Description
Technical field
The present invention relates to a kind of machine-made sand concrete materials, and in particular to a kind of lightweight concrete material of architectural prefab
And preparation method thereof.
Background technique
With the continuous development of reform and opening-up, the little expansion of national basis construction, the demand of commerical ready-mixed concrete is continuous
Increase.The demand of the yellow ground in concrete is constantly increased thereupon.Currently, the sand in most of China area is natural
Sand.But with continuing to increase for infrastructure step, natural sand resource is increasingly reduced, and Sand for Concrete conflicting requirements are increasingly prominent
Out.Requirement with high performance concrete to aggregate is continuously improved.Good yellow ground is fewer and fewer.Only with Shanghai City for, every year
The demand of commerical ready-mixed concrete is calculated by 15,000,000 sides, and 10,000,000 tons or so of annual demand yellow ground.Urgent need has new substitution
The material of yellow ground, to solve the use sand contradiction of current concrete.
Summary of the invention
In consideration of it, the present invention provides lightweight concrete material of a kind of architectural prefab and preparation method thereof, Ke Yi
Yellow ground use is substituted under the premise of proof strength completely.
Thus, on the one hand, the present invention provides a kind of lightweight concrete materials of architectural prefab, including foamed cotton layer and packet
The concrete layer being overlying on outside foamed cotton layer, concrete layer include the material of following weight percent:

Further, the fineness of above-mentioned Machine-made Sand is 3.4.
Further, the fineness of above-mentioned ultra fine sand is 0.9.
Further, above-mentioned additive is middle iron Aurion spy's high efficiency water reducing agent.
On the other hand, the present invention provides a kind of preparation method of the lightweight concrete material of architectural prefab, features
It is, above-mentioned each component material is mixed and stirred into concrete layer.
The lightweight concrete material and preparation method thereof of a kind of architectural prefab provided by the present invention, by improved
Material and preparation method, using mechanism sand and new proportion, so that intensity requirement is fully achieved in the concrete material of preparation, it can be with
Concrete of the substitution based on yellow ground completely.
Specific embodiment
The exemplary embodiment of the disclosure is described in more detail below.Although showing the exemplary implementation of the disclosure
Example, it being understood, however, that may be realized in various forms the disclosure and should not be limited by the embodiments set forth herein.On the contrary,
These embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can communicate completely to the scope of the present disclosure
Those skilled in the art.
The following are a kind of lightweight concrete materials of architectural prefab provided in an embodiment of the present invention and preparation method thereof, should
Machine-made sand concrete material is obtained by following proportion, and total weight is in terms of 500KG.
The preparation of the machine-made sand concrete material only needs to be mixed and stirred referring to common concrete making technology.
Wherein, cement, miberal powder composition ratio can be 4 to 6 or 5 to 5.
Meanwhile mechanism grain fineness number therein is 3.4, ultra fine sand fineness is 0.9, stone fineness is 5-25, additive is specific
Iron Aurion spy high efficiency water reducing agent, cement, miberal powder composition specifically use conch P.II.52.5. in.
Experimental data table:
