Cement is the main material in many construction and repair works. The strength and durability of structures depends on its quality. To make the right choice, you should pay attention to several important aspects.
Main characteristics of cement
Cement grade The grade determines the compressive strength of the cement and is indicated in the format M200, M300, M400, M500, etc. For example:
M300 is suitable for plastering and screeding.
M400 is often used for pouring the foundation.
M500 is ideal for structures that must withstand high loads.
Cement composition can be:
Portland cement is universal, used for most types of construction.
Slag portland cement – suitable for construction in wet conditions.
Aluminate cement — for quick-setting structures.
Shelf life Cement loses its properties over time. Fresh cement has a loose texture, without lumps. The optimal storage period is up to 3 months from the date of production.
What to pay attention to when buying
Packaging High-quality cement is usually sold in three-layer paper bags or special plastic packages. The following must be indicated on the bag:
Name of the manufacturer.
Cement brand.
Date of manufacture.
Quality certificates Check for certificates of conformity. This ensures that the material meets the established standards.
Color and texture Quality cement has a gray or gray-green color. If there are lumps in the material, this may indicate moisture or a long shelf life.
Place of purchase Buy cement only from verified sellers or directly from manufacturers. Avoid markets where goods may be stored in improper conditions.
Tips for storing cement
Store the bags in a dry, ventilated area.
Stack them on pallets to avoid contact with moisture.
If the cement is to be used for a long time, protect it from direct sunlight and moisture.
Choosing high-quality cement is the key to successful repair or construction. Taking into account the brand, composition and storage conditions, you will ensure the strength and durability of the structures. Invest in quality materials to avoid unpleasant surprises in the future.
