Abstract
The invention relates to permeable concrete and a preparation method thereof, which belong to the technical field of the utilization of solid wastes and building materials. The permeable concrete of the invention is prepared by the following steps of: preparing a composite gel material for later use, namely, weighing, stirring and mixing 70 to 88 weight percent of cement, 10 to 30 weight percent concrete powder and 1 to 5 weight percent of emulsion powder; and then preparing the permeable concrete, namely, fully and uniformly stirring 10 to 25 weight percent of composite gel material, 70 to 85 weight percent of recycled concrete aggregate and 4 to 9 weight percent of water. The permeable concrete prepared by the method has the characteristics of the coefficient of water permeability of more than or equal to 2 mm/s, the compression strength of more than or equal to 20 MPa, and the application to the ground of sidewalks, squares and parks.
Description
Technical field
The present invention relates to a kind of pervious concrete and preparation method thereof, belong to solid waste utilization and building material technical field.
Background technology
Along with the development that urban modernization is built, the city is covered by Steel Concrete, and the waterproof pavement respiratory is poor, can't permeate rainwater.At present, life and process water are still take underground water as main, and excessive exploitation makes ground water table sharply descend, and the ecological beginning in earth's surface is unbalance, and environmental problem is more and more serious.Pervious concrete is the Eco-friendly concrete, and pervious concrete has vesicular structure, characteristics that porosity is large, can permeate rainwater, increases urban groundwater resource, improves urban climate, protection of the environment.Pervious concrete can be widely used in road and parking lot etc. in square, walkway, park.
Concrete need of production uses cement and consumes natural crystal.A large amount of exploitations and the use of natural crystal can cause soil erosion and natural landscape to worsen, and have a strong impact on the Sustainable development of society, the existence that even jeopardizes the descendants.According to incompletely statistics, China's annual building waste that produces at present reaches 100,000,000 tons of left and right, and the building castoff of long-term accumulation will be up to several hundred million tons.Building castoff being recycled, replaced the part natural resource to produce material of construction and pervious concrete, is to protect national resource, and improves environment, an important channel of Promote Sustainable Development.
Summary of the invention
The object of the present invention is to provide a kind of pervious concrete and preparation method thereof.
The preparation method of a kind of pervious concrete of the present invention is characterized in that having following preparation process and step:
A, at first prepare composite gelled material, the raw material of this composite gelled material forms and weight percent is:
Cement 70～88%;
Concrete ash 10～30%;
Latex powder 1～5%;
Wherein: described cement is 42.5 or 52.5 grades of ordinary Portland cements;
Described concrete ash is discarded concrete levigate fine powder more after crushed, its specific surface area 〉=500m
2/ kg;
Described latex powder is any in styrene-propene phenol latex powder, Acrylic emulsion powder, vinyl acetate-ethylene latex powder; Fineness is 100 orders;
According to the weighing of above-mentioned raw materials proportioning, join respectively in mixing machine, through stirring, namely obtain composite gelled material;
B, preparation pervious concrete; Pervious concrete raw material used forms and weight percent is:
Composite gelled material 10～25% described above;
Aggregate of recycled concrete 70～85%;
Water 4～9%;
Described Aggregate of recycled concrete is that discarded concrete also cleans through pulverizing, remove impurity, and its grain diameter is between 5～10mm;
According to the proportioning weighing of above-mentioned raw materials, it is joined respectively in stirrer, through stirring, can realize cast, smooth, maintenance processes, obtain a kind of pervious concrete.
The features and advantages of the invention are as described below:
1, the pervious concrete of the present invention's preparation has good water-permeable, ventilation property and ultimate compression strength, can play the increase urban groundwater resource, regulates urban climate, the effect of improving the ecological environment.
2, the present invention utilizes discarded concrete to do aggregate, replaces natural gravel, utilizes discarded concrete to prepare the concrete ash and makes concrete gel material, has greatly improved the added value of discarded concrete, reduces the exploitation to natural rock, reduces the production cost of pervious concrete.
3, the present invention can be prepared into a kind of composite gelled material to cement, concrete ash, latex powder in proportion, is convenient to transportation.When producing pervious concrete, can utilize equipment and the silo of producing normal concrete, add aggregate and water just can be prepared pervious concrete easily by proportioning.
