Usage

Example: concrete mix design (Indian Standards)

The example below shows how to create a ConcreteMixDesign, compute the mix and print the results.

from civilutils.indian_standards.concrete import *
from pprint import pprint

design = ConcreteMixDesign(
    concrete_grade=ConcreteGrade.M40,
    maximum_nominal_size=MaximumNominalSize.SIZE_20,
    slump_mm=100.0,
    is_pumpable=True,
    exposure_condition=ExposureCondition.SEVERE,
    specific_gravities=[
        SpecificGravity(Materials.CEMENT, 3.16),
        SpecificGravity(Materials.FINE_AGGREGATE, 2.74),
        SpecificGravity(Materials.COARSE_AGGREGATE, 2.74),
        SpecificGravity(Materials.ADMIXTURE, 1.145),
        SpecificGravity(Materials.WATER, 1.00),
    ],
    chemical_admixture=ChemicalAdmixture.SUPERPLASTICIZER,
    chemical_admixture_percentage=29.0,
    coarse_aggregate_type=CoarseAggregateType.CRUSHED_ANGULAR,
    fine_aggregate_zone=FineAggregateZone.ZONE_I,
    fine_aggregate_water_absorption=0.1,
    coarse_aggregate_water_absorption=0.05
)

# The following call prints the computed mix when display_result=True:
_ = design.compute_mix_design(display_result=True)

# If you prefer to capture the result (no automatic printing), disable display_result:
# result = design.compute_mix_design(display_result=False)
# pprint(result)

Notes

• Adjust input parameters to match your materials and site conditions.

• Use pprint(result) to inspect the returned structure when you capture the result.
