What is Cement?
Cement is hydraulic binder, i.e a finely ground inorganic material which, when mixed with water, forms a paste which set and hardens by means of hydration reactions and processes and which after hardening , retains its strength and stability even under water.
The United Cement Company is characterized by the production of high-quality cement products and the raw materials does not contain anything of all the impurities that have a direct impact on cement products including alkali, Chlorides, Sulphates, Potassium and Sodium in addition to the company quarry is located in part of Sarawat Mountains that are known of its high-quality raw materials. In addition, there is an automated monitors of production line which takes 100 samples a day to make sure that the products have high quality, the company assures it is high quality by sending products to local & international institutes to confirm it is high quality.
01
Ordinary Portland Cement (OPC)
Applications
mixes ordinary reinforced concrete, which do not require special types of cement) that need to withstand high strength.
Examples of use:
- Ready-mixed concrete
- Bases and foundations
- Concrete preparation in cold weather
- Bridges and build towers
- Concret Roads.
- protected
02
Sulphate Resistant Cement (SRC)
This type of cement is different from the rest of the other types, to distinguish low aluminate content tri-calcium aluminate ratio which is responsible for interaction with the Sulphate ions in the soil or water which prevents volume increasing of concrete and the occurrence of cracks in areas where the soil contains a high proportion of Sulphate.
Examples of use:
- Concrete pipe exposed to water with a high percentage of Sulphate water marshes and sewage.
- Marine works such as ports and platforms.
- Bases and foundations (that need to withstand high power.
- Sewage plants (bases of construction and foundations).
03
Portland Pozzolana Cement (PPC)
This type of cement distinct because of its specifications differ from other types of cement is made up of (70% -80%) Portland cement plus (15-20%) Pozzolana a black (volcanic) materials hundred percent natural silicon and aluminum, taken from volcanic mountains not directly exposed to any interactions or chemical additives therefore advised to use where there is any damage or disadvantages of the various uses and which gives it self great value advanced.
The characteristics and advantages:
- Plays a role in making the mixture of cement, elastic and flexible (interior and exterior finishes).
- Reduces the heat generated from the first phase of water is added
- Can prevent the alkali blocks interaction
- Reduces the permeability of cement due to its high smoothness.
- Improve the properties of plastics and cohesion (suitable for cement painting).
- Thermal insulation (saving electric power for lighting and air conditioners) consumption Noise absorption and helps in sound insulation (reduces sound
- Increases the fire resistance ability (due to the containment Pozzolananational silica and alumina, it can withstand high temperatures that occur duri
- Health- friendly material is not harmful to the environment (natural materials do not contain organic materials and has no smell and does not export t
- Resistance to salts (construction which carried out on the nearby salt water seashores or rich soil of soluble salts, which do not require bearing hig
- Resistance to weatherchanging with time passing (ancient and historical constructions consist of volcanic source rocks, especially very old Romanian p
- Health- friendly material is not harmful to the environment (natural materials do not contain organic materials and has no smell and does not export.
Examples of use:
- Factories of all kinds of Bricks Block.
- Concrete pipe exposed to water with a high percentage of Sulphate (water marshes and sewage )
- Small sewage plants.
- Small Bridges which is constructed to control the flood water in areas where the soil contains a high concentration of free Sulphate and silica.
