Mannok General Purpose Cement – 25kg Weatherproof Bag

About this item:
Mannok General Purpose Cement is a CEM II/A-L 32.5R Portland-limestone cement suitable for a broad range of concrete, mortar, plaster, render and screed applications. Its balanced strength development and consistent composition make it a practical everyday cement for brickwork, blockwork, small foundations, floor screeds and general building repairs. Contractors and experienced DIY users would choose it where one dependable bagged cement is required across several standard construction tasks.

The 32.5R strength class provides reliable early strength development when the cement is correctly proportioned, mixed, placed and cured. Supplied in a 25kg weatherproof plastic bag, it is easier to handle on site and better protected against short-term exposure to moisture than conventional paper packaging. Weatherproof packaging does not replace dry storage: bags should remain sealed, covered and raised clear of damp ground. For structural work, the complete concrete or mortar specification (not the cement alone) must meet the required strength and exposure conditions.

Common Questions:
Q. What is the difference between General Purpose Cement and Mannok Master Grade Cement?
A. General Purpose Cement is a versatile option for concrete, mortar, plaster, render and screed. Master Grade Cement contains an air-entraining agent and is formulated specifically to improve the workability and finishing of mortar and plaster mixes.

Q. Can Mannok General Purpose Cement be used for structural concrete?
A. Yes, provided the complete concrete mix is designed to meet the specified strength and exposure class. Follow the project specification and seek engineering guidance where structural performance is required.

Q. What mixing ratio should be used?
A. The correct ratio depends on whether the cement is being used for concrete, mortar, render or screed. Follow the specified mix design and measure the cement, aggregates and clean water accurately rather than relying on an approximate universal ratio.

Q. Can the weatherproof bag be stored outside?
A. The plastic packaging provides improved resistance to moisture but is not intended for prolonged uncovered outdoor storage. Keep the bag sealed, off the ground and protected from rain, standing water and damage.

Q. Can cement still be used if the bag contains lumps?
A. Small soft lumps may break down during mixing, but hard lumps indicate that moisture has entered and hydration has begun. Cement containing hard material should not be used where dependable strength is required.
