What is actually a concrete release agent?

A concrete release agent is a material placed on the development template prior to the concrete is poured so that the template doesn’t stick to to the concrete covering following flowing, is just not simple to take apart the form or impacts the complete of the concrete surface. Its main role inside the template and the concrete surface to develop a movie that will probably be separated from the two can also be called an separation agent.

A water-based release agent is definitely an essential auxiliary inside the release agent and can modify the water-based release agent flow and levelling; its principal attribute is definitely stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based form release agent can be used in moulds and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items aren’t just so as to let the mould release to boost productivity and prolong the life of the mould use. And can make the item thoroughly clean, size qualified, and decrease the technology of scrap, that is an important additive vital to moulds and items – concrete additive.

Concrete release agent plays an crucial role within modern building development; its principal role would be to create a layer of isolation film between the template and the concrete covering so that the design will not adhere to the concrete surface in order that it is easier to take down the cast following putting and to maintain the end of the concrete surface. Here, we will unveil the types, qualities, usage and use of concrete release agent at length.

Sorts of concrete release agent

Concrete release agents can be divided into many sorts based on different grouping strategies, and the common category strategies are the subsequent:

• According to the opportunity 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 agents, oil-based concrete release representatives, silicone oil concrete release representatives, etc.
• According to the the utilization effect: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release agents, high-gloss concrete release representatives and etc.

Qualities of Concrete release agent

A concrete release agent is also referred to as a concrete separation agent or mould release lubricant. It is actually a kind of compound coated on the inner wall of the formwork to play the function of lubricating and isolation so that the concrete could be easily detached from the formwork when taking down the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the conventional release substance 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 price and and so forth. However, not all sorts of concrete release representatives with a selection of components made of templates are suitable for different components of the template and different construction conditions and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next qualities:
Good remoteness efficiency: concrete release agent can form a dense isolation motion picture between the formwork and the concrete surface, effectively stopping the formwork from bonding with the concrete covering and facilitating the removing.

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

Great anti-adhesion efficiency: concrete release agents can successfully avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete surface when taking apart the formwork.

Excellent waterproof efficiency: concrete release agent has good waterproof efficiency, which can efficiently stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing the service life of the formwork.

Simple to use and safe: concrete release agent is easy 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 surface.

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 surface 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 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, avoiding 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 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 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 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 construction 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 boost the construction efficiency and quality of the construction project and provide a strong guarantee for the advancement of the development industry.
