Abstract

The invention belongs to the technical field of biological engineering and discloses a preparation method of an antifreezing plant ecological concrete. The ecological concrete is prepared by stirring and pouring the following materials by weight: 1550-1600 parts of coarse aggregate, 180-210 parts of cement, 63-70 parts of water, 45-52 parts of silica fume, 40-50 parts of micro short fiber and 2.0-2.5 parts of a polycarboxylate superplasticizer. The formed ecological concrete has a continuous connected pore structure, compressive strength reaching above 10MPa and flexural strength of 1.5-3MPa. The concrete meets the strength need for berm and greening projects. The concrete has effective porosity reaching 25-35% and pH value reduced to about 10, and is suitable for plant growth and habitation of small animals. The ecological concrete in slow freezing environment resists the cycle of freezing and thawing to more than 50 times, has strength loss of no more than 20%, and reaches good antifreezing effect.

A kind of prepare the method that anti-freezing type plants raw eco-concrete
Technical field
Present invention relates particularly to a kind of utilize silicon ash-microdenier staple to prepare the method that anti-freezing type plants raw eco-concrete, belong to technical field of bioengineering.
Background technology
Ecology refers to the mutual relation of organism and its surrounding enviroment (including abiotic environment and biotic environment);Concrete (" concrete " be its write a Chinese character in simplified form, synonym) refer to be configured by proper proportion by Binder Materials, aggregate and water, the more artificial stone material through certain time hardening.There are broad sense and the conceptive differentiation of narrow sense in Hefei section along science and trade eco-concrete/ecological concrete.Broad sense eco-concrete/ecological concrete is defined as having certain ecological effect or the concrete of specific ecological functions, this kind of concrete is compared with conventional concrete, typically have and decrease cement consumption, there is the functions such as dedusting noise reduction, water-permeable and air permeable, water purification heat accumulation, there is environment friendly or biocompatibility.Narrow sense eco-concrete/ecological concrete has the concrete of biocompatibility and ecological effect the most exactly, wherein ecological effect can be expressed as concrete finished product can grow biology, impact biology, the biology and the concrete that are attached on concrete have dependence, refer exclusively to that there are the concrete of good biocompatibility, xoncrete structure and concrete product etc., to this end, it is proposed that a kind of utilize silicon ash-microdenier staple to prepare the method that anti-freezing type plants raw eco-concrete.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, thering is provided a kind of utilizes silicon ash-microdenier staple to prepare the method that anti-freezing type plants raw eco-concrete, can be at lake, rivers and creeks bank protection, the engineerings such as highway bank protection can either play safeguard function, greening can be played again attractive in appearance, the function of water and soil conservation, there is excellent environment compatibility, and it is cheap, production technology is easy, meet improving the ecological environment of country, save natural resources and the low-carbon economic policy of sustainable development, take into account economic benefit, social benefit and ecological benefits, have broad application prospects, can effectively solve the problem in background technology.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
The present invention provides a kind of and utilizes silicon ash-microdenier staple to prepare the method that anti-freezing type plants raw eco-concrete, described eco-concrete be by coarse aggregate 1550-1600 weight portion, cement 180-210 weight portion, water 63-70 weight portion, silicon ash 45-52 weight portion, microdenier staple 40-50 weight portion, polycarboxylate high-efficiency water reducing agent 2.0-2.5 part weight portion, material through stirring, pour molding.Eco-concrete after molding has the structure hole of continuous communicate-type, and comprcssive strength can reach more than 10MPa, and rupture strength is 1.5~3MPa.Meet it as bank protection, the intensity needs of afforestation project.Its effective drainage porosity can reach 25~about 35%, and pH value can be reduced to about 10, is suitable for plant growing and meiofauna is lived in caves.Eco-concrete is resisted freeze-thaw cycle under freezing environment slowly and be can reach more than 50 times, and its loss of strength is less than 20%, and cryoprotective effects is good.
2, a kind of utilizing silicon ash-microdenier staple to prepare the method that anti-freezing type plants raw eco-concrete, eco-concrete is preparation technology comprise the following steps:.
Step one: (1) is by the coarse aggregate prepared and microdenier staple dry mixing 1min so that it is is strongly rubbed with the hands stone roller and disperses;
Step 2: (2) add the material such as cement, silicon ash and continue dry mixing 30s, make material be evenly distributed;
Step 3: (3) are eventually adding water, additive stirring 1min30s, amount to stirring 3min.Eco-concrete directly pours after stirring at the scene, and concrete surface uses template to flatten or short time vibration flattens.Overlay film maintenance 3 days, sows grass seeds and a small amount of Nutrition Soil at concrete surface afterwards.For improving the eco-concrete slope stability to river levee, intend using plant anchoring and anchor pole (or concrete soil nail) mode to anchor river levee, depending on anchoring spacing and concrete grammar are according to practical situation.
The present invention is reached to provide the benefit that: a kind of utilize silicon ash-microdenier staple to prepare the method that anti-freezing type plants raw eco-concrete, safeguard function can either be played in the engineerings such as lake, rivers and creeks bank protection, highway bank protection, attractive in appearance, the function of water and soil conservation of greening can be played again, there is excellent environment compatibility, and it is cheap, production technology is easy, meet the low-carbon economic policy of improve the ecological environment, save natural resources and the sustainable development of country, take into account economic benefit, social benefit and ecological benefits, have broad application prospects.
