Comparison of Cellular Lightweight Concrete With Addition of Palm Oil Midribs

Riau Province, Indonesia, has oil palm plantations that continue. Based on statistical data (BPS Indonesia, 2017) in 2016 the area of oil palm plantations in Riau province was 2,430,500 hectares and the potential for large oil palm midrib waste. In order for waste not to cause problems, the waste must be utilized, one of them added
as a mixture of CLC. The purpose of this study was to find a mixture of ingredients made from CLC (Cellular Lightweight Concrete) fibers using materials added to oil
palm midribs. The assessment of product feasibility was determined based on the compressive strength, water absorption and density of the CLC products produced by
the fiber. The study was presented using a descriptive method. The research conducted is quantitative research using experimental approaches and laboratory research. The findings of this study are that the best addition of oil palm midribs is 2.5% of the weight of cement. The conclusion is the best addition of oil palm midribs
in the CLC job mix is 2.5% of the weight of cement with an average compressive strength of 44.60 kg/cm2 at 28 days; The average water absorption value at 28 days is
10.94%; The average density value at 28 days is 1.33 gr/cm3; the job mix consists of 480 kg of cement; 720 kg of sand; 207.5 liters of water mortar; 44 liters of air foam agent; 2.0 liters of foam agent and palm oil midribs 2.5% of the weight of cement.
