Concrete

material manufactured from thin layers (plies) of wood veneer that are glued together

Plywood

Integral concrete characteristic

Color lasts longer

Location of pump to pool

As near as possible

Measure of luminous flux (quantity of light energy emitted per second in all directions)

Lumens

Unit of light INTENSITY

Candela (Candlepower CP)

Measure of Luminance

Footcandle (1 sq ft) / Lux (1 sqm)

Types of fusion welding

Gas Flame Electric-arc

- Weakest method of joining metals - Uses solders (alloys of tin and lead)

Soldering

Type of soldering that uses higher temperatures and stronger + higher melting alloys

Brazing

- Alloy of copper (Cu) and tin (Sn) - Rizal Monument and other statues

Bronze

- Alloy of copper (Cu) and zinc (Zn) - Reacts with other metals

Brass

Used as a protective coating (galvanizing)

Zinc

Impure form of iron; commercial form in which iron is first prepared

Crude / Pig Iron

Galvanizing method - chemical treatment with electrochemical reaction - allows steel to bond with zinc

Hot-dip Galvanizing

Gneiss Marble Quartzite Slate

Metamorphic

Shale Coal Limestone Sandstone

Sedimentary

Granite Quartz Obsidian Pumice Obsidian

Igneous

Water content of the soil when the remainder of water has been removed by gravity

Field Capacity

The minimum amount of water in the soil that the plant requires not to wilt; exceeding will kill the plant

Permanent wilting point

Refers to the amount of clay particles in a soil sample

Colloidal Content

Moisture content at which a soil changes from a liquid to a plastic state

Liquid Limit (LL)

Moisture content at which a fine-grained soil can no longer be remolded without cracking (crumble)

Plastic Limit (PL)

Water content at which further loss of moisture will not cause a decrease in volume

Shrinkage Limit

The study of the origin and formation of soil (from bedrock to horizons)

Pedogenesis

Combination of geosynthetic components; has a - core (void space for water) - geotextile filter (prevents soil from entering voids)

Geocomposites

3D prefabricated polymeric system; voids are filled for stabilization

Geocells

Impermeable polymeric sheets used for pond lining and waterproofing

Geomembranes

Woven or nonwoven fabric used for reinforcement, separation, filtration, and in-plane drainage (permeable to water and gases)

Geotextiles

- Main horizonal support (beam) that supports smaller beams - Carries the floor joist and flooring

Girder (Suleras)

- Recently formed soils that lack well-developed horizons - Recently deposited sediments that will develop into another soil type

Entisol

Heavy clay soils that expand and contract due to moisture

Vertisol

Added to slow setting time of concrete

Gypsum

Added to improve concrete plasticity and workability; faster curing time

Lime
