What exactly is a concrete release agent?
A concrete release agent is a substance placed on the building template before the concrete is poured in order that the template will not stick to the concrete covering after pouring, is not simple to take down the cast or affects the end of the concrete covering. Its main role inside the template and the concrete area to develop a movie that will probably be separated from the two is also known as an remoteness agent.
A water-based release agent is surely an crucial ancillary inside the release agent and can modify the water-based release agent stream and levelling; its main attribute is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent is utilized in casts and items functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing form goods are not just to be able to let the mould release to boost productivity and lengthen the life of the cast make use of. And can make the product clear, size qualified, and reduce the creation of scrap, which is an essential supplementary essential to casts and goods – concrete additive.
Concrete release agent plays an important role inside modern building development; its primary role is always to create a layer of separation film between the design and the concrete covering in order that the template does 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 area. Here, we will introduce the sorts, qualities, use and application of concrete release agent in detail.
Types of concrete release agent
Concrete release representatives can be divided into many types based on different classification strategies, and the typical classification techniques are the following:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete discharge agent for tunnels and so on.
- According to the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release brokers, silicone oil concrete release agents, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release agents, high-gloss concrete release representatives and so on.
Features of Concrete release agent
A concrete release agent is also referred to as a concrete separation agent or mould release lubricant. It is a type of substance coated on the inner wall of the formwork to play the part of lubricating and isolation to ensure that the concrete may be smoothly detached from the formwork when taking down the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low value and and so forth. However, not all sorts of concrete release brokers with a variety of components made of templates are suitable for different components of the template and different construction circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the subsequent qualities:
Good separation efficiency: concrete release agent can form a dense isolation motion picture between the formwork and the concrete surface, efficiently preventing the formwork from bonding with the concrete area and facilitating the dismantling.
Great lubrication overall performance: concrete release agent has good lubricating performance, which can decrease the chaffing between the formwork and concrete surface, reduce the resistance during pouring and enhance the construction productivity.
Great anti-adhesion overall performance: concrete release brokers can successfully avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete covering when taking apart the formwork.
Great waterproof overall performance: concrete release agent has good waterproof efficiency, which can effectively stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing the service life of the formwork.
Effortless 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 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 surface gradually. In case of tight bonding between the formwork and the concrete covering, tools can be used appropriately to assist in the taking apart.
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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing 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 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 area and boost 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 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 essential construction auxiliary material, plays an indispensable role in modern development 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 building project and provide a strong guarantee for the advancement of the development industry.
