Abstract

ABSTRACT: One of the materials most often used for building structural components is concrete. To produce quality concrete, you need to improve the quality of the constituent materials, such as the fineness of the cement and the hardness of the aggregate. Concrete can be made of higher quality by adding additional chemicals such as superplasticizers and fly ash, some of which can replace cement. The main objective of this research is to compare concrete mixtures and determine the compressive strength of concrete that has been added with superplasticizer, as well as to obtain the optimum fly ash content value for the compressive strength of concrete added with superplasticizer of 0.5% with fly ash substitution until it reaches a maximum value of 15%. . The maximum compressive strength of concrete containing a 15% fly ash mixture at 28 days is 388.57 kg/cm2. Based on this research, concrete with a 15% fly ash mixture has a maximum compressive strength of 372.43 kg/cm2, compared to normal 0% concrete of 388.57 kg/cm2, while for a 5% fly ash mixture it is 369.08 kg/cm2, and 371.37 kg/cm2 for 10% fly ash mixed concrete.Keywords: Concrete, Fly ash, Superplasticizer, Compressive Strength, Variations  ABSTRAK: Salah satu material yang paling sering digunakan untuk komponen struktur bangunan adalah beton. Untuk menghasilkan beton yang berkualitas adalah dengan meningkatkan kualitas bahan penyusunnya, seperti kehalusan semen dan kekerasan agregat. Beton dapat dibuat dengan kualitas lebih tinggi dengan menambahkan bahan kimia tambahan seperti superplasticizer dan fly ash yang sebagian dapat menggantikan semen. Tujuan utama penelitian ini adalah untuk membandingkan campuran beton dan mengetahui kuat tekan beton yang telah diberi bahan tambah superplasticizer, serta memperoleh nilai kadar fly ash optimum terhadap kuat tekan beton berbahan tambah superplasticizer sebesar 0,5% dengan subtitusi fly ash sampai mencapai nilai maksimum 15%. Kuat tekan maksimum beton yang mengandung campuran fly ash 15% pada umur 28 hari adalah 388,57 kg/cm2. Berdasarkan penelitian ini, beton dengan campuran fly ash 15% mempunyai kuat tekan maksimum sebesar 372,43 kg/cm2, dibandingkan beton normal 0% sebesar 388,57 kg/cm2, sedangkan untuk campuran fly ash 5% sebesar 369,08 kg/cm2, dan 371,37 kg/cm2 untuk Beton campuran fly ash 10%.Kata kunci: Fly ash, Superplasticizer, Kuat Tekan Beton
