What is actually a concrete release agent?
A concrete release agent is actually a material placed on the development template before the concrete is put in order that the template does not adhere to the concrete surface after flowing, is just not simple to take down the mould or influences the finish of the concrete area. Its main role in the template and the concrete surface to create a film that is going to be separated from the two can also be called an separation agent.
A water-based release agent is definitely an essential ancillary inside the release agent and can change the water-based release agent stream and levelling; its principal attribute is stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based mould release agent is used in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items aren’t just so as to let the mould release to enhance productivity and extend the life of the cast make use of. And can make the product clear, size qualified, and decrease the creation of scrap, which can be an essential additional essential to casts and items – concrete release agent.
Concrete release agent plays an important role inside modern building development; its main role would be to create a layer of remoteness motion picture between the template and the concrete covering to ensure that the design does not stick to the concrete covering so that it is simpler to dismantle the cast right after pouring and to maintain the end of the concrete covering. Here, we will introduce the types, features, utilization and application of concrete release agent in detail.
Kinds of concrete release agent
Concrete release agents can be divided into several types based on different classification methods, and the frequent classification techniques 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 emission agent for tunnels and and so forth.
- According to the the composition of: it can be divided into water-based concrete release agents, oil-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release agents, high-gloss concrete release agents and so on.
Features of Concrete release agent
A concrete release agent is also called a concrete separation agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the part of lubrication and separation in order that the concrete may be effortlessly 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 materials motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete area, no corrosion of the template, simple to paint, low value and and so forth. However, not all sorts of concrete release brokers with a array 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 essential construction auxiliary material, concrete release agent has the subsequent features:
Good remoteness overall performance: concrete release agent can form a dense remoteness film between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete covering and facilitating the removing.
Great lubrication performance: concrete release agent has good lubrication overall performance, which can decrease the chaffing between the formwork and concrete covering, decrease the resistance during pouring and enhance the construction efficiency.
Good anti-adhesion efficiency: concrete release representatives can effectively prevent the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete area when taking down the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof performance, which can successfully avoid 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 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 surface.
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 area 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 area, 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 building of a reinforced concrete structure, concrete release representatives 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 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 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 enhance 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 type, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the construction industry.
