Effects of Cenospheres on Different Compositions of Concrete
Students' Science Conference 2019 2019
Jānis Beķers, Elīna Barone

Cenospheres are light, waterproof alum-silicate spheres. The direction of the re-search is the cenospheres as component of various concrete 0%, 30%, 40%, 50% by volume. Depending on the properties of the desired cement type and mixing ingredients with water and superplasticizer - concrete properties are experimental-ly researched immediately or after 3 days. To determine how much the increase of surface adhesion area after grinding the particles of the cenospheres affects the resulting samples, grinding mill or disintegrator were used to grind the parti-cles. The aim of the research is to obtain scientifically based data about the crushed cenospheres, depending on the time of mixing (right after the milling process or after 3 days of delay) for the impact on quality of concrete by differ-ent composition of cement – CEM II, Aalborg White and Gorkal 70. It is predict-able that the cenosphere additive increases concrete porosity, reduce compressive strength and density. An optical microscope examines compressed samples that shows adhesion properties of spheres and concrete. These concrete materials can be used as a lightweight concrete material for thermal insulation as slabs or spe-cial walls.
