Description
Technical field
The invention belongs to pavement construction material field, more particularly, to a kind of bridge using cement and flyash as bed material
Beam expansion joint area concrete special and preparation method thereof.
Background technology
Concrete, refer to the general designation of the cementing integral engineered composite material of aggregate by binder materials.That generally says is mixed
One word of solidifying soil refers to make binder materials, sand, masonry aggregate with cement；Match somebody with somebody by a certain percentage with water (additive and admixture can be contained)
Close, it is agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in civil engineering.
Concrete has a variety of sorting techniques, is divided into inorganic coagulation material concrete by binder materials and organic cementing material is mixed
Solidifying soil；It is divided into loaded concrete, normal concrete, lightweight concrete by apparent density；It is divided into structural concrete, guarantor by using function
It is warm concrete, architectural concrete, water-proof concrete, refractory concrete, concrete for hydraulic structure, maritime concrete, road concrete, anti-
Radiate concrete etc.；By construction technology be divided into centrifugal concrete, vacuum concrete, grouted-aggregate concrete, gunite concrete, roll it is mixed
Solidifying soil, extruded concrete, pump concrete etc.；It is divided into plain (i.e. without muscle) concrete, armored concrete, steel wire by reinforcement manner
Cement, fiber concrete, prestressed concrete etc.；It is divided into dry concrete, half dry concrete, plasticity by mixture to mix
Solidifying soil, liquid concrete, high-flowing concrete, chutable concrete etc.；It is divided into flyash concrete by admixture, silicon ash is mixed
Solidifying soil, slag concrete, fiber concrete etc..In addition, concrete can be also divided into by compression strength：Low-strength concrete (pressure resistance
Degree is less than 30MPa), (compression strength is more than or equal to for middle strength concrete (compression strength 30-60Mpa) and strong concrete
60MPa)；It can be divided into again by every cubic metre of cement consumption：Lean concrete (cement consumption is no more than 170kg) and fat concrete (water
Mud dosage is not less than 230kg) etc..
To improve some properties of concrete, additive can be added.There is obvious Technological Economy to imitate due to mixing additive
Fruit, it has become the indispensable component of concrete.Concrete after workability or hardening for improvement concrete mix
Performance, cement is saved, levigate mineral material-admixture can be also mixed when concrete stirs.It is divided into active and inactive
Two classes.The property and quantity of admixture, influence intensity, deformation, the heat of hydration, impermeability and color of concrete etc..
