Perbandingan Air dan Semen pada Beton

ternyata, jika perbandingan air dan semen berdasarkan berat= 50% (berdasarkan berat sering digunakan pada perhitungan ready mix), maka perbandingannya berdasarkan volume=…..? (berdasarkan volume sering digunakan di lapangan/ site mix)

Jawab:

BJ air= 1000kg/m3

BJ semen= 3100kg/m3

Maka, perbandingan berdasarkan volume

= prosentase x (BJ Semen/ BJ air)

= 50%x3100/1000

= 155% = 1.55 kali
