1ARCC- BT BASIC CONSTRUCTION CONCEPTS, PRINCIPLES, TERMINOLOGIES

Construction

The art, science and business of building; the process of building from site preparation through erection, assembly and finishing; the manner in which materials are ordered assembled, and united into a whole, as frame construction; all on site work done from site preparation, excavation, foundation assembly of all components and installation of utilities and equipment of building or structure.

Erection

Installation in place of components of a building or structure.

Renovation

Any physical change made on a building or structure to increase its value, utility, and or improve its aesthetic quality

Alteration

Construction in a building or structure involving changes in the material used, partitioning, location and size of openings, structural parts, existing utilities and equipment but does not increase the overall area thereof,

Addition

Any construction which increases height or area of an existing building or structure

Conversion

Change in the use or occupancy of a building or structure or any portion thereof which has different requirements.

Repair

Remedial work done on any damaged or deteriorated portion of a building to restore its original condition

Moving

The transfer of any building or structure or portion thereof from its original location or position to another either with the same lot or a different one

Demolition

The systematic dismantling or destruction of a building or structure, in whole or in par

Type 1

A type of construction based on the NBC for wood construction

Type 2

A type of construction based on the NBC for wood construction with 1hr fire resistivity

Type 3

A type of construction based on the NBC for masonry and wood consgtruction, exterior walls are fire resistive

Type 4

A type of construction based on the NBC for steel, iron, concrete or masonry where walls, ceilings and permanent partition are fire resistive

Type 5

A type of construction based on the NBC for steel iron, conccrete, or masonry where all are fire resistive

Enumerate what the construction documents consists of

d. all of these (they are all terms pertaining to reinforced concrete)

"A term which specifically refers to concrete in which steel is embedded in such a manner that the two materials act together in resisting forces.

a. ferroconcrete

b. beton arne'

c. reinforced concrete

d. all of these

structural concrete

A general term which refers to concrete used for structural purposed such as in columns, beams, slabs, footings, etc.

on site directly into fromworks

cast in situ concrete is done _____________

aggregate, water, cement

enumerate tthe components of plain concrete

no they are used to create reinforced concrete

are rebars a component of plain concrete?

Hydraulic concrete

concrete that sets and hardens rapidly when mixed with water, allowing it to cure even underwater, making it ideal for wet environments like underwater structures and for patching leaks.

Hydraulic cement, water, aggregates

components of a hydraulic concrete

control joint

a kind of joint that created lines of weakness so that cracking that may result from tensile stress occurs along pre determined lines thereby containing cracks on a particular area (Tells the concrete "if you crack, crack here.")

construction joint

Joint used when vertical and horizontal surface is reinforced concrete where concreting was stopped and continued later

40kgs/ 88lbs

standard commercial weight per bag of cement

smaller than 1/4" (6.4mm), 3/8" (9.5mm)

fine aggregate are aggregates with particle size ___________ and passes through a ___________ sieve

larger than 1/4" (6.4 mm), 3/8" (9.5 mm)

course aggregates are Aggregate with particle size _____________ and retained on a ________________ sieve.

deformed bars

what kind of bar is commonly specified and used in reinforcing structural concrete members such as columns, beams, footings, slabs, etc.?

lugs

what do you call the surface deformations on adeformed bar which provides grip between concrete and steel reinforcement?

80%

theoretically, how many percent of its ultimate strength does concrete aquire in 3 months or 84 days?

cement-aggregate ratio, water cement ratio, curing condition of concrete

what are the factors or parameters affecting the compressive strength of concrete?

exposure to elements and fire, age of concrete, methods of mixing and placement of concrete

what are the factors affecting the compressive strength of concrete?

construction joint

joint where two successive placements of concrete meet is known as

temperature reinforcement

in a slab, there are reinforcements placed perpendicular to the principal reinforcement in a oneway slab to absorb stresses resulting from shrinkage or changes in temperature. What is it?

75mm

what is the allowable slump value in mm of beams and columns

slump test

A test for mixed concrete to determine consistency, plasticity and workability.

compressive, tensile

concrete is high in ___________ strength while steel is high in ____________ strength

bonding

a term denoting adhesion between two substances or surfaces such as concrete and steel or old and new concrete

concrete cover

amount or thickness of concrete used to protect steel reinforcement from fire and oxidation,

measured from the outer surface of concrete to the surface of steel.

how is concrete cover measured

admixture

which component of concrete may be used to alter properties of concrete matrix

web bars

in a beam seactio, what do you call that reinforcement that is placed between the top and bottom fibers

a. 45 deg

as far as code requirement is concerner which of the following hook angles is not a stanndard hook angle?

a. 45deg

b. 90deg

c. 135deg

d. 180deg

domes

in a waffle slab system, what do you call those forms that are placed side by side and provides coffering on the underside upon removal of such forms

provide end hook on bars

what simplest alternative or substitute my be done on a concrete mass to strengthen it and increase load capacity even if space is limited to provided proper change

10mm

what is the minimum size of spiral tie that should be used in a spiral column
