A small amount of alkali was incorporated into the mixture and subjected to modification by calcination improve latent hydraulicity shield-dried soil (SDS) mixtures for optimum utilisation.The microstructural changes that occur in SDS during hydration after mixing with PC were analysed thermogravimetry, scanning electron microscopy X-ray diffraction.The objective investigate influence modified on both products structure pastes.The investigation yielded following findings: The study involved preparing a slurry composed 30 % 70 PC, it found highest occurred when NaOH dosage 0.05 %.After 28-days, samples reached compressive strength 79.36 MPa.While reference specimen solely 86.12 MPa.The addition altered surface SDS, affecting its amorphous characteristics enhancing hydraulicity.The alkali-modified readily reacted calcium hydroxide (CH), product resulting additional formation monosulfate hydrated silicate, which improved paste.However, excessive potentially degrade pastes.
