1. Draw 2 schematic diagrams and explain life cycles of gypsum and lime. 2. (i) Draw a typical stress-strain curve of steel tensile test and (ii) explain Young's modulus, yield strength, ultimate strength and ductility of steel. 3. Explain fractional distillation of oil and production of asphalt with the help of schematic drawings. 4. (i) List 4 mineral components of Portland cement (write down their formal name and cement chemistry notation) and (ii) list 3 typical types of mineral admixtures to cement. 5. (i) Regarding fresh concrete, explain the concept of W/C ratio and slump, and (ii) discuss the relationship between the two concepts. 6. Fill the table below, calculate fineness modulus and determine the type of the sand tested. sieve(mm) residue (g) 4.75 2.36 1.18 0.60 0.30 0.15 <0.15 50 80 100 105 75 85 a А 7. Bulk density of a piece of dry sponge (whose dimension is 10 cm x 10 cm x 3 cm) is 0.05 g/cm³. It weighs 300 g when fully soaked with water (water density is 1 g/cm³). Find porosity of the sponge. 8. Required strength grade of concrete is C30, slump required is 20-40mm. Standard deviation of concrete strength (6) is 4 MPa. Constants A=0.46, B=0.07, a=1. Properties of raw materials are as follows: Ordinary cement: fce=47 MPa, p=2400 kg/m³ p=1000 kg/m³, usage 165 kg p=2200 kg/m³, S,=35%, Ws=1% p=2300 kg/m³, W=2% Water: Sand: Crushed stone: Design preliminary mix ratio and working mix ratio.
