Abstract
The invention relates to green high-performance concrete with superfine oil palm fruit shell ash. The concrete comprises the components including cement and the like, wherein the cement is replaced by 20-60% by mass of oil palm fruit shell ash and the like. The concrete has the beneficial effects that waste materials generated in the palm oil refining industry are sufficiently utilized, the waste materials are appropriately treated and doped into the concrete, in such a mode, both the influence of industrial waste material discharge and stacking on the environment is alleviated, and the defects of the conventional cement and concrete industry are effectively reduced, and a concrete material has high performance and is environment-friendly.
Description
Technical field
The present invention relates to green construction material field, especially a kind of GHPC that comprises ultra-fine oil palm shell ash.
Background technology
Conventional concrete industry is because consuming the valuable natural resources of flood tide and fossil oil, discharge flood tide greenhouse gases, dust and solid waste and quite denounced.In order to adapt to the strategy of sustainable development and the state basic policy of building a conservation-minded society, to change, take the traditional economy growth pattern that high energy consumption, heavily contaminated be cost, concrete technology and industry must be towards the future developments of environmental protection and energy saving, green low-carbon.The industrial and agricultural wastes such as flyash, graining blast-furnace cinder micro-powder, silica flour, rice hull ash, metakaolin and the raw material with local characteristic are widely used in preparing concrete is one of fabulous illustration.Do like this and achieve many things at one stroke beyond doubt, can turn waste into wealth, can improve and improve concrete performance again, can also reduce seizing the destruction of ecotope and natural resources.
Oil palm belongs to perennial monocotyledons, is tropical woody oleiferous plants crop.Pulp, the kernel of oil palm are rich in grease, have the good reputation of " world oil king " in various oil crops.China introduces a fine variety the oil palm history of existing eight more than ten years, the existing ground such as Hainan, Yunnan, Guangdong, Guangxi that are mainly distributed in.Plam oil is favored by human consumer extensively because of nutritious, output is soaring steadily in recent years.When consuming a large amount of oil palm fruit during plam oil refining, also produce the waste materials such as a large amount of oil palm shells, fruit stone, these waste materials are often used as the energy and burn in refinery.Ashes after oil palm shell, fruit stone burning are oil palm shell ash, and this material is because being rich in amorphous glass body SiO
2and there is greater activity, be expected to become another novel supplementary cementitious material of preparation GHPC.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of more high workability, more high strength, better weather resistance and the GHPC that comprises ultra-fine oil palm shell ash of subenvironment negative effect are more provided.
The present invention solves the technical scheme that its technical problem adopts: this GHPC that comprises ultra-fine palm hull ash, comprise the components such as cement, and described cement is replaced by the quality such as oil palm shell ash 20%～60%.
As preferably, described oil palm shell ash is processed and is obtained by the following method: residual former ash after oil palm shell burning is placed in to the square hole sieve of drying at the temperature of (105 ± 5) ℃ to crossing 0.3mm aperture after constant weight, screen out coarse particles and difficult combustion impurity, and then used ball mill levigate so that fully calcined; Afterwards levigate rear oil palm shell ash is placed in to the temperature lower calcination 90min of (500 ± 5) ℃, is intended to remove the uncombined carbon that affects pozzolanic activity wherein comprising; Finally again levigate to calcining rear oil palm shell ash, make it specific surface area and be not less than 1.65m
2/ g.
As preferably, the component that is replaced every cubic metre of concrete before cement by quality such as oil palm shell ashes is: 540kg cement, river sand 735kg, rubble 1044kg, water 135kg and superplasticizer 15kg.
Inventing useful effect is: the present invention makes full use of the waste material that plam oil refining industry produces, it is suitably mixed in concrete after processing, this way had both alleviated industrial waste discharge and had piled up the impact on environment, many drawbacks of effectively having alleviated again traditional cement, the existence of concrete industry, make the further high performance of concrete material and greenization.
Embodiment
Below the invention will be further described:
First the former ash of oil palm shell is placed in to the square hole sieve of drying at the temperature of (105 ± 5) ℃ to crossing 0.3mm aperture after constant weight, screened out coarse particles and difficult combustion impurity; Then use ball mill levigate so that fully calcined; Afterwards levigate rear oil palm shell ash is placed in to the temperature lower calcination 90min of (500 ± 5) ℃, is intended to remove the uncombined carbon that affects pozzolanic activity wherein comprising; Finally again levigate to calcining rear oil palm shell ash, make it specific surface area and be not less than 1.65m
2/ g.By in addition special processing of the ashes (being the former ash of oil palm shell) to residual after oil palm shell burning, reduce its carbon content and increase fineness, thereby obtaining ultra-fine oil palm shell ash (UPFA is made in letter).
The quality (20%～60%) such as the thin brown oily shell ash of spy of usining after above-mentioned art breading replace cement mixes in concrete as supplementary cementitious material, utilizes the hydration activity of this industrial waste and micro-packing effect to prepare GHPC.
The thin oil palm shell ash of the spy equivalent that the massfraction of take is respectively 20%, 40% and 60% replaces cement and prepares GHPC.For the ease of comparing specific embodiment of the invention effect, the control group of the straight cement concrete of not mixing special thin oil palm shell ash is set simultaneously.The performance index such as described four kinds of concrete slumps, time of coagulation, ultimate compression strength, impermeability and carbon emission amount are measured, thereby reflected the improvement effect of oil palm shell ash to concrete performance comprehensively.
Starting material: cement is that strength grade is 52.5 silicate cement; Special thin oil palm shell ash is the product through art breading proposed by the invention, and its density is 2.50g/m
3, specific surface area is 1.72m
2/ g, activity index is 87%; Fine aggregate is natural river sand, and its grating is qualified, and fineness modulus is 3.0, and apparent density is 2.63g/m
3, water-intake rate is 1.33%; Coarse aggregate is granite stones, and its nominal maximum aggregate size is 12.5mm, and apparent density is 2.68g/m
3, water-intake rate is 0.46%; High efficiency water reducing agent is polycarboxylate system's product, and its water-reducing rate is not less than 20%.
Proportioning: the principle design mixture proportion being equal to according to the total consumption of gelling material (cement and ultra-fine oil palm shell ash), water-cement ratio (w/b=0.25) and aggregate consumption, refers to table 1.
Table 1 mix proportion
Performance index: as described in Table 2, for mixing the GHPC of ultra-fine oil palm shell ash, along with the raising of oil palm shell ash replacement rate (0,20%, 40%, 60%), the concrete slump, ultimate compression strength significantly increase, and impervious coefficient and carbon emission amount significantly reduce.The GHPC that ultra-fine oil palm shell ash is mixed in this explanation has more high workability, more high strength, better weather resistance and subenvironment negative effect more.But because the activity of ultra-fine oil palm shell ash is poor compared with cement, cause will grow compared with straight cement concrete its time of coagulation.
The concrete performance of table 2
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
