What is actually a concrete release agent?

A concrete release agent is a substance applied to the construction template just before the concrete is poured in order that the design will not stick to the concrete area right after putting, is not effortless to take down the mould or influences the finish of the concrete surface. Its principal role in the template and the concrete covering to develop a movie that will be separated from the two can also be known as an remoteness agent.

A water-based release agent is definitely an essential supplementary inside the release agent and can modify the water-based release agent flow and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent is used in forms and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items are not just in order to let the cast release to improve productivity and prolong the life of the form use. And can make the item thoroughly clean, size qualified, and decrease the technology of scrap, that is an essential additional vital to forms and goods – Water-based Concrete Release Agent.

Concrete release agent plays an important role within modern building construction; its main role is always to form a layer of separation film between the design and the concrete covering to ensure that the design doesn’t stick to the concrete surface so that it is much easier to take apart the form right after flowing and to maintain the complete of the concrete area. Here, we will present the sorts, characteristics, usage and application of concrete release agent in detail.

Types of concrete release agent

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

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

Characteristics of Concrete release agent

A concrete release agent is additionally known as a concrete separation agent or mould release lubricant. It is a kind of substance coated on the inner wall of the formwork to play the part of lubricating and isolation in order that the concrete may be easily detached from the formwork when dismantling the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low value and and so forth. However, not all kinds of concrete release brokers with a array of materials made of templates are suitable for different materials 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 characteristics:
Good separation efficiency: concrete release agent can create a dense remoteness motion picture between the formwork and the concrete covering, efficiently stopping the formwork from bonding with the concrete area and facilitating the removing.

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

Good anti-adhesion efficiency: concrete release representatives can effectively avoid the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.

Good waterproof performance: concrete release agent has good waterproof performance, which can efficiently prevent moisture from penetrating between the formwork and concrete, preventing 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 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 area 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 apart 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 representatives 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 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 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 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 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 sort, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the building project and provide a strong guarantee for the advancement of the construction industry.
