Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of high performance concrete and preparation method thereof.
Background technique
Concrete is a kind of cement-base composite material, it be using cement as cementing agent, in conjunction with it is various gather materials, additive etc. and
The hydraulic cementing materials of formation.However, due to normal concrete brittleness is big, intensity (especially tensile strength) is low, anti-chlorine from
Son corrodes and the reasons such as durability difference, seriously affects and limit its use scope.Meanwhile for low intensive concrete,
When meeting identical function, cement consumption is larger, this exacerbates the consumption to natural resources and the energy, in addition also increases exhaust gas
With the discharge of dust, the pollution of the demand and environment to the energy is increased.
High performance concrete, abbreviation HPC (High Performance Concrete), be over the past thirty years in most create
The cement base engineering material of new property, HPC has excellent mechanical property, and including high compression strength, excellent shock resistance resists
The advantages that fatigue behaviour, tensile property, high toughness；In addition, HPC material internal is fine and close, there is splendid durability.Therefore, it grinds
Study carefully prepare high performance concrete can improve to building long-term behaviour and life-cycle cost reduce overall economic efficiency and to ring
The social benefit of the social sustainable developments such as guarantor, energy conservation, low-carbon.
Summary of the invention
The purpose of the present invention is to provide a kind of high performance concretes and preparation method thereof, and preparation method is simple, and have
Have the advantages that high compression strength, excellent shock resistance, anti-fatigue performance, tensile property, toughness are high.
The present invention provides a kind of high performance concrete, which includes the component of following mass parts: cement 200-400
