Modified blended limestone-Portland cement binders: Evaluation of 4 different sodium silicates

One-part blended cements with 65% limestone and 35% Portland cement (PC) were activated by 3–8%wt. of four powdered sodium silicates of different modulus SiO2/Na2O = 1–3.26. Pastes were cured at 20 °C for 180 days in dry and underwater conditions. The use of moduli
