The use of calcined diatomite as an additive to geopolymeric materials “2279

HIGHLIGHTS

SUMMARY

    This paper presents a comparison of the properties of geopolymers based on lime fly ash from an incinerator in Belchatow and sand, modified with different contents of diatomite dust-10%,15%, and 30% by weight. The studies were conducted on non-calcined and calcined diatomite dust at 650 ◦ C. Table 1 shows the results of the particle size distribution for raw diatomite and fly ash dust. O5 silicon formula oxide phase increased non-calcined diatomite dust had a higher percentage of phases, such as kaolinite (about 49%) and aluminum oxide (0.5%), in its . . .
