BUILTECH1 FINAL EXAM

A construction material that consists of a substance known as aggregate (sand and gravel), which are bonded by cement and water.

• Mortar

• Plaster

• Concrete

• Admixture

a measure of the compressive strength of concrete.

• Kilos

• Nerwtons

• Aquare Inch

• Megapascal

the separation of water from the freshly mixed concrete.

• Cracking

• Bleeding

• Crazing

• Effloresence

Good concrete should not show less than 19N/mm^2 (5%) of compressive strength when tested with the UTM after _____ days.

• 25 days

• 26 days

• 27 days

• 28 days

A concrete that is designed in such a way that it allows the water to pass through it.

• Hydraulic Concrete

• Reinforced Concrete

• Pervious Concrete

• Raw Concrete

a process that ensures a structure or object is able to keep out 100% of any water that comes into contact with it.

• Impermeability

• Watertight

• Sealant

• Waterproofing

Any non-metallic substance that is capable of holding

materials together in a functional manner by surface attachment that resists separation.

• Epoxy Resin

• Adhesive

• Mucilage

• paste

a substance used to block the passage of fluids through the surface or joints or openings in materials.

• Adhesive

• Waterproofing

• Mucilage

• Sealant

This type of coating uses a primer coat a couple of top coats applied via roller, spray, or trowel. Compared with cementitious waterproofing, this offers more flexibility. This is because it turns into a rubbery coating on your wall when the liquid cures.

• Cementitious Waterproofing

• Bituminous Coating Waterproofing

• Polyurethane Liquid Membrane Waterproofing

• Liquid Waterproofing Membrane

Well-known for their dimensional stability, high mechanical strength, chemical resistance, and affordability. Great option when bonding different metals Highly resistant to moisture, fuels, and chemicals. Good electrical insulation properties

• Epoxy Resin Adhesives

• Acrylic Adhesives

• Hot Melt Adhesives

• Anaerobic Adhesives
