Abstract:

Lightweight concrete is concrete with heavy contents m3 of 1,900 kgs, maximum range of how to do to get the weight of the concrete contents of the maximum of 1900 kgs, among others, by using a pumice stone, adding air, and others. Ulin wood is the first-class wood with strong and durable, and resistant ulin wood in various weather. Indonesia's high rice production raises the number of waste from processing paddy rice into one rice husk. This study used waste ulin wood, which comes from renovation building waste, and wood waste ulin wood, which comes from processing crude into ready-made wood, charcoal, and husks rice milling took from around the University campus area Muhammadiyah Kalimantan Timur, ulin wood waste is used instead of the rough aggregate 75% rice husk, and processed into charcoal is a substitute for sand 100%, the biggest cut to ulin wood 20 mm and customized gradations, rice husk burned into charcoal. The test object is created 12 fruit test objects, with plans for a powerful hit of 25 MPa. The weight of the concrete results obtained an average of 1,879 kgs and strong hit at 28 days, gained strong press average 22.81 MPa, from those results do not reach the target despite the strong press plans 25 MPa concrete, but by using these two materials, These would've been categorized lightweight structural concrete.

Keywords:

coarse aggregate, fine aggregate ulin wood husks charcoal, light concrete.
