The process of mixing clay, water & other ingredients to make brick is known as: Kneading
Advantage of a clamp compared to a kiln for burning bricks is: It has less initial cost
The internal size of mould used in brick preparation is: Greater than size of fully burnt brick
Pug mill is used for: Preparation Of Clay
Bricks used for lining of furnaces: Refractory Bricks
The frog of brick in a brick masonry is generally kept on: Top Face
Number of bricks required for one cubic meter of brick masonry is: 500
Glazing is used to make earthenware: Impervious
Quick lime is: Calcium Oxide
Quick lime is: Slow in setting & Rapid in slacking
Hydraulic lime is obtained by: Burning of kankar
The main constituent which imparts hydraulicity to hydraulic lime is: Clay
The main ingredients of Portland Cement are: Lime & Silica
The constituent of cement which is responsible for initial setting of cement is: Tricalcium Aluminate
The initial setting time for ordinary Portland cement as per IS specifications should not be less than: 30 minutes
The final setting time for ordinary Portland cement as per IS specifications should not be less than: 10 hours
For testing compressive strength of cement, the size of cube used is: 50mm
The normal consistency of ordinary Portland cement is about: 30%
Early attainment of strength in rapid hardening cement is mainly due to: Finer Grinding
After Storage, the strength of cement: Decreases
According to IS specifications, the compressive strength of ordinary Portland cement after three days should not be less than: 16 MPa
Addition of pozzolana to ordinary Portland cement increases: Shrinkage
Gypsum consists of: CaSO4 & H2O
For testing compressive and tensile strength of cement, the cement mortar is made by mixing cement and standard sand in the proportions of: 1:3
The slump recommended for mass concrete is about: 25 mm to 50 mm
With increase in moisture content, the bulking of sand: first increases to a certain maximum value and then decreases
Which cement is suitable for use in massive concrete structures such as large dams: Low Heat Cement
Proper amount of entrained air in concrete results in: Better Workability & Better resistance to freezing & thawing
The most common admixture which is used to accelerate the initial set of cement is: Calcium Chloride
The maximum quantity of calcium chloride used as an accelerator in cement in percentage by weight of cement is: 2
The basic purpose of a retarder in concrete is: To increase the initial setting time of cement paste in concrete
Cement which contains maximum percentage of dicalcium silicate: Low Heat Cement
Most commonly used retarder in cement is: Gypsum
Three basic raw materials which are needed in large quantities for production of steel are: iron ore, coal & lime stone
Compared to mild steel, cast iron has: High Compressive Strength & Low tensile Strength
Which gradient exerts maximum influence on properties of steel: Carbon
