Chemical-composition-based design of self-leveling geopolymer stabilized soil: Performance optimization and engineering design.

(1) When sodium silicate with a modulus of 2.0 is adjusted to different moduli (1.2, 1.4, 1.6, 1.8, 2.0), the compressive strength of the mortar decreases as the adjusted modulus increases from 1.2 to 2.0, while the flexural strength shows an increasing trend, but the magnitude is relatively small.

(2) When sodium silicate with different moduli (2.0, 2.3, 2.8, 3.0, 3.4) is adjusted to a modulus of 1.2, both the compressive and flexural strengths of the mortar exhibit a decreasing trend as the unadjusted modulus of sodium silicate increases.
