Concrete Basics
DANGER
Eye and skin contact with concrete materials
and breathing the dust involved is hazardous
to your health.
• Ensure that there is adequate air
ventilation.
• Wear a dust mask to prevent inhalation of
dust while using the machine; refer to
Operating Practices (page
• Avoid direct contact of cement and
concrete materials with skin and eyes.
Note:
Follow the manufacturer's instructions that are
printed on the packaging of the product that you are
using.
Concrete has the following 4 basic ingredients:
•
Sand
•
Gravel
•
Portland cement
•
Water
Depending on the application, you can use different
ratios of these 4 ingredients. The typical ratio for
mixing concrete is 1 part Portland cement, 2 parts
sand, and 3 parts gravel.
There are many variations of concrete mix recipes,
depending on the application. It is important to use
the appropriate quantity of water. Using too little water
results in dry areas in the mix, but using too much
water results in weaker concrete. The amount of water
needed varies depending on moisture content of the
sand and gravel. The mix should have a thickness
similar to peanut butter.
Keep the poured concrete damp for several days to
obtain proper curing. Evaporation results in weaker
concrete. Concrete cures through hydration, a
reaction between water and cement.
