What is actually a concrete release agent?
A concrete release agent is actually a material placed on the building design just before the concrete is added so that the template doesn’t stick to the concrete covering following putting, isn’t simple to take down the mould or affects the complete of the concrete area. Its principal role in the template and the concrete surface to create a movie that will be separated from the two is additionally known as an isolation agent.
A water-based release agent is an crucial supplementary within the release agent and can alter the water-based release agent flow and levelling; its primary attribute is definitely stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based cast release agent is used in moulds and items functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form goods are not just so as to let the mould release to enhance productivity and prolong the life of the mould utilize. And can make the merchandise thoroughly clean, size qualified, and reduce the technology of scrap, which can be an important additional essential to moulds and goods – concrete release agent.
Concrete release agent plays an crucial role within modern building construction; its primary role is always to form a layer of separation movie between the template and the concrete area in order that the template will not stick to the concrete area to ensure that it is simpler to take down the cast following pouring and to maintain the end of the concrete covering. Here, we will unveil the sorts, characteristics, usage and use of concrete release agent in detail.
Sorts of concrete release agent
Concrete release agents can be divided into numerous kinds according to different classification strategies, and the typical grouping techniques 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 release agent for tunnels and so on.
- According to the composition: it can be divided into water-based concrete release brokers, oil-based concrete release representatives, silicone oil concrete release agents, etc.
- According to the effect of use: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release brokers, high-gloss concrete release agents and etc.
Qualities of Concrete release agent
A concrete release agent is also known as a concrete separation agent or mould release lubricant. It is really a kind of substance coated on the inner wall of the formwork to play the function of lubricating and remoteness to ensure that the concrete can be effortlessly detached from the formwork when taking apart the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete area, no corrosion of the template, easy to paint, low cost and etc. However, not all sorts of concrete release agents with a array of supplies 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 ideal release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the subsequent characteristics:
Good isolation overall performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete covering and facilitating the demolding.
Excellent lubrication performance: concrete release agent has good lubricating efficiency, which can reduce the rubbing between the formwork and concrete area, lower the resistance during pouring and enhance the construction effectiveness.
Great anti-adhesion performance: concrete release representatives can effectively prevent the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete surface when taking apart the formwork.
Good waterproof efficiency: concrete release agent has good waterproof performance, which can efficiently 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 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 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 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 development of a reinforced concrete structure, concrete release agents 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 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 surface 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 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 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 construction project and provide a strong guarantee for the growth of the development industry.
