Utilizing Limestone Waste Factory Cement Using Fiber Palm Oil Fiber as Power Forming mush on Light Brick

Abstract

Lighting of limestone from PT Semen Padang Indarung streat Padang has been done by variation of the addition of empty palm oil bunches to form pores derived from palm oil plantation waste in Pematang Siantar area with mixed percentage of 5%, 10 %, 15%, 20% and 25%. The duration of drying varies from 1 week, 2 weeks, 3 weeks, 4 weeks and 5 weeks. Sintering temperatures are made varying from 700°C, 800°C and 900°C. The sample dimension is made in the form of beams and cylinders. The parameters tested were shrinkage of fire, density, porosity, water absorption, compressive strength and impact strength. The test results showed that optimum results on 85% of Limestone composition and 15% empty palm oil bunches with 4 weeks of sun drying and sintering temperature of 800°C The results obtained are 0.56%, density1.31 g/cm 3 , porosity 26.02%, water absorption 12%, compressive strength 96.39 Kgf / cm 2 and impact strength 26.46 Kgf / cm 2 .
