How to Check the Quality of Cement in Nigeria
The construction sector is booming in Nigeria and the need for more construction materials like cement, sand and reinforcement is exponentially increasing. As this materials demand is increasing, the quality is always tampered with. This article will show you simple ways to check the quality of cement. 1. Date of Packaging: Unlike wine, the strength of cement being used decreases with time. Cement should be used before 90 days from the date of manufacture. A year after manufacture, the strength of the cement is reduced by 40–50%. 2) Cement colour: Good cement is always uniform in colour. You can identify good cement by its gray colour with a slightly green shade. 3) moisture in cement: In cement, lumps are formed due to the absorption of moisture. Good cement has no lumps. 4) Temperature: If you push your hand inside a bag of good cement, you should feel a certain coolness. Bad cement feels warm in your hand. 5) Good quality cement floats in water for some time before sinking.
