Description
Technical field
The invention belongs to material of construction concrete field, particularly a kind of PTC pile tube concrete.
Background technology
PTC pile tube is the abbreviation of prestress thin wall concrete pipe stake, is the concrete member the most often adopted in building foundation, is widely used in the engineerings such as all kinds of building, traffic, water conservancy.China is pile tube producing country maximum in the world and uses state, and the whole nation is produced per year and all measured more than 3.5 hundred million meters in recent years.
Concrete is one of main raw material of pile tube use, is also most important raw material, concrete, referred to as " concrete (t ó ng) ": refer to the general designation being cemented to overall engineered composite material by gelling material by gathering materials.Usually concrete one word said refers to makes gelling material with cement, and sand, masonry gather materials; Coordinate by a certain percentage with water (can contain admixture and adulterant), the cement concrete obtained through stirring, also claims normal concrete, and it is widely used in civil engineering work.
But for PTC pile tube, concrete performance has important impact to it, superior with reinforcing bar adhesive property, that corrosion resistance good, acid-fast alkali-proof ability is strong, density is high concrete is the focus studied now.
Summary of the invention
