3D Conditional Generation of Cement Paste Microstructure
This paper is extended from previous one on 2D unconditional generation of cement paste. We proposed a latent diffusion transformer for generating the 3D microstructure of cement paste with different Blaine values, wc ratios, and ages!!! Promising results show great potential of generative AI in replacing the expensive SEM/ CT tests!

Generative AI for cementitious microstructure synthesis
This paper presents my first attempt at using generative AI to synthesize microstructures of cementitious materials. A Denoising Diffusion Probabilistic Model (DDPM) was employed to generate synthetic BSE images of OPC with a water-to-cement ratio (w/c) of 0.4. The generated images closely resemble real BSE images in both statistical and microstructural analyses. I have recently extended this work to the conditional generation of three-dimensional hydrating cementitious microstructures with varying w/c ratios, Blaine values, and curing ages. Stay tuned for further updates!

A Mini-TSTM for Efficient Stress Test
A Mini-TSTM is devised to allow for efficient stress test, which further enanbles comprehensive numerical study on the stress evolution, particularly on the creep-relaxation conversion in the simulation.

Active Learning for Stress Evolution Prediction
An active ensemble learning is constructed to efficiently predict the early-age stress evolution based on a themo-chemo-mechanical model, light gradient boosting model, and gaussian process.
