What is a concrete release agent?
A concrete release agent is a substance applied to the construction template just before the concrete is poured so that the design doesn’t adhere to the concrete covering right after flowing, isn’t effortless to take down the cast or affects the end of the concrete area. Its main role within the template and the concrete surface to develop a movie that will be separated from the two is additionally known as an separation agent.
A water-based release agent is surely an important supplementary in the release agent and can modify the water-based release agent stream and levelling; its main characteristic is definitely stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based mould release agent is used in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form products aren’t just to be able to let the mould release to improve productivity and prolong the life of the mould make use of. And can make the item thoroughly clean, size qualified, and lower the creation of scrap, which can be an essential additive important to forms and goods – concrete release agent.
Concrete release agent plays an important role within modern building construction; its primary role is to develop a layer of separation movie between the template and the concrete covering so that the design will not stick to to the concrete surface in order that it is simpler to dismantle the form following flowing and to maintain the end of the concrete surface. Here, we will unveil the types, characteristics, utilization and use of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release agents can be divided into numerous kinds based on different classification techniques, and the common classification strategies are as follows:
- According to the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete launch agent for tunnels and and so forth.
- According to the the composition of: it can be divided into water-based concrete release brokers, petroleum-based concrete release brokers, 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 representatives, high-gloss concrete release agents and and so forth.
Qualities of Concrete release agent
A concrete release agent is also referred to as a concrete isolation agent or mould release lubricant. It is a kind of compound coated on the inner wall of the formwork to play the function of lubrication and isolation so that the concrete may be effortlessly detached from the formwork when dismantling the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete area, no corrosion of the template, easy to paint, low price and etc. However, not all kinds of concrete release representatives with a selection of materials made of templates are suitable for different materials of the template and different construction circumstances 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 separation efficiency: concrete release agent can form a dense separation film between the formwork and the concrete covering, successfully avoiding the formwork from bonding with the concrete area and facilitating the dismantling.
Excellent lubrication performance: concrete release agent has good lubricating performance, which can reduce the chaffing between the formwork and concrete surface, lower the resistance during pouring and boost the construction productivity.
Excellent anti-adhesion overall performance: concrete release representatives can successfully avoid the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when taking apart the formwork.
Good waterproof overall performance: concrete release agent has good waterproof performance, which can successfully prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing the service life of the formwork.
Effortless 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 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 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 construction of a reinforced concrete structure, concrete release agents 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 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 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 construction projects.
In conclusion, concrete release agent, as an important 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 improve the construction efficiency and quality of the construction project and provide a strong guarantee for the development of the development industry.
