Examples
Beton K300
Problem:
Volume 1 m³, Grade K300. Berapa komposisi?
Solution:
- 1.Rasio K300 = 1:1.5:2.8
- 2.Semen = 350 kg
- 3.Pasir = 0.45 m³
- 4.Kerikil = 0.85 m³
Result: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.
Frequently Asked Questions
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.
