การศึกษาการชดเชยค่าหดตัวของวัสดุอัคลาไลน์จากเถ้าลอยแคลเซียมสูงด้วยสารผสมเพิ่มที่ขยายตัว : A study on shrinkage compensation of alkali-activated high calcium fly ash with expanding admixture

1)To study on compressive strength of alkali-activated high calcium fly ash mortar with expanding admixture. 2)To study on shrinkage compensation of alkali-activated high calcium fly ash mortar with expanding admixture. Expected shrinkage value of alkali-activated high calcium fly ash mortar with expanding admixture is approximately 1000 . 3)To study on microstructure of alkali-activated high calcium fly ash paste with expanding admixture by using Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR) to understand the reaction products of alkali-activated high calcium fly ash with expanding admixture.
