What exactly is a concrete release agent?
A concrete release agent is definitely a substance put on the construction design before the concrete is put so the template will not stick to to the concrete covering following flowing, is just not effortless to dismantle the cast or affects the finish of the concrete covering. Its principal role in the design and the concrete surface to create a film that will probably be separated from the two is also known as an isolation 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 main 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 moulds and goods functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing mould products are not only in order to let the cast release to boost productivity and extend the life of the mould utilize. And can make the item thoroughly clean, size qualified, and decrease the generation of scrap, that is an crucial additional vital to casts and products – Water-based Concrete Release Agent.
Concrete release agent plays an important role inside modern building development; its main role is always to form a layer of remoteness motion picture between the design and the concrete area to ensure that the template will not adhere to the concrete surface in order that it is simpler to take down the form following pouring and to maintain the end of the concrete covering. Here, we will present the kinds, features, usage and application of concrete release agent in detail.
Sorts of concrete release agent
Concrete release agents can be divided into several sorts based on different category techniques, and the common classification strategies 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 launch agent for tunnels and so on.
- According to the composition of: it can be divided into water-based concrete release agents, oil-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the effect of use: it can be divided into ordinary concrete release agents, an easy task to remove concrete release representatives, high-gloss concrete release brokers and and so forth.
Qualities of Concrete release agent
A concrete release agent is additionally referred to as a concrete remoteness agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the role of lubricating and remoteness in order that the concrete may be easily detached from the formwork when taking down the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete covering, no corrosion of the template, simple 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 materials 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 important construction auxiliary material, concrete release agent has the following characteristics:
Good remoteness overall performance: concrete release agent can form a dense separation movie between the formwork and the concrete area, efficiently preventing the formwork from bonding with the concrete surface and facilitating the demolding.
Good lubrication overall performance: concrete release agent has good lubricating efficiency, which can lower the chaffing between the formwork and concrete surface, decrease the resistance during pouring and improve the construction efficiency.
Excellent anti-adhesion performance: concrete release representatives can successfully avoid the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete area when taking apart the formwork.
Excellent waterproof efficiency: 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.
Easy 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 covering.
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 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 construction 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 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 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 improve 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 construction projects.
In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right kind, 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 growth of the building industry.
