There are significant differences between composite concrete and ordinary concrete in multiple aspects. The following are specific point representations and summaries.
Composition Materials
Composite concrete
composed of a mixture of various materials, typically including cement, coarse aggregates, fine aggregates, admixtures, and fiber reinforced materials. The fiber reinforcement materials can be glass fiber, carbon fiber, etc., aimed at improving the strength, toughness, and durability of concrete.
Ordinary concrete: mainly composed of cement, sand, stone, and water, and may be improved by adding appropriate admixtures and admixtures to improve certain properties.
Performance Characteristics
Composite concrete
High Strength
Due to the addition of fiber reinforced materials, composite concrete has higher strength and rigidity, and can withstand larger loads.
Good Durability
With the addition of waterproofing agents, anti-corrosion agents and other additives, the composite concrete has strong corrosion resistance and durability, and can be used for a long time in harsh environments.
Strong Impermeability
It can effectively prevent water infiltration and has high waterproof performance.
Convenient Construction
It can be constructed in low temperature and humid environments, with high plasticity and good processing performance.
Ordinary Concrete
Rich in raw materials, low in cost, with good plasticity, high strength, and durability.
But compared to composite concrete, its strength and durability may be slightly inferior.
Application Field
Composite Concrete
Widely used in special engineering fields that require high strength, toughness, and durability of concrete, such as highways, bridges, tunnels, airport runways, etc.
Ordinary Concrete
It is most widely used in civil engineering, including construction, roads, water conservancy, and other fields.
Price
Composite Concrete
Due to the need to add fiber reinforcement materials, its price is slightly higher than ordinary concrete. Generally, composite fiber concrete with the same strength is about 10% -20% more expensive than ordinary concrete.
Ordinary Concrete
Relatively low cost

In summary, there are significant differences between composite concrete and ordinary concrete in terms of composition materials, performance characteristics, application fields, and prices. When choosing which type of concrete to use, it is necessary to comprehensively consider the specific engineering requirements and economic benefits.
