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 Safe Operating Practices.
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.
