Effective Strategies for Incorporating Concrete Additives in Precast Elements

What is a concrete release agent?

A concrete release agent is a material placed on the development design just before the concrete is added in order that the template doesn’t stick to to the concrete surface after pouring, is not effortless to dismantle the mould or impacts the complete of the concrete surface. Its main role within the template and the concrete covering to create a motion picture that is going to be separated from the two can also be referred to as an remoteness agent.

A water-based release agent is definitely an essential supplementary within the release agent and can alter the water-based release agent flow and levelling; its principal feature is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is utilized in forms and items functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form items are not just to be able to let the mould release to boost productivity and prolong the life of the mould utilize. And can make the item clean, size qualified, and decrease the generation of scrap, that is an important supplementary important to forms and items – Water-based Concrete Release Agent.

Concrete release agent plays an essential role inside modern building construction; its primary role is always to form a layer of remoteness motion picture between the template and the concrete surface so that the template does not stick to to the concrete surface to ensure that it is much easier to dismantle the cast right after putting and to maintain the end of the concrete area. Here, we will unveil the kinds, qualities, usage and application of concrete release agent in detail.

Types of concrete release agent

Concrete release agents can be divided into several types in accordance with different grouping techniques, and the frequent grouping strategies are the following:

  • According to the the scope 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 formula of: it can be divided into water-based concrete release brokers, petroleum-based concrete release brokers, silicone oil concrete release representatives, etc.
  • According to the the effect of use: it can be divided into ordinary concrete release agents, easy-to-remove concrete release brokers, high-gloss concrete release brokers and so on.

Characteristics of Concrete release agent

A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is really a kind of material coated on the inner wall of the formwork to play the part of lubricating and isolation to ensure that the concrete may be easily detached from the formwork when taking apart the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low price and etc. However, not all sorts of concrete release agents with a array of materials made of templates are suitable for different components of the template and different building conditions and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the subsequent qualities:
Good remoteness performance: concrete release agent can form a dense isolation film between the formwork and the concrete surface, efficiently preventing the formwork from bonding with the concrete area and facilitating the demolding.

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

Excellent anti-adhesion efficiency: concrete release agents 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 successfully avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing 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 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 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 surface, tools can be used appropriately to assist in the taking apart.

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, 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 covering and improve 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 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 building 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the building industry.
