SIFAT KIMIA DAN FISIK BAHAN UTAMA CONBLOCK RINGAN YANG MENGGUNAKAN AGREGAT SEKAM PADI
Abstract: This research aimed
to assess the properties of main substances used to produce lightweight
composite cement using rice husk as aggregate. Main substances used in this
research consisted of Portland cement tipe I, lime, rice husk and rice husk
ash. Portland cement tipe I, lime and rice husk obtained from local producers
in Makassar, while rice husk ash obtained by burning rice husk conventionally
in kiln drum and subsequently followed by burning in furnace of 1400 Barnsted
Thermolyne Type at temperature 600 oC for 2 hours. Chemical Content of the
substances analyzed by adopted the analysis procedure in SNI 15-2049-2004.
Alkalinity of Portland cement tipe I, silica of rice husk ash and Na2O dan K2O
was categorized as low, while rice husk was categorized as reactive substance.
