Description
Technical field
The invention belongs to building material technical field, more particularly to a kind of method for improving scrap glass powder hydration activity.
Background technology
With the continuous development and the improvement of people's living standards of economic industry, glass be widely used in building,
The numerous areas such as instrument and equipment, scientific research, chemical industry and daily life, at the same time, the yield of scrap glass also increasingly increase
Add.According to the United Nations's data statistics, it is scrap glass that global industry waste residue, which has 7%, U.S.'s output scrap glass about 11,500,000 in 2010
T, recovery utilization rate 27%, Chinese cullet year output about 10,400,000 account for the 3%-5% of domestic waste, and utilization rate is only
13%, Hong Kong year output about 13.7 ten thousand, 96.7% is handled with garbage loading embeading, and many national glass utilizations in Europe are more than 60%,
Wherein Germany and Switzerland are more than 90%.Compared with developed countries, in starting evening, comprehensive utilization of resources rate is low for China, substantial amounts of useless
Abandon glass effectively not reclaimed and utilized, because scrap glass is non-biodegradable material, it is difficult to by following naturally
Ring and in general physics, chemical mode are acted upon and decomposed, and it not is a good method thoroughly solved to be filled, not only
Understand land occupation resource and the destruction of ecological environment can be caused.Glass is right in itself containing 70% or so amorphous silica
Its physics and chemical modification, it can effectively excite the pozzolanic activity and gelling of scrap glass itself.
The content of the invention
Present invention aims at provide a kind of method for improving scrap glass powder hydration activity.On the one hand, with scrap glass
Part substitutes cement and prepares concrete and cement products, can reduce the consumption of natural resources, promotes scrap glass recovery sharp again
With providing a sustainable approach to development for increasingly increased scrap glass；On the other hand, modern concrete itself can be made up
Defect, promote the development of diversification concrete.
Concretely comprise the following steps：
（1）By the different colours, the scrap glass of species that are collected into from salvage station it is cleaned, dry, preliminary broken, Hubei Province formula
Broken and ball mill grinding 60-120 minutes are handled, and obtain scrap glass powder.
（2）By step（1）For scrap glass powder after processing through dry screen, wet screening and sedimentation, it is 10-75 to obtain particle size range
μm waste glass powder, the specific surface area of waste glass powder particle is more than 400m2/kg。
（3）By step（2）Resulting waste glass powder adds cement and composite exciting agent carries out mix grinding and handled 30 minutes, then
Water is added, agitator for cement mortar stirring 2-3 minutes is poured into, produces composite gelled material, the fineness standard of composite gelled material
It is more than 400m for specific surface area2/kg；Each component parts by weight are：10-65 parts waste glass powder, 35-90 parts cement, 25-50 parts are originally
Water and 2-5 part composite exciting agents, wherein composite exciting agent composition are：Mass percentage content be 25%-50% sodium metasilicate and
50%-75% sodium sulphate.
（4）By step（3）The slurry of gained is inserted in test specimen, and standard curing is to regulation age and tests.
Because energy-rich bond component is more in scrap glass powder, crystal structure is firm, and it is more to break energy needed for covalent bond.Cause
This, mixing scrap glass arogel gel material has that early strength is relatively low, the features such as degree of hydration is slower.And present invention use machinery-
The common exciting means of chemistry, destroy scrap glass powder particles tetrahedral network structure, excite the potential Pozzolanic feature of scrap glass powder
And gelling, so as to promote composite gelled material heat evolution velocity, improve composite gelled material intensity.In addition, made in the present invention
, more can be effectively scattered in composite gelled material with 75 μm of scrap glass particle ﹤, play compacting effect and micro aggregate effect.Meanwhile
The incorporation of scrap glass also has following benefit：
（1）Scrap glass cost is cheap, easily collecting, and the present invention provides an economy, efficient technological process（It is not required to distinguish and gives up
Abandon color, species of glass etc.）, technical support is provided for the recycling of scrap glass.
（2）The recycling of scrap glass, it can reduce and stack area, reduce the energy consumption of cement, reduce titanium dioxide
The discharge of carbon, there is great economic value and environmental protection meaning.
（3）The incorporation of scrap glass, the total thermal discharge of composite gelled material can be reduced, avoid its internal temperature exceed limitation and
Formed compared with large inner tension and more microcrack.In addition, the compacting effect and micro aggregate effect of small scrap glass powder, right
The strength development of composite gelled material plays positive contribution.
(4) composite gelled material of the invention has rapid hardening speed firmly, and early strength is higher, the spy that later strength increases substantially
Property.
