| Summary: | The paper introduces the properties of cement mortars with hollow glass microspheres for wells of Tomsk region. The author has considered porosity and permeability of cement stone. Porosity of cement stone was determined based on the method of A.G. Perekhozhentsev. The cement matrix porosity as well as porosity of cement stone were defined. Based on G.I. Gorchakov classification the author estimated gel, capillary and air porosity of cement matrix and light-weight cement stone depending on consumption of hollow glass microspheres. The author constructed a diagram for the cement stone samples after the obtained sorption isotherms have been processed. The analysis of these diagrams allows making the conclusion that stone compact structure is formed at cement stone hardening at pressures; introduction of hollow glass microspheres into the structure of cement mortars decreases stone vapor permeability. |
