Building block has carried out numerous studies, from raw material selection, formula design, pouring stability, production technology, the mechanical property of product,
The modification of water imbibition, dry shrinkage, durability, carbonation properties to product, forms more mature preparation process.Although powder
Coal ash aerated-block has gradually formed stable preparation process, but its low strength, brittleness are big, water absorption rate is higher, freeze thawing resistance
Property it is poor, carbonization ability is low, drying and watering cycle is poor, build a wall after be easy cracking generate crack.
Quartz tail sand grindability is poor, and crystal structure is fine and close, and hydration reaction activity is low, causes tailings effective rate of utilization relatively low,
It exists simultaneously the unrecovered utilization of slug and is also easy to produce secondary pollution problems.Researcher only has studied dry density and pressure resistance
Degree, and the performances such as the physicochemical property to quartz tail sand, the frost resistance of pozzolanic activity and aerated-block, water imbibition, carbonation properties
Index lacks the evaluation of science, also studies pouring stability, the quiet crucial technical parameter such as maintenance and steaming pressuring curing system that stops
It is very few.In addition, B05 grades most or more products, intensity is lower, and thermal coefficient is larger, and is also easy to produce the defects of cracking is heaved.
Zheng Wenxin uses activator to prepare B06 as siliceous raw material to after the activity of gold tailings pre-activate processing excitation tailing
Grade aerated-block；Wang Changlong et al. is prepared for density as silicon source using the levigate Low-silica iron ore tailings addition high silicon raw material in part
637kg/m3, compression strength be 4.31MPa aerated-block；Qian Jiawei prepares B06 grades using the silica sand of copper tailing substitution 32%
Aerated-block；Xiao-yan Huang et al. prepares steam-pressing aero-concrete using copper tailing and blast furnace slag, because this two
SiO in kind raw material2, CaO and content of MgO it is higher, can meet the needs of calcareous raw material without adding quick lime, reduce lime
The calcining of stone.But content of MgO is excessively high in raw material, because its digestion is extremely slow, can continue after green body hardening or during steam pressure
Digestion, causes volume expansion and destroys green body.Tailing class aerated-block is conducive to the recycling and reusing of tailing, makes to solve tailing
At environmental problem provide beneficial reference, but because following reason makes tailing matter aerated-block be only at experiment rank
Simultaneously industrialized production is not implemented in section.First is that tailings particles are thicker, needed before use levigate active to improve its；Second is that tailing contains
Some mineral species are complicated, and the quartzy state SiO contained by it2Seldom, most of SiO2It is present in all kinds of mineral, activity is low,
It need to be activated using activator.
The partial size of ceramic waste residue is tiny, D50Only 11.96 μm.It is analyzed in terms of reactivity, this obviously can increase instead
Area is answered, is conducive to improve SiO2Dissolution rate, accelerate SiO2With reacting for CaO, guarantee is provided for product strength.But from
Analysis in terms of influence to material preparation, since waste ceramic ground-slag is too thin, slurry thickening is fast, and viscosity is big, will certainly hinder aluminium powder
It gets angry pore-forming, it is difficult to guarantee pouring stability.Traditional flyash and the generally existing intensity of quartz sand steam-pressing aero-concrete is low,
The defects of thermal coefficient is high, anti-freezing property is poor has easily occurred drum, cracking and decortication etc. in use and has seriously affected building matter
The problems such as amount and service life, let alone applied in terms of Self-thermal-insulation System and load-bearing.
