Abstract
The present invention be a kind of using coal gangue subculture for part stone as the freeze proof plant cover concrete of coarse aggregate, can be applicable to the engineerings such as the road of northern area, river course, reservoir slopes protection, massif reparation, belong to field of constructional engineering material.The present invention is not mainly when affecting intensity and porosity, it is determined that coal gangue subculture is for the optimum mix amount of stone；And take appropriate measures and make it meet the northern area requirement to concrete antifreezing, it is determined that go out the proportioning of the best and best admixture dosage etc..This plant cover concrete, can effectively solve a difficult problem for northern China cold district in winter side slope protection and the drawback of traditional bank so that it is can growing plant, reach greening purpose；Make full use of garbage gangue simultaneously, the problem solving its bulk deposition land occupation resource pollution environment, reduces the use of stone, reduces cost, protect resource.Carry forward vigorously under the overall background of energy-conserving and environment-protective in China, have comparatively wide popularizing application prospect.
Description
(1) technical field
The present invention relates to the concrete of road, river course, reservoir slopes protection and massif reparation etc., belong to field of constructional engineering material.
(2) background technology
Green and ecology are increasingly emphasized in current road, river course, reservoir slopes and breakage mountain body reparation etc., traditional slop protection material has been difficult to meet requirement, it is primarily present problems with: although 1. coagulation great soil group bank protection and stone pitching material have the advantages such as intensity height, good endurance, but its surface texturisation is brittle, rough surface, color is gloomy simultaneously, and visual effect lacks life, the space constructed by it gives thick, hard, cold, dark sensation, and green vegetation cannot grow thereon；Although 2. hole type slop protection material structure manufacture is relatively easy and have certain afforestation effect, but can green coverage less, hole diameter is big simultaneously, and in hole, soil exists and anti-wash pick property difference and the shortcoming such as be easy to run off.3. simple slope vegetation protection technology afforestation effect is good, plants raw base material and has certain intensity, but experience rainwater soaks for a long time and washes away and is easy to run off, caves in, and loses protective capacities.4. plant cover concrete technology develops to some extent in China, but anti-freezing property is poor, and cold district is substantially inapplicable.
The gangue that current colliery abandons is the solid waste discharged in driving, exploitation and coal washing process.It is the mixture of carbonaceous, shale and arenaceous shale, there is low heating value.China has accumulated over the years gangue about 1000 megatons, and continues to discharge about 100 megatons every year, not only piles up occupation of land, and can also spontaneous combustion contaminated air or cause fire.Gangue is primarily used to produce the construction materials such as spoil cement, concrete aglite, refractory brick.
The weak point of present project post-evaluation technology is a lack of ecological effect, but it is only that opposite side hill start is to propping up the effect that gear is reinforced, and slope vegetation protection ecological effect is notable, but antiscour, anti-immersion ability, so academic circles at present and engineering circles are when considering slope vegetation protection, it is not only unilaterally accomplish slope greening or slope reinforcing, but engineering protection and vegetative protection are combined.Meanwhile, that widens gangue utilizes channel and consumption, and the series of problems produced for solving gangue plays very important effect.
(3) summary of the invention
It is an object of the invention to provide a kind of freeze proof plant cover concrete, coal gangue subculture is utilized to replace part stone as the coarse aggregate of plant cover concrete, take corresponding measure to increase the performances such as its freeze proof, resistance to compression simultaneously, and take measures to reduce its pore water alkalescence so that it is be suitable for plant growing.
The present invention is achieved through the following technical solutions: the match ratio of this plant cover concrete, after determining many group testing programs by orthogonal test, and the indexs such as the resistance to compression of concrete sample, folding freeze proof, anti-, water permeability, porosity are tested, the experimental data obtained vertically and horizontally is compared, finally determines that the percentage by weight of each raw material of this invention is calculated as: cement 10% 15%；Common rubble stone 32% 42%；Gangue stone 32% 42%；Water 2% 5%；Sand 3% 6%；Water reducer 0.06% 0.1%；Polypropylene fibre 0.03% 0.08%；Air entraining agent 0.0008% 0.0012%；108 glue 0.8% 1.2%.Under this match ratio, concrete intensity, water penetration, porosity and anti-freezing property are best, it is possible to engineering demands, and have reached saving stone consumption, fully and in a large number utilize the purpose of gangue.
The present invention can effectively solve a difficult problem for cold district side slope protection in winter and the drawback of traditional bank, makes full use of garbage gangue simultaneously, solves its problem such as bulk deposition land occupation resource and contaminated environment; reduce the use of stone; reduce engineering cost, protect resource, beautify the environment.Carry forward vigorously under the overall background of energy-conserving and environment-protective in China, have comparatively wide popularizing application prospect.
(4) detailed description of the invention
The detailed description of the invention of this invention is: first cement, sand, logical rubble stone, gangue stone, polypropylene fibre, sand, air entraining agent is added by weight percentage before construction, is sufficiently stirred for, is dissolved in by water reducer in water and adds, be sufficiently stirred for 3 minutes.
The embodiment gangue freeze proof plant cover concrete of stone coarse aggregate
Cement: 42.5 grades of Portland cements, percentage by weight is 10% 15%；
Sand: medium sand, modulus of fineness 2.67, comply with the national standard requirements, percentage by weight is sand 3% 6%；
Rubble: particle diameter is the discontinuous gradation limestone gravel of 16mm～25mm, complies with the national standard requirements, percentage by weight is 32% 42%；
Gangue: particle diameter is the discontinuous gradation rubble of 16mm～25mm, complies with the national standard requirements, percentage by weight is 32% 42%；
Air entraining agent: adopt commercially available AH-1 air entraining agent, percentage by weight is 0.0008% 0.0012%；
Water: tap water, percentage by weight is 2% 5%；
108 glue: commercially available cement mortar 108 glue, percentage by weight 0.8% 1.2%；
Polypropylene fibre: be the chopped fiber of length 6mm, percentage by weight 0.03% 0.08%；
Water reducer: comply with the national standard requirements, percentage by weight is 0.06% 0.1%.
During construction, the interpolation of each raw material also can be implemented by weight.
Stir with blender, be subsequently used for the construction of engineering.Form of construction work can adopt cast in situs form, or adopts preformed patterns；Large-scale water conservancy channel building or large-scale road slope adopt the form of precast slab；Small-sized building adopts cast-in-place form.
The present embodiment fully meets the northern area requirement to side slope protection, resistance to compression, the requirement that freeze proof, hole all can meet Practical Project, is more suitable for the side slope protection of cold district.Solve all drawbacks of traditional bank well, allow and grow plant in concrete, ecological revetment and structure bank protection are combined togather, there is good social benefit, ecological benefits and economic benefit.
