Examining the Effects of Concrete Additives on Rheology and Fresh Properties

What is a concrete release agent?

A concrete release agent is definitely a material applied to the development template before the concrete is poured in order that the template does not stick to to the concrete covering after putting, isn’t simple to take down the form or impacts the finish of the concrete area. Its primary role inside the template and the concrete area to form a movie that will be separated from the two is additionally called an remoteness agent.

A water-based release agent is an essential supplementary inside the release agent and can modify the water-based release agent flow and levelling; its principal characteristic is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent is utilized in forms and items functional processing additives; in the rubber, plastic, and Jinsu processing business, manufacturing form products are not only so as to let the mould release to enhance productivity and prolong the life of the cast utilize. And can make the product clear, size qualified, and reduce the technology of scrap, which can be an essential supplementary important to moulds and items – concrete additive.

Concrete release agent plays an important role inside modern building building; its principal role is always to form a layer of separation movie between the template and the concrete surface to ensure that the template does not stick to to the concrete covering so that it is simpler to take apart the cast following pouring and to maintain the complete of the concrete surface. Here, we will present the kinds, qualities, utilization and program of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release representatives can be divided into numerous types based on different category methods, and the typical classification methods are the subsequent:

  • According to the the opportunity of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete emission agent for tunnels and and so forth.
  • According to the the formula of: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release representatives, etc.
  • According to the the effect of use: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release agents, high-gloss concrete release representatives and so on.

Features of Concrete release agent

A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is actually a sort of compound coated on the inner wall of the formwork to play the function of lubricating and isolation so that the concrete could be easily detached from the formwork when dismantling the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low price and so on. However, not all kinds of concrete release agents with a selection of supplies made of templates are suitable for different supplies of the template and different construction conditions and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the next features:
Good separation performance: concrete release agent can form a dense isolation motion picture between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete area and facilitating the dismantling.

Good lubrication overall performance: concrete release agent has good lubricating overall performance, which can reduce the rubbing between the formwork and concrete surface, reduce the resistance during pouring and boost the construction productivity.

Excellent anti-adhesion overall performance: concrete release representatives can effectively stop the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when dismantling the formwork.

Great waterproof performance: concrete release agent has good waterproof performance, which can efficiently prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.

Effortless 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 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 surface.

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 surface 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 taking apart 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 development 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 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 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 building projects.

In conclusion, concrete release agent, as an essential 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 improve the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the building industry.
