Water-cement ratio (w/c) by mass.

cement: f64

Cement content (kg/m³).

water: f64

Water content (kg/m³).

fine_agg: f64

Fine aggregate content (kg/m³).

coarse_agg: f64

Coarse aggregate content (kg/m³).

superplasticiser: f64

Superplasticiser dosage (% bwc).

Air entrainment (%).

slump: f64

Slump (mm).

Implementations

impl ConcreteMixDesign

pub fn new( wc_ratio: f64, cement: f64, fine_agg: f64, coarse_agg: f64, air_content: f64, ) -> Self

Create a standard Normal Portland Cement mix.

pub fn c30_normal_weight() -> Self

Create a typical C30 normal-weight mix (approximate ACI 211 proportioning).

pub fn high_performance() -> Self

Create a high-performance mix with superplasticiser.

pub fn fresh_unit_weight(&self) -> f64

Fresh concrete unit weight (kg/m³), ignoring air.

pub fn abrams_strength(&self) -> f64

Estimated 28-day compressive strength (MPa) via Abrams’ law. fc = A / B^(w/c), with A=96 MPa, B=8.6 for OPC.

pub fn paste_volume(&self) -> f64

Volume of paste (m³/m³ concrete).

pub fn aggregate_cement_ratio(&self) -> f64

Aggregate-cement ratio by mass.

pub fn meets_durability_wc_limit(&self, max_wc: f64) -> bool

Check Duff Abrams water-cement ratio limit for durability (≤ 0.50 for exposure class C2).

pub fn combined_fineness_modulus(&self, fm_fine: f64, fm_coarse: f64) -> f64

Fineness modulus of combined aggregate (simplified weighted average). fm_fine = fineness modulus of fine agg, fm_coarse = coarse.
