摘要

本研究的目的是(1)分析添加椰壳废料后新拌混凝土的特性(2)分析添加椰壳废料后混凝土的抗压强度。混凝土的研究地点在东南苏拉威西省政府水资源和社区发展部建设实验室进行。样品24个,尺寸为30cm × 15cm,柱状,成分分别为0%、5%、10%、15%椰壳废料。然后在7、14和28天的时候进行抗压强度测试。以质量计划为f’c 20 MPa的抗压强度试验为例,28天试验中,添加量为0%为23.71 MPa,添加量为5%为20.59 MPa,添加量为10%为19.97 MPa,添加量为15%为13.53 MPa。椰子壳作为粗骨料的替代品,在质量为20mpa时,只能在粗骨料用量的10%以下使用。

Testing the Compressive Strength of Concrete with the Addition of Coconut Shell Waste
The purpose of this study was to (1) analyze the characteristics of fresh concrete with the addition of coconut shell waste (2) to analyze the compressive strength of concrete with the addition of coconut shell. The research location for making concrete was carried out at the Laboratory of the construction of the water resources and community development department of the Southeast Sulawesi provincial government. There were 24 specimens printed in the form of a cylinder with dimensions of 30cm x 15cm with the composition of adding 0%, 5%, 10%, and 15% coconut shell waste. Which was then tested for compressive strength at the age of 7, 14, and 28 days. Based on the compressive strength test with a quality plan of f'c 20 MPa, on the 28 day test with the addition of 0% is 23.71 MPa, the addition of 5% is 20.59 MPa, the addition of 10% is 19.97 MPa, and an additional 15% is 13.53 MPa. Coconut shell as a substitute for coarse aggregate for quality f'c 20 MPa can only be used under 10% of the amount of coarse aggregate.
