KU ARCH626 BTECH I concrete 1

cement clinker

a hardened material produced by heating limestone and clay to high temperatures

sustainable issues

lots of carbon (8%) (fly ash is an alternative to lesson)

Life cycle assesment

investigation into environmental impact, input of materials and output of waist

ASTM

industry standards

slump test

measures concrete's consistency (workability) using a cone on a level surface, filling cone then lifting the cone and measuring the slump to determine if the concrete is too wet or dry for the project's needs

Retarding mixtures

slow down curing times

Air entrancing additives

increases air in concrete, along with durability (when water expands and freezes)

Steel X

structural walls inside of building, small/twisted

secondary reinforcement

nylon and fiber mixes

how deep does light framed construction go?

Beneath frost line

how deep does heavy framed construction go?

lower for foundation; to bedrock

Hydrostatic pressure

water putting weight on building

mudjacking

pump mud underneath to fill settlement

Spalled concrete

loss of structural integrity, curing process interupted, or overworked

Radiant heat

heating surface so heat spreads into nearby air, allows for different temps throughout rooms

hardeners and densifiers

Pore filler increases surface density, before its grinded and polished

Shake on colors

freshly placed concrete, uv stable colors

Integral coloring

coloring added when making mix, uv resistant, exposed to sun

Acid stains

color applied after curing, molted color, only as durable as the surface its put on. (extra maintenance)

Water based dyes

oderless, nontoxic, not uv resistant, easy to apply, and added before floor hardens

Epoxy seelers

longlisting, abrasion resistant, high gloss/matt

One way floor/slab

predominantly carries and transfers loads in one direction, perpendicular to its supports

2 way system

transfers loads in both horizontal directions to supporting elements like columns or beams

Cast-in-Place Concrete

Concrete that is poured in its final location, 2 way

Post-Tension Concrete

a structural system where high-strength steel tendons are placed within the concrete and are pulled.

ICF

Insulated concrete form (high density polystyrene
