Abstract
The invention has supplied a low alkalinity ecological concrete and its two application modes: grass-planting and grass-planting. It is prepared by natural cobble stone with large diameter, high alumina cement with high and other raw materials, has lots of holes inside, water permeability and gas permeability performance, low PH value, can be used for plant grass by adding addition, as well as break down and eliminate contamination from water by using its physical, chemical and biochemical effects. It can be applied for kinds of bank protection, water permeability road, parking lot and revetment protection.
Description
Technical field
The present invention relates to a kind of low alkalinity ecological concrete, can be used for greening vegetation.
Background technology
Eco-concrete is a kind of novel concrete, and Chinese scholars just proposes this notion from eighties of last century the nineties, and begins one's study.Comparatively speaking, the research of Japan is more deep, and has obtained some gratifying achievements, and begins in practice to use, but costs an arm and a leg.Eco-concrete is mainly used in sewage disposal, water-permeable road, shore protection and bank protection etc.Through the effort of decades, the city point-source pollution control of China wins initial success, and the non-point pollution problem more and more is subjected to people's attention.Improving the area on urban water-through ground, is the effective measure of control urban non-point source pollution.Traditional shore protection and bank protection mainly are to adopt concrete to protect.This mode has not only been destroyed original physical environment, and ecotope is further worsened, and cost is higher, and landscape effect is poor.
Summary of the invention
Destroy natural landscape in order to overcome available coagulation soil shore protection and bank protection, deficiency that can not greening vegetation the invention provides a kind of low alkalinity ecological concrete that can be used for shore protection, water-permeable road, bank protection.
The technical solution adopted for the present invention to solve the technical problems is: select following raw material for use: cement, pebbles, water reducer and water prepare eco-concrete; Used in addition cement is high-alumina cement, not only have low pH value, and itself has purifying water effect simultaneously.
After usefulness of the present invention is to add additive, can plant plant on this eco-concrete, beautify view, be beneficial to the eubiosis, can utilize this natural cleaner of plant again, reduce pollution load effectively.The low alkalinity ecological concrete raw material of present patent application is easy to get, and is cheap.
Below in conjunction with drawings and Examples the present invention and working method thereof are further described.
Description of drawings
Fig. 1. the structure pattern of straw-planting type urban green space
Fig. 2. the structure pattern of non-straw-planting type water-permeable road
Embodiment
Low alkalinity ecological concrete is characterized in that being made up of cement, pebbles, water reducer and water, and concrete proportioning is: water: cement: water reducer: pebbles=0.20～0.40: 1: 0～2.5%: 5.0～10.0.
In above-mentioned materials: cement is selected high-alumina cement for use, the cement aluminium acid salt cement CA-50 of the embodiment of the invention, and the maximum characteristic of this cement is that its pH is lower; Pebbles is that size is 10～30mm natural cobblestone; Water reducer is selected the sulfonated lignin water reducer for use, not only can save cement consumption, and can reduce the initial stage hydration heat, improves concrete ultimate compression strength.In addition, can in cement, add mineral color according to actual needs, produce colored eco-concrete.
Embodiment: the ecological revetment (unit of each material: Kg/m among the embodiment
3)
(1) water 75, CA-50 aluminate cement 250, pebbles 1440, sulfonated lignin water reducer 0.625, straw 2.5 are mixed, stir with stirrer.
(2) mixing material that stirs is joined in the prefabricated template, and vibrate.
(3) vibrate finish after, carry out maintenance by control condition.
(4) maintenance after 8 hours is dismantled mould, continues maintenance 28 days, and building block completes.
(5) the straw-planting type eco-concrete according to Fig. 1 makes up pattern, according to natural grade, rests and reorganizes, and the layer overlay geotextile is placed on prefabricated building block on the geotextile more then.
(6) according to claim 3, additive preparation, and additive is filled in the natural hole of eco-concrete building block; Broadcast grass seeds, be covered with the thick nutrition soil of 1-5cm again, water seasoning; 1-2 is the grass seeds germinating growth after week.
Claims (3)
1. a low alkalinity ecological concrete is characterized in that, it is to be prepared from by high-alumina cement, pebbles, water reducer and water, and concrete proportioning is: water: cement: water reducer: pebbles=0.20～0.40: 1: 0～2.5%: 5.0～10.0; As the application model of this low alkalinity ecological concrete, straw-planting type and non-straw-planting type are arranged, straw-planting type needs doping and nutrition soil.
2. straw-planting type low alkalinity ecological concrete according to claim 1 is characterized in that pouring into 0.01-0.02m in the space of eco-concrete
3/ m
2Additive, additive formulations is: water: native naturally: peat: slow release fertilizer=1: 0.1～0.3: 0.1～0.2: 0.001～0.002.
3. straw-planting type low alkalinity ecological concrete according to claim 1 is characterized in that the top of eco-concrete covers 1-5cm nutrition soil, and nutrition soil prescription is: native naturally: peat: slow release fertilizer=1: 0.5～1.5: 0.001～0.002.
