Abstract
The invention provides a quick-hardening early-strength concrete, and a preparation method thereof. The quick-hardening early-strength concrete is composed of sulphate aluminium cement, an aggregate, a water reducing agent, an early strength agent, a retarder, an antifoaming agent, and a levelling agent. The quick-hardening early-strength concrete is a high performance concrete prepared via super high-early-strength concrete and high-strength concrete technology, and possesses following characteristics: setting time is short, early strength is high, reduce of later strength is not caused, durability is excellent, and the quick-hardening early-strength concrete can be used for completing roadway mending and getting the traffic moving again in a short time.
Description
Technical field
The present invention relates to concrete field, more particularly to a kind of high-early strength concrete and preparation method thereof.
Background technology
Compared with portland cement concrete, performance is greatly improved and improves high-early strength concrete.By to general
The adjustment of logical proportioning of cement concrete, and add additive and other materials, reaches higher intensity and preferably
Performance, to meet construction technology and use requirement.Due to larger load will be born, therefore it is required that must have enough strong
Degree.In addition, in the case that road needs urgent repairing, need to complete to construct within the time the shortest and resume traffic.
, due to low intensity, hardening time is long for portland cement concrete, is not suitable for the place much repaired, and for this, we need
To use a kind of special concrete, this concrete need to possess characteristic：
1. the engineering time is short；
2. in the short time, obtain higher intensity；
3. it is fully cured rear intensity high.
Content of the invention
For the above-mentioned technical requirements to repairing special concrete, the present invention provide a kind of high-early strength concrete and its
Preparation method, to meet the applications such as bridge, harbour and military project repairing.
For achieving the above object, the present invention adopts the following technical scheme that:
The present invention provides a kind of high-early strength concrete it is characterised in that by sulphate aluminium cement, gathering materials, water reducer, early strength agent,
Retarder, defoamer, levelling agent forms.
Described fast hardening concrete is made up of following raw materials according in parts by weight：100 parts of sulphate aluminium cement, 90～
110 parts gather materials, 3～7 parts of water reducer, 0.05～0.4 part of early strength agent, 0.05～0.4 part of retarder, 0.1～0.4 part
Defoamer, 0.1～0.4 part of levelling agent, 20～40 parts of water.
Described gather materials for 80-120 mesh quartz sand, flyash and Calx one or more.
Described early strength agent is lithium carbonate and calcium formate.
Described retarder is boric acid and tartaric acid.
The preparation method of described high-early strength concrete it is characterised in that：
（1）Mixing and stirring of gathering materials by the sulphate aluminium cement of 100 parts of weight portion meter and 90～110 parts；
（2）To above-mentioned steps（1）0.1～0.4 part of defoamer of middle interpolation and 0.1～0.4 part of levelling agent mixing and stirring；
（3）To above-mentioned steps（2）3～7 parts of water reducers of middle interpolation and 0.05～0.4 part of early strength agent mixing and stirring；
（4）To above-mentioned steps（3）20～40 parts of water mixing and stirring of middle interpolation, obtain high-early strength concrete slurry.
The emphasis of the present invention mainly has following three points：
1. early-strength employ lithium carbonate and calcium formate compound system, when normal concrete goes for higher intensity
Between long.The present invention is compounded with calcium formate using the lithium carbonate with good early strong effect, and concrete can be made to obtain at short notice
Higher intensity, quickly resumes traffic；
2. the present invention adopts boric acid and tartaric acid to compound as retarder, relies on the retarding effect that boric acid and tartaric acid compound, can
To ensure that there is enough engineering times；
3. the present invention, using 80-120 mesh quartz sand, flyash and Calx as gathering materials, relies on quartz sand diameter less, flyash
And the filling up it is ensured that having preferable intensive after concrete curing of Calx, improve the intensity of concrete come to meet bridge,
The application such as harbour and military project repairing
Beneficial effects of the present invention：The correlation technique that the present invention can solve the position such as bridge, harbour and military project road rapid repair is asked
Topic.The high-early strength concrete that the present invention provides, can rapid construction, after normal construction, room temperature can reach within two hours early strong, can
Quickly resume traffic, after solidification 12h, test comprcssive strength is more than 30MPa.This high-early strength concrete can be widely used for bridge, port
The road rapid repair aspect such as mouth and military project.
