The Impact of Concrete Additives on Strength and Durability

What is actually a concrete release agent?

A concrete release agent is a material applied to the development template before the concrete is poured so that the template does not adhere to the concrete surface right after pouring, is just not effortless to dismantle the form or impacts the complete of the concrete area. Its primary role in the design and the concrete area to form a movie that will probably be separated from the two is additionally called an isolation agent.

A water-based release agent is surely an crucial ancillary within the release agent and can modify the water-based release agent circulation and levelling; its primary characteristic is stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based mould release agent is used in forms and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form items aren’t just so as to let the mould release to boost productivity and extend the life of the mould use. And can make the product clear, size qualified, and decrease the generation of scrap, that is an essential supplementary vital to moulds and items – concrete release agent.

Concrete release agent plays an crucial role within modern building development; its primary role would be to create a layer of separation film between the template and the concrete covering in order that the template does not stick to to the concrete covering so that it is much easier to dismantle the mould following putting and to maintain the complete of the concrete surface. Here, we will introduce the kinds, qualities, utilization and use of concrete release agent in detail.

Types of concrete release agent

Concrete release agents can be divided into many types in accordance with different grouping strategies, and the common category strategies are the following:

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

Features of Concrete release agent

A concrete release agent is also referred to as a concrete remoteness 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 lubrication and remoteness so that the concrete could be effortlessly detached from the formwork when taking down the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the traditional release materials 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 value and and so forth. However, not all sorts of concrete release representatives 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 appropriate release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next features:
Good remoteness efficiency: concrete release agent can create a dense separation motion picture between the formwork and the concrete surface, effectively avoiding the formwork from bonding with the concrete surface and facilitating the demolding.

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

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

Great waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving 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 area.

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 covering 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 dismantling.

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 brokers 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 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 building projects.

In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right kind, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the construction project and provide a strong guarantee for the development of the development industry.
