The Future of Water-Based Concrete Release Agents in Precast Concrete Products

What is a concrete release agent?

A concrete release agent is a material placed on the building design just before the concrete is poured so the design does not stick to to the concrete covering after flowing, is just not effortless to take apart the form or impacts the end of the concrete covering. Its main role in the template and the concrete covering to create a film that will be separated from the two can also be known as an separation agent.

A water-based release agent is definitely an important auxiliary in the release agent and can modify the water-based release agent flow and levelling; its main feature is definitely stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based mould release agent is used in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould products aren’t just in order to let the cast release to enhance productivity and prolong the life of the mould make use of. And can make the item thoroughly clean, size qualified, and decrease the technology of scrap, which is an essential additional essential to moulds and items – Water-based Concrete Release Agent.

Concrete release agent plays an important role in modern building construction; its primary role is to form a layer of isolation film between the design and the concrete covering to ensure that the template doesn’t stick to to the concrete surface so that it is easier to take down the cast after flowing and to maintain the finish of the concrete area. Here, we will introduce the types, characteristics, usage and program of concrete release agent at length.

Types of concrete release agent

Concrete release agents can be divided into several sorts according to different classification strategies, and the typical category techniques 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 etc.
  • According to the composition of: it can be divided into water-based concrete release representatives, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
  • According to the effect of use: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release brokers, high-gloss concrete release brokers and etc.

Features of Concrete release agent

A concrete release agent can also be called a concrete separation agent or mould release lubricant. It is actually a kind of material coated on the inner wall of the formwork to play the function of lubricating and remoteness so that the concrete could be easily detached from the formwork when taking down the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low value and etc. However, not all types of concrete release brokers with a variety of materials made of templates are suitable for different components of the template and different building circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the subsequent characteristics:
Good isolation overall performance: concrete release agent can form a dense separation motion picture between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete surface and facilitating the dismantling.

Good lubrication performance: concrete release agent has good lubrication efficiency, which can reduce the friction between the formwork and concrete covering, lower the resistance during pouring and enhance the construction efficiency.

Excellent anti-adhesion performance: concrete release representatives can effectively avoid the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete covering when taking down the formwork.

Excellent waterproof performance: concrete release agent has good waterproof efficiency, which can effectively 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.

Simple to use and safe: concrete release agent is simple 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 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 covering, 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 construction 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, 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 covering, 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 development projects.

In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern building 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 building project and provide a strong guarantee for the advancement of the development industry.
