TFM (version 0.5.2)

concrete: Concrete Mixture and Compressive Strength Dataset A dataset that includes the proportions of concrete ingredients (such as cement, slag, fly ash, water, superplasticizer, and aggregates) as well as the mechanical and workability properties (slump, flow, and 28-day compressive strength) of high-performance concrete (HPC).

Description

Concrete Mixture and Compressive Strength Dataset

A dataset that includes the proportions of concrete ingredients (such as cement, slag, fly ash, water, superplasticizer, and aggregates) as well as the mechanical and workability properties (slump, flow, and 28-day compressive strength) of high-performance concrete (HPC).

Usage

concrete

Format

A data frame with 103 observations and 10 variables:

Cement

The mass of Portland cement. Primary binder providing compressive strength through hydration.

Slag

The mass of blast furnace slag. Supplementary cementitious material (SCM) that reduces hydration heat and enhances durability.

Fly.ash

The mass of fly ash. SCM from coal combustion that improves workability and reduces cement usage.

Water

The mass of mixing water. Essential for cement hydration; water-to-binder ratio determines strength and workability.

SP

The mass of superplasticizer. Chemical admixture that enhances workability while reducing water content.

Coarse.Aggr.

The mass of coarse aggregate (e.g., crushed stone). Provides structural rigidity and volume stability.

Fine.Aggr.

The mass of fine aggregate (e.g., river sand). Fills voids between coarse aggregates for optimal particle packing.

SLUMP.cm.

Concrete slump in cm. Key workability metric; higher values indicate greater flowability.

FLOW.cm.

Concrete flow diameter in cm. Supplementary workability metric for self-consolidating concretes.

Compressive.Strength..28.day..Mpa.

28-day compressive strength in MPa. Critical mechanical property measured after standard curing.
