ABOUT US

Concrete is a key material that is widely using in the construction field. Our laboratory is studying the potential cementitious materials that can be applied to actual structures in terms of durable and sustainable materials.

Our research team is usually carrying out the durability assessment of concrete, development of eco-friendly construction materials, improvement of concrete quality using novel additive materials. Also, we analyze and identify problems arising from the material properties of concrete through theory study and experimental methods. Moreover, in order to meet the trend of the 4th industrial revolution, we are challenging to combine with machine learning technology and concrete material research.

We aim to be the leading laboratory in concrete research by extracting the best results and combining concrete research with various techniques.

Research Interests of Our Lab

We are carried out many fields of concrete material researches

What we did : 

- Self-healing concrete with various materials using a granulating technique

- Self-cleaning concrete using titanium dioxide

- Eco-friendly and durability: making some construction material using waste materials

- Energy-saving concrete with PCM material

- Magnesia cementitious material as an urgent maintenance material

- Carbon dioxide capturing concrete and recovery of alkalinity of concrete

And we are mainly carrying out now :

- Thermal conductivity concrete + Estimation of the parameters of thermal conductivity analysis with Artificial Neural Network

- Developing a fire-resistance fine aggregate using PCM

We are always trying to advance the concrete technology

Self-healing concrete

Self-healing concrete is a concept of healing the cracks on the concrete itself. It was a very hot topic in the early 2000s. Our lab researched self-healing concrete with granulated healing materials. If you want to study self-healing concrete, you can study in our lab with our techniques and know-how.

 

Self-cleaning concrete

Self-cleaning concrete can automatically clean its surface after irradiation with an external energy source like sun light. This research exploits photocatalysis for enhancing the aesthetic look of concrete.

 

Eco-friendly and durability

This concept is a kind of research on the enhancement of concrete durability for the major deterioration factors of concrete such as leaching, chloride attack, carbonation, and acid attack. We can predict the service life of concrete from this experiment and this concept is a kind of sustainable research.

Eco-friendly concrete research is the development of supplementary cementitious materials using industrial by-products in order to reduce the usage of cement. You can study this topic in our lab.

 

Energy saving concrete

This concrete integrates the coating techniques on aggregates carrying phase change material (PCM) and thermal conducting material. We are performing research on this aggregate very actively, and now we are developing a fine aggregate using PCM which has the same principle.

 

Magnesia cementitious material

This research is carrying out worldwide as a part of reducing the usage of cement. It is difficult to get the strength as same as concrete, however, the technique is developing continuously. 

Our lab focus on not only getting the strength close to concrete but also increasing durability.

 

Deep learning with concrete

In case of time-series concrete experiment, the quantity of data is massive. Therefore, we break away the linear time-series analysis such as ARIMA, etc., and start a new analysis trend using deep-learning. Besides analyzing the time-series data, this research aims to enhance the maintenance technology of concrete using real-time object detection method based on deep learning.

 

Complex deterioration of concrete

The deterioration of concrete usually occurs with at least 2 factors such as chloride penetration with freezing and thawing or carbonation with chloride penetration.

Nowadays, many researchers focus on this phenomena, and our lab also preparing and trying to demonstrate complex deterioration behavior.

 

Carbon dioxide capturing concrete

Concrete carbonation consumes the carbon dioxide in the air, and some researches indicate concrete can capture the carbon dioxide. However, Alkaline is the main problem when capturing carbon dioxide.

So, our lab finds a way of capturing carbon dioxide with alkaline recovery. If alkaline can maintain or recover during carbonating state, concrete can capture more carbon dioxide than normal concrete and can contribute to reducing carbon dioxide using concrete.

 

Thermal conductivity concrete

The threat of black ice on highway or road is critical to our safety. Therefore, we need concrete which has a high thermal conductivity. The usual thermal conductivity of concrete is the range of 1.4~1.7. But our research team aims to enhance the thermal conductivity upper than 3.0. In particular, our research team does not use some expensive materials such as carbon nanotube, graphene, and so on.

We are developing this concrete very actively now.
