Abstract
This study aims to determine the effect of rice husk as a source of substitute fuel on the manufacture of cement at the industry scale. The parameters tested include the physical properties of the cement consisting of the Blain fineness test, false set, cement setting time, and mortar compressive strength at 3, 7, and 28 days. The average values for the results of these tests on cement produced using rice husks as a substitute fuel were 380 m2/kg, 81%, 132 minutes, 253 minutes, and 225, 298, and 379 kg/cm2, respectively. Based on the test results, we have shown that rice husk ash has a good effect on the characteristics of cement type I which still meet the standards of SNI-2049-2015.
Highlights
Rice husk is a waste obtained from the process of rice production and is widely produced by countries that consume rice as a staple food
This study aims to determine the effect of rice husk usage as a substitute fuel in the cement industry on the physical properties of Portland Pozzoland Cement
The physical properties of the cement tested include the fineness, false set, initial and final setting time, and the compressive strength of mortar at an age of 3, 7, and 28 days based on the SNI (Indonesia National Standard) 2049-2015 [16] standard
Summary
Rice husk is a waste obtained from the process of rice production and is widely produced by countries that consume rice as a staple food. These countries include those located in Southeast Asia such as Indonesia, Malaysia, Thailand, Vietnam, and Myanmar. Rice production can be done three times a year, which is an advantage for the use of rice husk as renewable fuel. It is currently used on a small scale as fuel for the production of bricks and tile
