Introduction:
One of the most frequently used building materials is concrete, but it is prone to various diseases and failure patterns that can lead to costly repairs and compromised structural integrity. Early detection of concrete issues is critical to prevent severe damage and ensure the safety and longevity of infrastructures. This research proposal outlines the development of an innovative machine learning model that utilizes real-time camera input to automatically recognize concrete diseases and failure patterns on construction sites, thereby empowering construction professionals with rapid and accurate diagnostic capabilities.
Objectives of finding concrete diseases:
The primary objectives of this research are as follows:
Develop an AI-based model capable of recognizing concrete diseases and failure patterns.
Create a comprehensive database of concrete sample photos, labeled with specific diseases, failure patterns, and root causes.Evaluate the model’s performance and accuracy in real-time construction site conditions.
Establish a user-friendly interface for on-site deployment and integration with existing construction workflows.

Methodology:
a. Data Collection:
Gather a diverse dataset of concrete sample photos from various construction sites, capturing different concrete types, environmental conditions, and disease/failure instances.
Collaborate with construction companies to access real-world construction sites and collect high-quality images.
Ensure data privacy and anonymization of sensitive information.
b. Data Preprocessing:
Clean and preprocess the collected data to remove duplicates, irrelevant images, and artifacts.
Label the data with corresponding concrete diseases, failure patterns, and potential causes.
c. Model Development:
Utilize state-of-the-art deep learning architectures for image recognition tasks.
Implement transfer learning techniques to leverage existing pre-trained models for efficient training.
Fine-tune the model using the labeled dataset of concrete images. There are several models for build the model.
K-Nearest Neighbors (K-NN): A simple and effective algorithm that classifies data points based on the majority class of their k-nearest neighbors.
Support Vector Machines (SVM): A powerful supervised learning algorithm used for classification and regression tasks. The goal of SVM is to identify the best hyperplane for classifying data.Logistic Regression: A type of regression that is used to solve binary classification problems. It forecasts the likelihood of an instance belonging to a specific class.
Random Forest: An ensemble learning method for improving accuracy and reducing overfitting by combining multiple decision trees.
Neural Networks: Deep learning models that can be used for various disease recognition tasks, leveraging their ability to learn complex patterns from data.
Decision Trees: To make classification decisions, tree-based models recursively divide data into subsets based on the most discriminative features.
Naive Bayes: A probabilistic classifier based on Bayes’ theorem with strong independence assumptions between features.
Convolutional Neural Networks (CNN): Because of their ability to automatically learn hierarchical features, neural networks are frequently used for image-based disease recognition tasks.
Long Short-Term Memory (LSTM) networks: A type of recurrent neural network (RNN) commonly used for sequence data, such as time-series data or natural language processing tasks related to diseases.
d. Real-Time Integration:
Optimize the model for real-time performance, considering computational efficiency and memory constraints.
Develop an intuitive user interface that allows construction professionals to capture images and obtain instant disease and failure pattern analysis.
Evaluation:
a. Performance Metrics:
Accuracy, Precision, Recall, and F1-score to assess the model’s recognition capabilities.
Inference time to evaluate the real-time feasibility of the system.
b. Validation:
Conduct extensive cross-validation to ensure the model’s robustness and generalization across different construction sites and concrete types.
Collaborate with domain experts to validate the model’s accuracy in detecting real-world concrete issues.
Impact and Applications:
The successful development of this AI-enabled concrete disease and failure pattern recognition system will have significant practical applications and positive impacts:
Early detection of concrete issues will lead to cost savings on maintenance and repairs.
Enhanced safety for infrastructure users due to proactive identification of potential hazards.
Improved construction project timelines by reducing downtime caused by concrete failures.
Valuable insights into the most prevalent concrete issues and their root causes for future improvements in construction practices.
Result:
Our model is still in training. and we need a huge set of data. We did a test on the following models for a trail run. And as you can see, the results are quite good but not satisfactory because we trained this model with only 50 images. But still, this result gives us motivation to take our research further.
