Laboratory Testing on the Standard Mixed Designed Paving with Bamboo Material as Smooth and Rough Aggregate

Abstract

The use of natural ingredients as a mixture of concrete such as bamboo waste to increase the absorption of paving but still meets the standards of minimum compressive strength. This study aims to obtain the optimum value of bamboo waste substitution in coarse and fine aggregate aggregates based on the standard of minimum paving compressive strength. Test objects measuring 15cm x 15cm x 15cm use substitution of powder mixture and bamboo pieces with a percentage of 10%, 15%, 20% and 25% as many as 5 pcs per percentage and laboratory testing of compressive strength at the age of 28 days is carried out. From the results of the compressive strength test, the average compressive strength of each variation is 10% = 22.16 MPa, 15% = 17.51 MPa, 20% = 15.27 MPa and 25% = 12.72 MPa. Based on the target of minimum compressive strength for paving (17 MPa), the results of mixed substitution are obtained by the percentage of optimum compressive strength of 16% with optimum absorption of 0.21%.
