a measure of the compressive strength of concrete.

the separation of water from the freshly mixed concrete.

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

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

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

Any non-metallic substance that is capable of holding

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

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

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.

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

A paint finish that is Smooth, has little or no sheen. Helps hide surface imperfections but may suffer damage more easily than other finishes. Best for low-traffic areas.

A paint made from dissolved asphalt or tar (gives black color). Waterproof and alkali resistant. Not suitable to surfaces exposed to sunlight (deteriorate).

A paint that Uses white lead as base. Applies in three coats: primer, undercoat and finish coat. Mat and glossy while durable and affordable. Easy to clean. Commonly applied in walls, doors and windows.

Paints are a major source of indoor air pollution. The US Environmental Protection Agency puts paint on its top-five list of environmental hazards. Conventional paints can make indoor air a chemical cocktail, even long after they have dried, as they continue to release petroleum based solvents, called Volatile Organic Compounds (VOCs) as they cure.

-Made from linseed oil, zinc chrome and fine sand

- Chemical resistant

- Durable and affordable

- Commonly used on metallic surfaces such as pipes

- this Paints are not ready to use.

a group of materials, either synthetic or naturally occurring elements that may be molded when soft and hardened to retain given shape.

Anything that are manmade which do not occur in nature. They are artificially and chemically produced be it in a laboratory or industrial site.

Soft and flexible (Example Polyethylene). Not elastic like rubber and steel springs moulded to any desired shape or stretched or spread as sheets.

A transparent thermoplastic used as a lightweight, shatter-

resistant alternative to glass.

A plastic material, which exists in various forms. It

can be tailored to be either rigid or flexible, and is the

material of choice for a broad range of end-user

applications such as: insulation of refrigerators and

freezers. building insulation. cushioning for furniture.

This are materials that can be found and collected locally

within a certain region, country, or area.

a building material has high compressive

strength and low weight has been one of the most

used building material as support for concrete,

especially in those locations where it is found in

abundance.

A Material used in concrete construction as an alternative of cement.

A hardwood-substitute. It is a new timber resource that comes from plantation crops and offers an alternative to

rainforest timber.

an ancient building material that has been used

in a variety of countries and building types. It is used as a construction material. It is a fast-growing, locally available resource, which is inexpensive, lightweight, allows natural ventilation, flexibility and has excellent construction qualities.
