Description
Technical field
The invention belongs to technical field of concrete, and in particular to a kind of construction high-weatherability concrete and its preparation
Method.
Background technology
Concrete, referred to as " concrete (t ó ng) "：Refer to the cementing integral engineered composite material of aggregate by cementitious material
General designation.One word of concrete usually said refers to make cementitious material, sand, masonry aggregate with cement；With water (additive can be contained and mixed
Close material) coordinate by a certain percentage, it is agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in building work
Journey.
Concrete there are many sorting technique, it is most common have it is following several：
It is divided by cementitious material：
1. inorganic coagulation material concrete, inorganic coagulation material concrete includes the siliceous cementitious material concrete of lime (such as
Silicate concrete), portland cement series concrete (such as portland cement, ordinary cement, slag cements, pulverized fuel ash cement, fire
Mountain grey matter cement, cement etc.).Calcium aluminium cement series concrete (such as high alumina cement, fine aluminium acid salt cement, injection water
Mud, ultra-quick cement concrete etc.), plaster concrete, magnesium cement concrete, sulphur concrete, waterglass prodan mix
Solidifying soil, betonanc (cement being replaced to make cementing material with metal) etc..
2. organic cementitious material concrete.Organic cementitious material concrete mainly has bituminous concrete and polymer cement to mix
Solidifying soil, resin concrete, polymer impregnated concrete etc..It, can be in addition, inorganic with organic composite colloidal materials concrete
Divide polymer cement concrete and polymer volume indigo concrete.
It is divided by apparent density：
Loaded concrete, normal concrete, lightweight concrete.These three concrete differences are exactly the difference of aggregate.Weight
Concrete is that apparent density is more than 2500 kilograms/cubic metre, use it is especially closely knit and especially heavy gather materials it is manufactured.As barite mixes
Solidifying soil, steel cuttings concrete etc., they have impermeable x-ray and gamma-ray performance；Often it is formulated by barite and iron ore.
Normal concrete is our common concrete under construction, and apparent density is 1950~2500Kg/ cubic metres, mainly with
Sand, stone are formulated mainly to gather materials, and are most common concrete species in civil engineering.Lightweight concrete is apparent density
Less than the concrete of 1950 kilograms/cubic metre.
For concrete, the current country is primarily present following patent document：
