1Per TESDA Masonry NC II (CON712301), what is the primary purpose of preparing masonry materials before laying or plastering?
A.To ensure correct mix proportions, quantity, and timely supply to masons on site
B.To eliminate the need for curing after block laying
C.To replace structural reinforcement in hollow block walls
D.To waterproof finished masonry surfaces permanently
Explanation: CON712301 requires selecting, hauling, and mixing mortar or concrete according to work instructions so the correct quantity and mix reach the appropriate personnel. This underpins quality laying and plastering but does not replace reinforcement, curing, or waterproofing steps.
2A trainee is hauling cement bags and sand to a mixing area. Which PPE items are specified in the Masonry NC II range of variables for this task?
A.Helmet, safety shoes, gloves, dust mask, and safety glasses as required
B.Rubber apron only without other PPE
C.Hearing protection only because hauling is noisy
D.Welding helmet and face shield
Explanation: The TR range of variables lists helmet, safety shoes, proper uniform, gloves, dust mask, and safety glasses as PPE for masonry work. Cement and sand handling exposes workers to dust and impact hazards, so respiratory and eye protection are included.
3What materials may be included when preparing masonry mixes under Masonry NC II, per the range of variables?
A.Cement, sand, water, lime, fly ash, CHB, bricks, and reinforcing bars
B.Only paint and thinners for finishing
C.Structural steel beams and precast slabs only
D.Asphalt and bitumen waterproofing compounds only
Explanation: The TR explicitly lists concrete hollow blocks, bricks, cement, sand, water, reinforcing bars/GI wire, nails, lumber, balusters, lime, and fly ash among masonry-related materials.
4Before mixing mortar, a mason checks tools and equipment. Which action aligns with CON712301 performance criteria?
A.Verify mixing tools and equipment are serviceable and suited to the required batch size
B.Begin mixing immediately without inspecting the mixer
C.Use any available tools regardless of job requirements
D.Discard water to make a stiffer mix without instruction
Explanation: Element 3.1 requires checking mixing tools and equipment according to job requirements before determining mix and quantity. Serviceable, appropriate equipment ensures uniform mixes and safe operation.
5A foreman instructs a 1:3 cement-to-sand mortar mix by volume for CHB laying. How should the mason interpret this proportion?
A.One part cement to three parts sand measured by loose volume, typically with water added to workable consistency
B.Three parts cement to one part sand for maximum strength only
C.One bag of cement to three liters of water without sand
D.Equal volumes of cement and sand regardless of the instruction
Explanation: Volume proportions such as 1:3 describe the ratio of binder to fine aggregate. Water is added separately to achieve workability suitable for bedding and jointing hollow blocks without excess bleed.
6Why is clean potable water preferred when mixing masonry mortar on a TESDA training site?
A.Impurities can interfere with cement hydration, strength development, and bond to units
B.Dirty water makes mortar set faster for quicker laying
C.Salt water improves adhesion to concrete hollow blocks
D.Water quality has no effect if enough cement is used
Explanation: Cement hydration requires reasonably clean water. Salts, oils, or excessive silt can retard or weaken set, reduce bond, and cause efflorescence or discoloration on finished work.
7After mixing a batch of mortar, what must the mason do per CON712301 Element 3.4?
A.Supply the mixed mortar to the appropriate personnel based on job requirements
B.Store unused mortar indefinitely without covering
C.Add extra water every hour to keep it usable for days
D.Discard all mortar if not used within five minutes regardless of condition
Explanation: Mixed mortar must be delivered promptly to the workers who need it, maintaining workflow and preventing excessive stiffening or segregation before use.
8Which tool is most appropriate for spreading mortar on the bed joint of a concrete hollow block wall?
A.Mason's trowel
B.Wire brush only
C.Paint roller
D.Spirit level used as a spreader
Explanation: A mason's trowel is designed to pick up, spread, and strike mortar on bed and head joints with control over thickness and coverage.
9What is the function of sand in a masonry mortar mix?
A.Provides bulk, workability, and reduces shrinkage while filling voids between cement particles
B.Replaces cement entirely in structural mortar
C.Prevents all need for curing after laying
D.Acts only as a coloring agent for joints
Explanation: Sand is the fine aggregate that makes mortar economical and workable. It reduces cement paste volume, controls shrinkage, and helps achieve uniform joint thickness.
10A mason stockpiles sand near the mixing area. What is a good practice aligned with material preparation competencies?
A.Keep sand on a clean, hard platform and protect it from organic matter and contaminants
B.Mix sand with topsoil to improve texture
C.Pile sand directly in mud to retain moisture
D.Allow diesel spills on sand to ease mixing
Explanation: Clean, controlled stockpiling prevents clay, debris, and chemicals from altering mix proportions and mortar strength. Platforms also reduce moisture variation from ground contact.
