Description
Technical field
The present invention relates to the preparation methods of a kind of concrete and its product, and in particular to a kind of room temperature maintenance alkali-activated carbonatite gelling
The preparation method of material pervious concrete and its product belongs to field of material technology.
Background technology
For China cities and towns, currently and from now on the development of a period of time, government will propose the mesh for building sponge city
Mark, it is so-called to build " sponge city ", exactly city is built up can absorb water when rainy, water storage, infiltration, water purification, drying season
The water " release " stored when needing is out used.Thus, for the construction material built used in " sponge city ", also need
Show this function of saving-discharge water, such as ground surface material.It develops with excellent infiltration, resistance to compression, wear-resisting, anti-skidding
Performance and environmental protection, beauty, comfortable easy care simultaneously can sound-absorbing noise abatement etc. by be industry research and development target, have and save-discharge water work(
The road construction material of energy, will make town pavement also can effectively alleviate city while as the landscape road surface of " can breathe "
Tropical island effect makes urban pavement no longer generate heat.
Permeable concrete is sponge urban pavement material more satisfactory at present.Common cement pervious concrete pavement
Brick has higher intensity, wearability and durability, is typically matched by raw material such as cement, sand, stone, water according to certain
Than pouring or compression moulding and being obtained through maintenance to regulation age.
The present inventor is intended to the pervious concrete for being substituted traditional cement using alkali-activated carbonatite cementitious material and being prepared high intensity
And road surface tile product, be resource using waste coal ash, slag etc., given full play in terms of environmental protection take on while, system
The standby product for providing higher-strength, wearability and durability.
Invention content
It is an object of the present invention to provide a kind of alkali-activated carbonatite cementitious material pervious concrete and preparation method thereof, including step：
1) each material is taken by mass percentage：4~12% high-calcium fly ass, 6~18% miberal powders, 0~3% silicon ash, 4~
8% cement, 5~15% water, 60~80% single particle size aggregates, 1~3% alkali-activator, 0~2% polycarboxylate water-reducer；
2) water of single particle size aggregate and total Water 20%-30% is added in blender, stirred 30 seconds；Then successively
The water of cement, miberal powder, high-calcium fly ass, silicon ash and remaining 60%-70% are added in, continues stirring 90 seconds；Alkali is eventually adding to swash
Agent and polycarboxylate water-reducer are sent out, is further continued for stirring 2 minutes, celluar concrete is formed；
3) celluar concrete for obtaining step 2) is encased in two times in mold, using artificial plus mechanical concrete vibrating mode into
Type；
4) continue band mold after being molded to conserve, until form removal after 24 hours；
5) it uses after form removal and is conserved, and once concrete surface is kept to moisten every 8 hours shower waters under normal temperature condition；It supports
Shield to 28 day age obtains pervious concrete finished product of the present invention.
The alkali-activator is the water glass solution of 1.2 moduluses, and suitable modulus of water glass is allocated using granular NaOH.
The single aggregate size is preferred：4.75-9.5 millimeter；
The single aggregate is preferred：Stone in nature.
The advantages and features of the present invention：
1. alkali-activated carbonatite porous concrete product has many advantages, such as the porosity of higher-strength, high coefficient of permeability and stabilization.
2. with higher wearability and durability.
3. making full use of flyash, slag the like waste, waste is made to be converted into resource.
Specific embodiment
For a better understanding of the present invention, with reference to embodiment, the present invention will be further described, but embodiment is not right
The present invention is construed as limiting.
The material that embodiment and comparative example use is as follows：
The Portland cement of the PO42.5 grades in Tianjin development cement plant, the production of Tianjin Bo Di chemical inc
Sodium silicate solution, modulus 3.3, Baume degrees 40, the content of Na2O is 22.8-23.5%.This experiment uses modulus
For 1.2 waterglass, the waterglass of this modulus is prepared with sodium hydroxide.Single particle size aggregate be stone, grain size 4.75-
9.5mm。
Embodiment：
Take by mass percentage 4.8% high-calcium fly ass, 7.2% miberal powder, 0.3% silicon ash, 5.3% portland cement,
71.56% stone, 9.4% water, 1.26% waterglass, 0.18% polycarboxylate water-reducer.
First the water of stone and total Water 20%-30% is added in blender, is stirred 30 seconds；Then water is sequentially added
Mud, miberal powder, high-calcium fly ass, silicon ash and remaining 60%-70% water, continue 1 point of stirring 30 seconds；Be eventually adding waterglass and
Polycarboxylate water-reducer is further continued for stirring 2 minutes, and celluar concrete is formed；The alkali-activated carbonatite cementitious material that this is stirred is permeable mixed
Solidifying soil is encased in two times in three gang moulds of 100 × 100 × 100mm, using manually plus machinery vibrates molding.
Continue band mold after molding to conserve to 24 hours, form removal；Since this pervious concrete is alkali-activated carbonatite, using water curing
It easily generates alkali to be precipitated, so keeping concrete table using maintenance under normal temperature condition after form removal and every water of 8 hours sprays
Face moistens；Maintenance to 28 day age obtains pervious concrete finished product of the present invention.
Comparative example
The preparation method is the same as that of Example 1, and difference part is that raw material are only cement, stone, polycarboxylate water-reducer, water.
Test result compares：
The pervious concrete prepared to embodiment and comparative example carries out performance detection, and testing result is as shown in the table：
