CONCRETE CONSTRUCTION PRACTICES (CHAP 6)

Question 1

involves concrete
hatching, mixing, transporting, placing,
consolidating, finishing, and curing.

Answer 1

Concreting Operations

Question 2

Advantage: ______ can help in controlling the setting time and strength development of the concrete during lower temperatures.
Disadvantage: It increases the risk of slow curing, which can lead to inadequate strength gain and potential for freeze-thaw damage if not properly managed.

Answer 2

Cold-weather concreting

Question 2

Advantage: ______ can lead to
faster setting times, allowing for quicker project completion.
Disadvantage: It increases the risk of rapid
moisture loss and potential for thermal cracking, which can compromise the quality of the concrete

Answer 2

Hot-Weather Concreting

Question 3

is a construction method where concrete is poured and
set directly at the construction site into molds or forms to create structural elements like walls, columns, and slabs.

Answer 3

Cast-in-place concreting

Question 4

Floors and Roofs

______: Slabs primarily supported by beams on two opposite sides, with
bending occurring in one direction.

Answer 4

One-way slabs

Question 4

Rectangular column, circular column, foundation wall wall and footing, circular tank wall are all examples of

Answer 4

Walls and Wall Footing

Question 5

Floors and Roofs

______: Slabs directly supported by columns without beams, often with drop
panels to resist shear and moments.

Answer 5

Flat-slabs

Question 5

Floors and Roofs

______: Slabs supported on all four sides, with bending occurring in both
directions.

Answer 5

Two-way slabs

Question 6

it refer to the methods, techniques, and procedures used during the building process to ensure safe, efficient, and high-quality construction.
They include site preparation, material selection, proper use of tools and machinery, adherence to safety standards, efficient project management, and compliance with building codes and regulations.
Good ______ aim to optimize time, cost, and labor while ensuring structural integrity and sustainability.

Answer 6

Construction practices

Question 6

______ in construction management ensures that formwork is properly designed and installed to prevent accidents or failures during concrete placement and curing. -Key practices include stable foundations, proper bracing, controlled concrete placement, and systematic reshoring. -Safety also involves addressing hazards like wind during installation and removing debris to maintain a safe site

Answer 6

Framework safety
