast right after pouring and to maintain the finish of the concrete covering. Here, we will present the sorts, features, usage and application of concrete release agent at length.

Kinds of concrete release agent

Concrete release agents can be divided into several types in accordance with different classification methods, and the typical grouping methods are the subsequent:

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

Qualities of Concrete release agent

A concrete release agent can also be known as a concrete isolation agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the role of lubricating and separation so that the concrete could be easily detached from the formwork when taking down the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the traditional release material 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, effortless to paint, low price and so on. However, not all types of concrete release representatives with a array of components made of templates are suitable for different supplies of the template and different development circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the subsequent features:
Good isolation performance: concrete release agent can develop a dense remoteness movie between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the removing.

Good lubrication performance: concrete release agent has good lubricating performance, which can lower the rubbing between the formwork and concrete covering, decrease the resistance during pouring and improve the construction productivity.

Great anti-adhesion performance: concrete release representatives can effectively stop the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete surface when taking apart the formwork.

Excellent waterproof performance: concrete release agent has good waterproof performance, which can effectively avoid 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 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 covering gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the dismantling.

Clean up the template: after taking apart 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 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 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 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 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 construction projects.

In conclusion, concrete release agent, as an crucial 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 improve the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the development industry.
