%T Studi Pengaruh Variasi Suhu Kalsinasi Terhadap Kandungan Batu Kapur Parengan Kabupaten Tuban %V 9 %J BEARING : Jurnal Penelitian dan Kajian Teknik Sipil %X The industrial and construction worlds utilize a lot of limestone from nature as a material. Easy utilization and abundant materials make limestone always attractive. Conventional processing is still a way to utilize limestone. In order to support more optimal utilization, laboratory-scale analysis is carried out. X-Ray Fluorescence (XRF) is an initial analysis to determine the limestone content. Calcination is carried out on limestone with the aim of changing its properties to be reactive with a planned calcination degree of 500˚C. The original condition and conventional heating are used as samples as a comparison to the calcined limestone. The test results showed an increase in CaO content of 3% compared to the initial condition of the limestone, while SiO2 increased by 42% %I BEARING : Jurnal Penelitian dan Kajian Teknik Sipil %L repository4806 %A Santoso (2026) Toni Budi Santoso %A Ikhwan M.
