Blockwork is masonry which uses large blocks made out of concrete, rather than bricks.
To dustproof concrete blockwork, you will need to apply a sealer. Polyurethane is a popular sealer for this purpose.

The amount of sand in a 1m² area of blockwork depends on the thickness of the mortar joint and the size of the blocks. Typically, for standard blockwork, about 0.1 to 0.15 cubic meters of sand may be required for the mortar. This can vary based on the specific design and construction practices used. Always consult construction guidelines or a professional for precise calculations.

The amount of mortar required for 1 m² of blockwork typically ranges from 0.1 to 0.2 cubic meters, depending on the size of the blocks, the joint thickness, and the laying technique. Generally, for standard block sizes and a joint thickness of about 10 mm, you can estimate around 0.1 cubic meters of mortar per m². It's important to adjust this estimate based on specific project conditions and block dimensions.
To calculate the consumption of mortar in blockwork, first determine the total area of the blocks being laid. Then, estimate the joint thickness (typically between 10-15 mm) and calculate the volume of mortar needed for the joints by multiplying the total area by the joint thickness. Finally, convert this volume to bags of mortar based on the volume covered by one bag, usually provided by the manufacturer. Adjust for wastage, typically around 10%.
To effectively paint concrete blockwork for enhanced appearance and durability, follow these steps: Clean the surface thoroughly to remove dirt, grease, and loose particles. Apply a primer specifically designed for concrete surfaces to improve adhesion. Use a high-quality masonry paint that is breathable and water-resistant for durability. Apply the paint in thin, even coats using a roller or brush for a smooth finish. Allow each coat to dry completely before applying the next layer. Consider adding a sealant or topcoat for extra protection against moisture and UV damage.
To calculate the square meters of a roof, you only need the length and width of the roof area, not the height. For a roof measuring 5 meters by 5.5 meters, multiply the length by the width: 5m x 5.5m = 27.5 square meters. The height of the roof does not factor into this calculation.
