Abstract

Ye'elimite-larnite rocks in the Hatrurim formation of the Negev Desert, Israel, are natural analogs of belite sulfoaluminate (BSA) cement clinkers. They have been produced by ultrahigh-temperature combustion metamorphism at ambient pressure of a calcareous sedimentary precursor. Their mineralogy consists of 35-50 vol% β-Ca₂SiO₄, 15-20 vol% ye'elimite, 7-15 vol% ferrites, and 15-20 vol% fluorapatite and/or fluorellestadite. A few grains of hatrurite (Ca₃SiO₅) and α'-Ca₂SiO₄ have been observed as well. The composition of α'- and β-Ca₂SiO₄ polymorphs by EPMA are near Ca_1.96-1.98Na_0.01-0.02 Si_0.96P_0.03Al_0.01O₄, whereas ye'elimite has an approximate composition by EPMA of Ca_3.99Mg_0.02Ba_0.01 Na_0.02K_0.02Al_5.73Fe^{3 +}_0.16Si_0.10S_0.97P_0.02O₁₆. The Al content of brownmillerite Ca₂(Fe_1-xAl_x)₂O₅ ranges from x = 0.20-0.27. Fe-analog of shulamitite (Ca₃Fe₂TiO₈) contains up to 15.1 wt% TiO₂. Ye'elimite-larnite rocks were derived from chalky sediments by burning of combustible gas with a T_max at 1200-1350 °C. The mineral content, microstructure, and texture/fabric of the ye'elimite-larnite rocks imply that chalky and/or marly sediments with randomly distributed clay, phosphorite, and gypsum may be utilized as cheap naturally homogenized and pulverized mixtures for industrial production of BSA cement clinker, as an environment-friendly alternative to ordinary Portland cement (OPC).
