The Role of Water-Based Concrete Release Agents in Achieving Quality Finishes

What is a concrete release agent?

A concrete release agent is actually a compound put on the construction design just before the concrete is added so the design will not adhere to the concrete surface after flowing, is just not simple to dismantle the form or affects the finish of the concrete covering. Its principal role in the template and the concrete area to create a movie that is going to be separated from the two can also be referred to as an remoteness agent.

A water-based release agent is 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 reduce the cost of raw materials. A water-based form release agent can be used in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing cast goods are not just in order to let the form release to boost productivity and lengthen the life of the cast use. And can make the product clear, size qualified, and lower the technology of scrap, which is an essential supplementary important to forms and items – concrete release agent.

Concrete release agent plays an essential role inside modern building construction; its main role would be to form a layer of remoteness film between the template and the concrete surface in order that the design doesn’t adhere to the concrete area in order that it is much easier to dismantle the form following pouring and to maintain the finish of the concrete surface. Here, we will unveil the types, characteristics, use and program of concrete release agent at length.

Sorts of concrete release agent

Concrete release agents can be divided into several sorts based on different classification techniques, and the common category techniques are the following:

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

Qualities of Concrete release agent

A concrete release agent is additionally known as a concrete separation agent or mould release lubricant. It is really a sort of substance coated on the inner wall of the formwork to play the part of lubricating and separation so that the concrete can be easily detached from the formwork when taking apart the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete area, no corrosion of the template, easy to paint, low value and and so forth. However, not all kinds of concrete release brokers with a selection of materials made of templates are suitable for different supplies of the template and different building circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next characteristics:
Good isolation performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete covering, effectively avoiding the formwork from bonding with the concrete area and facilitating the removing.

Excellent lubrication efficiency: concrete release agent has good lubrication overall performance, which can reduce the chaffing between the formwork and concrete surface, lower the resistance during pouring and improve the construction effectiveness.

Great anti-adhesion performance: concrete release brokers can efficiently prevent the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete covering when taking apart the formwork.

Good waterproof performance: concrete release agent has good waterproof performance, which can effectively avoid moisture from penetrating between the formwork and concrete, steering clear of 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 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 covering.

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 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 surface, 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 development projects, mainly including the following aspects:

Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, stopping 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 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 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 building projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern building 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 growth of the construction industry.
