• Brickwork Terminology – Meaning of “Frog” in a Standard Modular Brick In building construction practice, the term “frog” refers to which feature provided on a brick to improve bedding and bond with mortar?
• Road Aggregates – Minimum Coefficient of Hardness for Wearing Courses For stones intended for use in road work (e.g., wearing course metal), the coefficient of hardness should be greater than which minimum value to ensure adequate resistance to abrasion and attrition under traffic?
• Bituminous Products – Typical Use of Bitumen Felt in Building Construction On building sites, factory-made bitumen felt sheets are commonly used for which protective functions in walls and roofs?
• Rock-Forming Minerals – Source of Chlorite (Green, Micaceous Mineral) Chlorite, a common green phyllosilicate in low-grade metamorphic and altered igneous rocks, is mainly produced by the decomposition/alteration of which ferromagnesian minerals?
• Aggregates for Concrete – Name of the Index Expressing Relative Sizes Across Coarse and Fine Fractions Which index number, obtained by summing cumulative percentage retained on a standard sieve series and dividing by 100, expresses the overall coarseness/fineness of combined aggregates?
• Geology for Engineers – Limestones as a Rock Class Limestones encountered in building stone quarries and cement raw mixes are generally classified as which type(s) of rocks based on their origin and structure?
• Stone Testing – Purpose of Dorry’s Testing Machine In standard laboratory evaluation of building stones, the Dorry’s testing machine is specifically used to determine which property relevant to road and floor stones?
• Painting Practice – Typical Composition of an Oil-Based Priming Coat for New Work Which of the following compositions correctly represents a traditional priming coat formulation used on absorbent building surfaces before finishing coats?
• Brick Anatomy – Usual Location of the Frog on a Standard Brick Considering how bricks are moulded and the purpose of the mortar key, on which face of a standard brick is the frog (the rectangular depression) normally provided?
• Igneous Petrology – Origin of Granite Rich in Quartz and Feldspar Granite used as a durable building stone is characteristically composed of quartz and feldspar with mica/other accessories. From which rock class is such granite obtained based on its mode of formation?
• In blast-furnace ironmaking and basic smelting chemistry, identify the correct chronological set of reactions driven by the combustion of fuel inside the furnace. Choose the most comprehensive statement that reflects what actually happens to CO2, CO, and iron oxides during smelting.
• In brickwork detailing for buildings, a bullnose brick is a special unit with a rounded arris used at exposed edges. Identify where a bullnose brick is generally not used in standard practice.
• For common soda–lime window glass used in buildings and glazing, what is the typical percentage range of silica (SiO2) in its composition? Select the most appropriate range widely cited in practice.
• In foundry and ferrous metallurgy practice, select the correct statements about casting sound test, cupola usage, and hot-shortness (red-short) in iron. Choose the most comprehensive correct option.
