Secara sederhana, beton dibentuk oleh pengerasan campuran antara semen, air, agregat halus (pasir), dan agregat kasar (batu pecah atau kerikil). Kadang-kadang ditambah bahan lain untuk memperbaiki kualitas beton. Perkembangan sekarang ini, beton merupakan bahan yang paling banyak dipakai pada pembangunan dalam bidang teknik sipil, baik pada bangunan gedung, jembatan, bendung, maupun konstruksi lain. Sifat dari bahan beton, yaitu sangat kuat untuk menahan tekan, tetapi tidak kuat (lemah) untuk menahan tarik. Metode yang digunakan dala desain campuran beton menggunakan SNI 03-2834-2000. Penelitian ini dilakukan eksperimen di laboratorium. Tujuan dari penelitian ini untuk mengetahui nilai kuat tekan beton normal, nilai kuat tekan beton dengan penambahan abu batu, penambahan semen mortar utama type 400 dan kombinasi penambahan abu batu dan semen mortar utama type 400. Nilai kuat tekan beton direncanakan standar 25 MPa. Kesimpulan yang dihasilkan adalah nilai kuat tekan beton normal sebesar 25,16 MPa, kuat tekan beton terbesar dengan penambahan abu batu 6 % sebesar 26,49 MPa, kuat tekan beton terbesar dengan penambahan semen mortar utama type 400 6% sebesar 27,57 MPa dan kuat tekan beton dengan kombinasi penambahan abu batu dan semen mortar utama type 400 6% sebesar 27,97 MPa. Sedangkan model hubungan regresi linier sederhana mempunyai hubungan yang kaut antara variabel bebas (X) dengan variaber erikat (Y) dengan koefisien determinasinya (R) lebih besar dari 0,950 untuk seluruh nilai kuat tekan. In simple terms, concrete is formed by hardening a mixture of cement, water, fine aggregate (sand), and coarse aggregate (crushed stone or gravel). Sometimes other ingredients are added to improve the quality of the concrete. Current developments, concrete is the most widely used material in construction in the field of civil engineering, both in buildings, bridges, weirs, and other constructions. The nature of the concrete material, which is very strong to withstand compression, but not strong (weak) to withstand tension. The method used in the design of concrete mix using SNI 03-2834-2000. This research was conducted experimentally in the laboratory. The purpose of this study was to determine the value of the compressive strength of normal concrete, the value of the compressive strength of concrete with the addition of stone ash, the addition of the main cement mortar type 400 and the combination of adding stone ash and the main cement mortar type 400. The compressive strength value of the concrete is planned to be 25 MPa standard. The conclusion is that the compressive strength of normal concrete is 25.16 MPa, the greatest compressive strength of concrete with the addition of 6% stone ash is 26.49 MPa, the greatest compressive strength of concrete with the addition of cement mortar type 400 6% is 27.57 MPa and The compressive strength of concrete with a combination of the addition of stone ash and the main cement mortar type 400 6% is 27.97 MPa. While the simple linear regression model has a strong relationship between the independent variable (X) and the bound variable (Y) with the coefficient of determination (R2) greater than 0.950 for all compressive strength values.
