List of Experiments
| Exp. | Title | Description / Objective |
| 1 | Setting Time of Cement | Determine initial and final setting times of ordinary Portland cement using Vicat's apparatus; relate setting behaviour to hydration chemistry and w/c ratio |
| 2 | Consistency of Cement Paste | Determine the standard consistency of cement paste using Vicat's apparatus; understand its significance in mix design and workability |
| 3 | Corrosion of Iron – Effect of Electrolyte | Study the effect of NaCl, H2SO4, and distilled water on the rate of corrosion of iron nails; measure weight loss over time; relate to chloride-induced corrosion in concrete |
| 4 | Effectiveness of Corrosion Inhibitors | Study the inhibition of mild steel corrosion in HCl using organic inhibitors (e.g. aniline, thiourea); calculate inhibition efficiency; relate to protective coatings on rebars |
| 5 | Determination of pH, TDS, and Conductivity of Water | Measure pH, total dissolved solids (TDS), and electrical conductivity of given water samples using electrode meters; classify water suitability for construction use |
| 6 | Determination of Total Hardness of Water | Determine temporary and permanent hardness of water by EDTA titration method; relate to scaling in water pipes and quality of mixing water for concrete |
| 7 | Estimation of Chloride Content in Water | Determine chloride ion concentration in water samples by Mohr's method (argentometric titration); assess suitability of water for RCC construction |
| 8 | Fineness of Cement by Sieve Analysis | Determine fineness of cement using 90-micron IS sieve; relate fineness to rate of hydration, strength development, and heat of hydration in concrete |
| 9 | Determination of Specific Gravity of Cement | Determine specific gravity of cement using Le Chatelier's flask and kerosene; relate to concrete mix design calculations |
| 10 | Viscosity of Adhesive / Polymer Coating | Measure viscosity of given adhesive or polymer coating solution using Ostwald viscometer at different concentrations; relate to workability and adhesion in structural bonding applications |
| 11 | Tensile Strength of Adhesive Bond | Prepare lap-joint specimens bonded with epoxy or polymer adhesive; measure tensile shear strength; compare with reference standard; relate to FRP bonding in structural retrofitting |
| 12 | Determination of COD of Waste Water | Determine Chemical Oxygen Demand (COD) of a given wastewater sample by dichromate reflux method; assess organic pollution load relevant to construction site wastewater management |

Teaching-Learning Methodology
Each laboratory session begins with a 10-minute pre-lab discussion connecting the experiment to the corresponding theory unit. Students record aim, principle, apparatus, chemicals, procedure, observation table, calculations, result, and inference in the laboratory record book. Post-lab discussion relates experimental findings to real-world engineering applications in the respective stream. Students maintain a laboratory record book assessed for viva, record, and day-to-day performance.
