Concrete Mix Ratio Calculator - Concrete Mix Ratio

Calculate concrete mix ratios (cement, sand, gravel, water) based on concrete grade and total volume needed. SNI standard calculations for construction and civil engineering projects. Supports M15, M20, M25, M30, and custom mix designs with material estimation.

Concrete Mix Ratio

1 : x : y (Cement : Sand : Gravel)

Keterangan:

  • Grade
    Concrete strength (MPa)
  • Cement
    Cement weight (kg)
  • Sand
    Sand volume (m³)
  • Gravel
    Gravel volume (m³)
  • Water
    Water volume (liters)

How to Use

  1. 1

    Select Grade

    Select kekuatan beton yang diinginkan (K225, K250, K300, dst).

  2. 2

    Input Volume

    Enter volume beton yang diperlukan (m³).

  3. 3

    Calculate

    Dapatkan komposisi campuran lengkap.

Contoh Perhitungan

Beton K300

Soal:

Volume 1 m³, Grade K300. Berapa komposisi?

Penyelesaian:
  1. 1.Rasio K300 = 1:1.5:2.8
  2. 2.Semen = 350 kg
  3. 3.Pasir = 0.45 m³
  4. 4.Kerikil = 0.85 m³
Hasil:Semen 350kg, Pasir 0.45m³, Kerikil 0.85m³, Air 175L

Rasio standar K300 is 1:1.5:2.8 with air 0.5 perbandingan semen.

Pertanyaan yang Sering Diajukan (FAQ)

What is grade beton?
Kekuatan tekan beton setelah 28 days, dinyatakan in MPa (N/mm²).
Berapa faktor air-semen?
Umumnya 0.4-0.6, makin rendah makin kuat tapi sulit dikerjakan.
