  The paper presents the influence of two fractions (M1 and M2) of aluminosilicate microspheres in the amount of 0.0%, 1.5%, 3.5%, and 5% as a cement substitute on the early heat of hydration of cement mortars assessed by isothermal calorimetry (IC). The study results showed a higher accumulated heat of hydration for cement mortars with 1.5% of the test material for both grain fractions. In turn, mortars with 3.5% and 5% of smaller...

  This subject of the work is the study of selected properties of cement mortars containing two fractions of aluminosilicate microspheres with grain size in the range of 125 to 250 μm and from 250 to 500 μm. Mortar mixtures with ordinary Portland cement (OPC 42.5R) and three substitution rates of cement by microspheres, 1.5%, 3.5%, and 5.0%, were investigated....
