Cos'è il calcolo del calcestruzzo?

Concrete calculation determines the exact volume of concrete needed and the required materials (cement, sand, aggregate) based on the selected mix ratio. Accurate calculations prevent material waste, control costs, and ensure proper project planning.

6 Calculation Modes

Lastra rettangolare

V = L × W × T. Cortili, vialetti, pavimenti.

Lastra Circolare

V = π × r² × T. Patii rotondi, fondazioni.

Colonna

V = π × r² × H. Pilastri, colonne rotonde.

Base

V = L × L × P. Basamenti di fondazione.

Parete

V = L × H × P. Muri in cemento, barriere.

Conversione del volume

Convert between cu ft, cu yd, and m³.

Understanding Mix Ratios

Ratio Cemento Sabbia Aggregato Utilizzo
1:2:4124General construction, foundations
1:1.5:311.53Structural elements, higher strength
1:3:6136Non-structural, mass concrete
1:2:3123Heavy-duty, structural
1:1:2112Maximum strength

Volume Conversions

1 cubic yard = 27 cubic feet

1 cubic foot = 0.0283168 cubic meters

1 cubic yard = 0.764555 cubic meters

Note importanti

  • Add 5–10% extra to account for waste, spillage, and uneven surfaces.
  • Round up cement bags to the nearest whole number when purchasing.
  • I metri cubi sono l'unità standard utilizzata dai fornitori di calcestruzzo preconfezionato negli Stati Uniti.
  • Per i progetti strutturali, consultare un ingegnere autorizzato per la corretta miscelazione e rinforzo.
