ACI KUET Student Chapter

Inside KUET Concrete Laboratory

Explore the state-of-the-art materials testing, hydraulic crushing, and non-destructive evaluation facility driving advanced concrete research at the Department of Civil Engineering, KUET.

Experimental Research Hub

Where Advanced Concrete Science Meets Hands-on Engineering

The Concrete and Materials Testing Laboratory of the Department of Civil Engineering at KUET is the primary experimental backbone for our undergraduate research, national competition prototyping, and industry consultancy verification.

Operating under rigorous ASTM International and British Standard (BS/EN) testing protocols, our chapter members gain direct access to hydraulic universal testing frames, ultrasonic integrity scanners, and precision micro-aggregate sieving apparatus.

Primary Laboratory Testing Equipment

Precision instruments utilized during ACI student chapter mix trials and competition sample preparation

Compressive & Flexural

Digital 2000 kN Universal Testing Machine (UTM)

Equipped with digital load-cell readout and micro-controlled hydraulic pacing. Performs standard compressive crushing of 100x200mm and 150x300mm concrete cylinders (ASTM C39), flexural beam third-point loading (ASTM C78), and splitting tension (ASTM C496).

Rheology & Workability

ASTM Standard Slump Cone & Flow Table

Standard inverted metallic cone (ASTM C143) with bullet-nosed tamping rod for fresh concrete slump verification. Accompanied by circular flow table rig to measure slump-flow spread for Self-Consolidating Concrete (SCC) per ASTM C1611.

Hydration & Curing

Thermostatically Controlled Curing Tanks

Continuous submerged lime-saturated water curing environment operating at standard 23.0 ± 2.0 °C. Houses over 250 test specimens concurrently for standardized 7, 14, 28, and 56-day compressive strength maturity benchmarks.

Non-Destructive Testing (NDT)

Ultrasonic Pulse Velocity (UPV) Pundit Rig

High-frequency piezoelectric transducers (54 kHz) measuring ultrasonic wave transit times across structural concrete members. Diagnoses internal honeycombing, void fraction, crack depth, and dynamic elastic modulus (ASTM C597).

Aggregate Characterization

Motorized Sieve Shakers & Pycnometers

Standard sieve stacks conforming to ASTM C136 (from 1.5-inch down to No. 200). Generates particle size distribution curves, Fineness Modulus (FM), aggregate bulk specific gravity (SSD), and absorption capacity vital for ACI 211.1 calculations.

Micro-Batching

High-Shear Pan Mixer & Compaction Table

Laboratory planetary pan mixer enabling uniform dispersion of superplasticizers, silica fume, fly ash, and structural fibers. High-frequency vibrating table ensures complete specimen consolidation without segregation.

Standard Experimental Testing Cycle

From aggregate moisture correction to high-speed digital crushing data logging

1. Proportioning

Weighing cement, aggregates, water, and chemical admixtures with moisture compensation.

2. Batch Mixing

Sequential charging: coarse aggregate, water, cement, and high-range water reducers.

3. Slump & Casting

Fresh state testing (slump, unit weight, air content) followed by 3-layer cylinder rodding.

4. Moist Curing

24-hour demolding followed by immediate submerged curing at 23°C until test maturity.

5. UTM Crushing

Sulfur or neoprene capping and compressive loading at 0.25 ± 0.05 MPa/sec to fracture.

Safety & Compliance

Laboratory Operating Standards

All chapter members and student researchers working inside the concrete lab must strictly adhere to departmental safety guidelines:

  • Mandatory Personal Protective Equipment (PPE): Safety boots, gloves, and impact goggles.
  • Complete equipment cleaning and pan mixer wash-out immediately after casting.
  • Digital logbook registration of all specimen dimensions and 28-day target grades.
