Frequently Asked Questions.
|Cement:||The binding element in both concrete and mortar.|
|Concrete:||A product composed of cement, sand and gravel or other coarse aggregate. When water is mixed in with this product, it activates the cement, which is the element responsible for binding the mix together to form one solid object.|
|Mortar:||A product composed of cement and sand. When water is mixed in with this product, the cement is activated. Whereas concrete can stand alone, mortar is used to hold together bricks, stones or other such components.|
|Cement Mixing:||Cement mixing, therefore, properly speaking, refers to using cement in the mixing of mortar or concrete.|
Cement comprises 7-15% of total concrete volume. As an alkaline material, wet cement is caustic and can cause severe chemical burns to exposed skin and eyes. Thus, working with fresh concrete presents an obvious risk. That’s why it’s so important to always wear water-proof gloves, a long-sleeved shirt, full-length trousers and proper eye protection. If you have to stand in wet concrete, use water-proof boots that are high enough to keep concrete from flowing into them. Wash wet concrete, mortar, cement, or cement mixtures from your skin immediately. Flush eyes with clean water immediately after contact. Indirect contact through clothing can be as serious as direct contact, so promptly rinse out wet concrete, mortar, cement or cement mixtures from clothing. Always seek immediate medical attention if you have persistent or severe discomfort.
In addition to the caustic nature of cement, 95% of cement particles are smaller than 45 µm.–compared to tobacco smoke of approximately 3 µm–suggesting that the danger of inhalation is possible. Workers opening bags or sacks of cement and cement products should always wear a dust mask in addition to their regular safety attire.
