Climatic Chamber with CO2 Control for Building Material Carbonation Test

A climatic chamber with CO2 control is designed to provide precise environmental control of temperature, humidity, and CO2 levels. The CO2 control allows researchers to simulate the effects of atmospheric changes, such as global warming, on plant and animal life. This type of chamber is particularly useful for analyzing how different organisms respond to changing environmental conditions over time. This week, We have developed a new climatic chamber for testing hardened concrete with strength tests. It has to be said that this climatic chamber with CO2 control is a powerful design.

At present, for the concentration test of carbon dioxide on the market, The concentration test range of carbon dioxide that other manufacturers can promise is 0%~20%, But we can do 0% ~ 96%. Why do other manufacturers only promise that the concentration test range of carbon dioxide is 0%~20% ? The main reason is that the sensor for carbon dioxide concentration test purchased by other suppliers will not work successfully after a high temperature of 55°C, and we are well aware of this! Using the principle of the fluidity of air, We choose ventilation ducts to draw out the high-temperature air from the test room and cool it down.

Frequent sampling of the air from the test room and the concentration test of carbon dioxide can solve the problem that the carbon dioxide sensor cannot work under high-temperature conditions. Meanwhile, with frequent sampling’s help, the test data for the concentration of carbon dioxide is also very accurate. The climatic chamber with CO2 control for high-concentration testing is independently completed by the research and development team of Wewon Environmental Chambers Co., Ltd. It is currently in a leading position in the market and has no competitors there !

A climatic chamber with CO2 control is a valuable tool for researchers who want to study the effects of environmental conditions on living organisms. With precise control over temperature, humidity, and CO2 levels, these chambers enable scientists to create realistic simulations of real-world conditions, facilitating research and development in many fields.

Why is Carbonation Testing Relevant for Building Materials? Carbonation testing of building materials is often done in a climate chamber which allows for precise control of carbon dioxide (CO2) levels. Through the use of CO2 control, the environment inside the chamber can be precisely monitored and adjusted to recreate real-world conditions and determine how a given material may react under different circumstances.

What is the Difference Between BS EN 12390-2 Part 2: Making and Curing Specimens for Strength Tests and BS EN 12390-12 standard Part 12: Determination of the Carbonation Resistance of Concret – Accelerated Carbonation Method ?
A: The BS EN 12390-2 Part 2 and BS EN 12390-12 standards are both related to concrete testing, but they address different aspects of concrete performance.

BS EN 12390-2 Part 2: Making and Curing Specimens for Strength Tests specifies the procedures for making and curing concrete test specimens that are used to determine the compressive strength of the concrete. It provides guidelines for preparing the test specimens, which includes selecting the sampling location, sampling the concrete, and making and curing the specimens under controlled conditions.

On the other hand, BS EN 12390-12 Part 12: Determination of the Carbonation Resistance of Concrete – Accelerated Carbonation Method focuses on assessing the carbonation resistance of the concrete. Carbonation is a chemical process in which carbon dioxide from the atmosphere reacts with the calcium hydroxide in concrete to form calcium carbonate. This can potentially reduce the durability and service life of concrete structures. The standard provides a method for accelerated carbonation testing, which helps to evaluate the potential carbonation resistance of concrete under accelerated conditions.

In summary, BS EN 12390-2 Part 2 deals with the preparation and curing of concrete test specimens for determining compressive strength, while BS EN 12390-12 Part 12 focuses on evaluating the carbonation resistance of concrete through an accelerated carbonation testing method.

What’s the relationship of BS EN 12390-2 and BS EN 12390-12 test standard ?
A: BS EN 12390-2 and BS EN 12390-12 are both part of the BS EN 12390 series of European standards that cover various aspects of testing concrete. While they are related in the sense that they both pertain to concrete testing, they address different aspects of concrete performance.

BS EN 12390-2 Part 2: Making and Curing Specimens for Strength Tests provides guidelines for making and curing concrete test specimens that are used to determine the compressive strength of the concrete. It focuses on the procedures for preparing the specimens under controlled conditions, which is essential for obtaining accurate and reliable strength test results.

On the other hand, BS EN 12390-12 Part 12: Determination of the Carbonation Resistance of Concrete – Accelerated Carbonation Method focuses on assessing the carbonation resistance of concrete. Carbonation is a chemical process that can affect the durability of concrete structures. This standard provides a method for accelerated carbonation testing, which helps evaluate the potential carbonation resistance of concrete under accelerated conditions.

BS EN 12390-2 Part 2 deals with specimen preparation for strength testing, while BS EN 12390-12 Part 12 focuses on evaluating the carbonation resistance of concrete. Both standards contribute to the overall understanding of concrete performance and help ensure the quality and durability of concrete structures.

Does the BS EN 12390-2 standard need a Climatic Chamber with CO2 Control to CO2 concentration for testing concrete samples ? If so, Please Describe in Detail.
A: No, The BS EN 12390-2 standard “Testing fresh concrete – Part 2: Slump test” does not have specific CO2 concentration requirements for testing concrete samples.

BS EN 12390-2 primarily focuses on the slump test, which is a measure of the consistency and workability of fresh concrete. The standard specifies the apparatus, sampling procedures, and testing method for determining the slump of concrete.

The slump test involves filling a standard slump cone with concrete, compacting it, and then removing the cone to measure the settlement of the concrete. This test helps assess the workability and flow characteristics of the concrete.

While the BS EN 12390-2 standard does not include CO2 concentration requirements, it is worth noting that other standards in the BS EN 12390 series, such as BS EN 12390-12, may address the determination of CO2 concentration or carbonation resistance in concrete through different testing methods specifically designed for that purpose.

The climatic chamber with CO2 control developed by Wewon Environmental Chambers Co., Ltd. meet the test standdard of BS EN 12390-2 and DIN EN 12390-2 Testing Hardened Concrete – Part 2: Making and Curing Specimens for Strength Tests; German and English Version prEN 12390-2:2017. Carbonation testing is an important tool for determining the longevity and durability of building materials. By simulating real-world conditions over multiple cycles, engineers can determine to what extent a material is susceptible to degradation from factors such as CO2 and humidity. In this way, carbonation testing can provide insights into a material’s longterm performance and potential lifecycle costs.

How Is Carbonation Tested Using Climate Chambers? Climate chambers with CO2 control can be used for accurate and repeatable carbonation testing. The chambers provide a controlled environment in which different levels of humidity and CO2 can be used as treatment in order to produce changes in the material. By monitoring these changes over multiple cycles, researchers are able to determine the extent to which a material may experience degradation due to its exposure to certain conditions.

What are the Benefits of a Climate Chamber with CO2 Control? The most obvious benefit of a climate chamber with CO2 control is the ability to replicate exact environmental conditions, meaning that results are much more repeatable and accurate. Another advantage of using such chambers is the ability to accurately control both temperature and humidity levels, as well as CO2 quantities. Moreover, these climate chambers can provide precise data logging measures that can help researchers gain a better understanding of specific materials used in building projects.
