General Use Portland Cement Marco GU is a high quality hydraulic binder composed of premium raw materials. Marco Cement undergoes rigorous laboratory testing and quality control. Designed for use in most concrete work, it meets the required compressive strength in accordance with CSA A3001-03 (Test Method A3004-C2). Portland Cement GU complies with CSA-A3000.
Portland Cement GU is used in the formulation of high strength concrete and mortars and for any other application requiring a general purpose cement.
The yield depends on the end use of the cement. For concrete, 120 Kg of Portland Cement GU give a coverage of 0.4
Use drinking water. Use loose or bagged concrete aggregates, either natural or crushed stone, and clean, no-residue sand. To prevent the concrete surface from drying out, it is important to protect it for the first 24 to 48 hours. Cover it with a damp burlap or plastic wrap. Use the minimum amount of water required to achieve the desired consistency. Excess water weakens the mechanical properties of the product. Protect from freezing for at least 24-48 hours.
GU Portland General Purpose Cement is available in 30 kg and 40 kg bags.
Store in a dry place protected from the weather. Unopened bags have a shelf life of 12 months.
Precautions : Cement and water produce a caustic solution. In case of contact with the skin, wash thoroughly without delay. In case of contact with eyes, rinse immediately with plenty of water. Be careful and wear protective clothing: gloves, safety glasses, safety shoes, mask. If discomfort persists, consult a doctor. See Material Safety Data Sheet (MSDS) for first aid.
Recommended all-purpose mixture :
1 part Cement
2 parts of Crushed Stones
3 parts of Sand
Mechanical mixing for concrete : Start the mixer. Pour 3/4 of the required amount of water, the stone, then the sand. When the mixture is homogeneous, add the cement gradually. Gradually add the remaining water until the recommended consistency. Continue kneading for a further 3 minutes to obtain a homogeneous mixture.
Mechanical mixing for mortar : When the mixer is stopped, initially introduce half of the water intended for mixing. Start the mixer and introduce 50% of the required volume of sand. Introduce the cement and the remaining volume of sand by kneading. Gradually add the remaining water until the recommended consistency. Continue kneading for a minimum of 5 minutes to a maximum of 10 minutes until the desired uniform consistency is obtained.
Manual Mixing : Mix well, on a clean, hard surface or in a wheelbarrow, dry materials. Gradually add the required water while mixing with the shovel to obtain the recommended consistency. It is best to mix the mortar mechanically.
