Quality . Control :.
NCC quality control of its national cement products means the process of matching and setting NCC cement product's chemical, physical and mechanical properties and specifications to international specifications. This is through testing our products in NCC laboratories equipped with the latest testing and diagnosing instruments, tools and equipment used in international labs and in the cement industry. These cement quality tests are carried out around the clock; that is, throughout the different stages of the manufacturing process:
Quality tests start at . the Pre-production :.
phase of the raw materials, that is, testing the raw materials extracted from the Company's quarries.
During . Production Stages :.
Testing starts at the stage of accurate mixing ratios of raw materials, then takes place at the process of firing the raw materials in the furnace and ends with the stage of grinding .
Posts. -production Stage :.
It starts by sending the bulk cement into the silos for storage, and ends by packaging and shipment.
Quality . Assurance :.
To emphasize the importance of having its products meet and measure up to approved international quality specifications, the Company regularly sends random samples of its NCC final product to be tested and examined in international quality laboratories of European countries.
ORDINARY PORTLAND CEMENT 42.5N (OPC)
It is one of the most common types, generally used in residential and commercial buildings when sulfate salts are not present in the soil or groundwater.Ordinary Portland cement is mostly used in concrete production, where the cement is mixed with aggregates (gravel and gneiss) and water to form a homogeneous material that can be poured into reinforced concrete structures such as foundations, columns, and roofs.
Specifications :
- Portland cement CEM I 42.5N
- According to European specification EN 197–1 :2011
Product advantages :
This type is characterized by its ability to achieve high compressive strength, making it ideal for use in structures that require durability and strength.Applications and uses :
- Reinforced concrete .
- Prestressed concrete .
- Road and industrial floor concrete .
SULPHATE RESISTING PORTLAND CEMENT 42.5N (SRC)
It is a type of Portland cement with unique properties that make it suitable for use in certain environments exposed to high concentrations of sulfate salts.Specifications :
- Sulfate-Resistant Portland Cement CEM I – SR3 – 42.5N
- According to European specification EN 197 - 1: 2011
Product advantages :
This type of cement differs from other types in that it has a low content of tricalcium aluminate, which is responsible for reacting with sulfate ions present in soil or water, thus preventing expansion, cracking, and fissures in concrete in areas where the soil contains a high percentage of sulfate salts.Applications and uses :
- Plain and reinforced concrete works exposed to sulfate salts in soil and groundwater.
- Concrete works in sewage and water pipelines and treatment plants.
- Concrete works for piles and their types.
- Concrete foundation works in coastal areas, and concrete barriers used to protect beaches.
- Used in the construction of marine structures such as docks and ports.
PORTLAND POZZOLANA CEMENT 42.5N (PPC)
This cement is one of the most important products for all cement companies worldwide. It is manufactured by adding a specific percentage of natural pozzolana to improve the cement's properties. This natural substance contains silica, which reacts with the cement components during the hydration process, forming additional compounds that enhance the concrete's durability and reduce its permeability.Specifications :
- Portland Pozzolana CEM II \ A-P 42.5N
- According to European specification EN 197-1:2011
Product advantages :
- Increased strength and durability of concrete due to the presence of active silicates in pozzolana, which improves cement properties and extends the lifespan of buildings.
- Low heat of hydration of cement, which qualifies pozzolanic Portland cement for use in concrete pours for thick and large foundations, such as slabs, resulting in no cracks appearing on the concrete surface.
- Reduces the possibility of new concrete being exposed to rust.
Applications and uses :
- Reinforced concrete structures for large construction projects.
- For massive foundations and thick footings such as concrete slabs.
- Concrete dams, barriers, and canals for floodwater and irrigation projects.
PORTLAND CEMENT for finishing 22.5X (MC)
It is a type of construction cement and a special product to cover the needs of the Yemeni market for finishing works. It is characterised by its high smoothness and high workability.Specifications :
- construction cement MC-22.5X
- According to European specification BS EN 413-1:2011
Product advantages :
- This cement provides a smooth, even, and uniform surface.
- Easy to apply and wipe, and fills gaps for all cementitious finishing works.
- Reduces painting costs due to its light color.
- Reduces cracking due to low cement hydration temperature.
- Lower cost for cement finishing work.
Applications and uses :
- All types of cladding works.
- Construction works (blocks and stones).
- Sidewalk floors.
- All types of tile installation works.
Portland composite cement : 32.5R 1.5 ton package (PCC)
It is a type of Portland cement. It is manufactured by adding specific proportions of limestone and natural pozzolana to the clinker. It is characterized by a high degree of softness, resulting in rapid hardening. It is used in automatic block factories.Specifications :
- Portland composite cement CEM II\B-M 32.5 R
- According to European specification 2011 EN
Product advantages :
- This cement is characterized by its medium-temperature hydration, which reduces cracks in ready-mix concrete.
- High workability, providing ready-mix concrete with high flexibility and plasticity.
- Lower water consumption during the spraying process for reinforced concrete.
- It reduces porosity and permeability and minimizes moisture and water infiltration in concrete due to its high smoothness.
Applications and uses :
- Automatic Block Factories
- Reinforced concrete works for residential buildings that do not require high compressive strength.
- Normal concrete works for floors.
ORDINARY PORTLAND CEMENT 52.5N (OPC)
It is a type of Portland cement characterized by a high compressive strength of 52.5 N.It provides the necessary resistance in a short period of time, as the endurance provided by this type in two days and a week is equal to that provided by ordinary Portland cement in one week and 28 days, allowing the removal of forms and supports in a shorter time.
Specifications :
- Portland cement CEM I \ 52.5 N
- According to European specification EN 197-1:2011
Product advantages :
Portland cement 52.5N reduces the waiting period between different construction phases, which contributes to accelerating the project schedule for projects that require rapid delivery, such as road or bridge construction, as well as repair and rehabilitation works, where speed of construction and early completion are required due to time and space constraints.Applications and uses :
- Towers and tall buildings.
- Roads, bridges, and tunnels.
- Huge construction projects.
