 Key Answers, Explanations, Notes, and Concepts

81) Which refers to the ease with which the fresh concrete can be molded without segregation? a. Plasticity b. Consistency c. Mobility d. Grout
Answer: a. Plasticity

Plasticity-
Consistency- its property of mobility or fluidity. Consistency means the property of holding together all the ingredients without leading to segregation of mortar. It generally ranges from stiff to fluid.

Mobility- is the property of flowing of fresh mortar under the influence of gravitation and by the external force.
Grout- is a cementitious mixture used to fill cores or cavities in masonry construction. While usually added for structural reasons, grout can also increase: fire ratings, security, acoustical performance, termite resistance, blast resistance, thermal storage capacity and anchorage capabilities.
82) Which refers to the degree of wetness or slump of the concrete mixture? a. Plasticity b. Consistency c. Mobility d. Grout
Answer: b. Consistency
83) Which is an artificial stone that results from mixing cement, sand, gravel, and water? a. Concrete b. Grout c. Mortar d. Bricks
Answer: a. Concrete

Concrete - is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time.
Grout - is a cementitious mixture used to fill cores or cavities in masonry construction. While usually added for structural reasons, grout can also increase: fire ratings, security, acoustical performance, termite resistance, blast resistance, thermal storage capacity and anchorage capabilities.
Mortar - is a material used in masonry construction to fill the gaps between the bricks and blocks. Mortar is a mixture of sand, a binder such as cement or lime, and water and is applied as a paste which then sets hard.

Bricks - is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term brick denotes a block composed of dried clay, but is now also used informally to denote other chemically cured construction blocks.

84) Which is an artificial stone that results from mixing cement, sand, and water? a. Concrete b. Grout c. Mortar d. Bricks
Answer: c. Mortar

85) Which is an artificial stone that results from mixing cement and water? a. Concrete b. Grout c. Mortar d. Bricks
Answer: b. Grout
86) Which term refers to the process of finishing using mortar? a. Finishing b. Fine finishing c. Concreting d. Plastering

Answer: d. Plastering

Plastering - is a thin layer of mortar applied over the masonry surface and it acts as a damp-proof coat over the brick masonry work. Plastering also provides a finished surface over the masonry that is firm and smooth hence it enhances the appearance of the building.
