What is a concrete release agent?

A concrete release agent is actually a substance placed on the development design just before the concrete is put in order that the design doesn’t stick to the concrete area following putting, is just not effortless to dismantle the form or impacts the finish of the concrete area. Its primary role in the design and the concrete covering to develop a movie that will be separated from the two is additionally known as an isolation agent.

A water-based release agent is surely an important supplementary inside the release agent and can modify the water-based release agent stream and levelling; its primary attribute is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based mould release agent can be used in moulds and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items are not only in order to let the mould release to improve productivity and prolong the life of the mould utilize. And can make the product thoroughly clean, size qualified, and reduce the generation of scrap, which is an essential supplementary essential to forms and goods – Water-based Concrete Release Agent.

Concrete release agent plays an essential role within modern building development; its principal role would be to develop a layer of remoteness movie between the template and the concrete area so that the template doesn’t stick to the concrete surface so that it is easier to dismantle the mould after pouring and to maintain the end of the concrete area. Here, we will introduce the sorts, qualities, utilization and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release agents can be divided into many kinds based on different grouping strategies, and the frequent grouping strategies are the following:

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

Qualities of Concrete release agent

A concrete release agent is also referred to as a concrete isolation agent or mould release lubricant. It is really a kind of material coated on the inner wall of the formwork to play the role of lubrication and remoteness to ensure that the concrete could be smoothly detached from the formwork when taking apart the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low cost and etc. However, not all sorts of concrete release agents with a selection of materials made of templates are suitable for different components of the template and different development circumstances 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 features:
Good separation efficiency: concrete release agent can form a dense isolation motion picture between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the dismantling.

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

Excellent anti-adhesion overall performance: concrete release representatives 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 prevent moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and increasing the service life of the formwork.

Simple 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 taking apart 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 area 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 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 development of a reinforced concrete structure, concrete release agents can be used for formwork isolation, preventing 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 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 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 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 development projects.

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