Analisis Pengaruh Serbuk Kayu Sebagai Bahan Tambah Agregat Halus Terhadap Kuat Tekan Beton

Sawdust (serbuk kayu) is the dregs of the production of the timber industry which has not been used optimally. Therefore, in this study, the use of sawdust waste was developed as an additive to fine aggregate in the hope of increasing the compressive strength of concrete and reducing the accumulation of sawdust waste in the community. The main purpose of using sawdust waste is to find out how strong the results of the comparison value obtained by the variation of sawdust concrete are with the compressive strength value of normal concrete. Variations in addition of sawdust used were 0.3% and 0.6%. From the analysis of the average compressive strength that has been carried out when the concrete age reaches 28 days, normal concrete gets a value of 16.55 MPa, 0.3% sawdust variation gets a value of 15.02 MPa and wood powder variation concrete 0, 6% reached a value of 17.42 mpa. The percentage value of the comparison obtained from the compressive strength of normal concrete and 0.3% sawdust substituted concrete decreased by -9.24%, while the percentage value of the compressive strength of normal concrete and 0.6% sawdust substituted concrete increased against compressive strength of 5.26%.
