What exactly is a concrete release agent?
A concrete release agent is actually a substance placed on the building template prior to the concrete is poured so the template doesn’t stick to to the concrete surface following pouring, isn’t easy to take down the cast or influences the end of the concrete area. Its primary role in the template and the concrete area to form a motion picture that is going to be separated from the two can also be known as an separation agent.
A water-based release agent is an crucial ancillary inside the release agent and can change the water-based release agent flow and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent can be used in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing mould goods are not only so as to let the cast release to enhance productivity and lengthen the life of the cast utilize. And can make the item clean, size qualified, and reduce the technology of scrap, which is an important additional essential to forms and products – concrete additive.
Concrete release agent plays an important role within modern building building; its primary role is to form a layer of isolation film between the design and the concrete area in order that the template doesn’t stick to to the concrete area in order that it is simpler to take down the cast following putting and to maintain the complete of the concrete covering. Here, we will introduce the kinds, features, use and program of concrete release agent at length.
Types of concrete release agent
Concrete release agents can be divided into several types according to different grouping techniques, and the common category strategies 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 release agent for tunnels and etc.
- According to the composition of: it can be divided into water-based concrete release representatives, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release representatives, high-gloss concrete release brokers and so on.
Characteristics of Concrete release agent
A concrete release agent is also called a concrete separation agent or mould release lubricant. It is really a sort of substance coated on the inner wall of the formwork to play the part of lubricating and separation so that the concrete could be smoothly detached from the formwork when taking apart the formwork, and the condition 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 benefits of simple release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low value and etc. However, not all kinds of concrete release agents with a selection of supplies 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 ideal release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the following features:
Good remoteness overall performance: concrete release agent can develop a dense isolation motion picture between the formwork and the concrete surface, effectively preventing the formwork from bonding with the concrete area and facilitating the dismantling.
Good lubrication overall performance: concrete release agent has good lubrication overall performance, which can reduce the chaffing between the formwork and concrete surface, decrease the resistance during pouring and enhance the construction effectiveness.
Excellent anti-adhesion overall performance: concrete release agents can successfully prevent the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete surface when taking apart the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can efficiently prevent 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 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 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 area of the formwork should be knocked gently to separate the formwork from the concrete area gradually. In case of tight bonding between the formwork and the concrete surface, 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 building 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, stopping 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 surface, 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 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 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 development projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern construction 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 construction project and provide a strong guarantee for the growth of the building industry.
