Description

A kind of non-burning brick preparation method of durable slag micropowder and clay
Technical field：
The present invention relates to the non-burning brick preparation method of a kind of durable slag micropowder and clay of building material field.
Background technology：
Building engineering construction efficiency can be improved using cement and concrete product, after concrete cast, if hot climate, It is air-dried, is conserved not in time, the evaporation of concrete reclaimed water branch is too fast, forms dehydrating phenomena, can make to have formed gelinite Cement granules can not abundant aquation, it is impossible to be converted into stable crystallization, lack enough cohesive forces, so as to can be in concrete table There is sheet in face or powdery comes off, in addition, when concrete not yet possesses enough intensity, the too early evaporation of moisture can also produce , there is cup shake in larger contraction distortion, influences the durability and globality of concrete.Therefore increase in concrete strength Phase, in order to obtain enough intensity within a short period of time and accelerate mould turnover, while ensure the intensity of concrete, durability etc. Technical indicator, generally it is conserved.Traditional concrete curing method has natural curing, atmospheric steam curing and high temperature high Pressure maintenance etc..It is longer the time required to natural curing, and quality is difficult to ensure that；Scientific and reasonable steam curing system in atmospheric steam curing It is to produce one of important prerequisite of high quality cement concrete product with technique, maintaining process, which is generally divided into, quiet to stop, heats up, be permanent Temperature, 4 stages of cooling, in order to prevent product from causing concrete to produce crack because internal-external temperature difference is excessive or thermostat temperature is too high, Must strictly control it is steam-cured during heating-cooling speed and thermostat temperature etc., process very complicated and require strict, condition control Make and bad be easy for causing concrete product not reach preparation technology requirement；And HTHP curing condition requires higher, lead to Often critical shortage, its exacting terms limit its application to the various resources in many construction places.
The defects of conventional method, is increasingly difficult in adapt to modern construction needs, and therefore, people investigated concrete and support The new material and technique of shield, granulated blast-furnace slag are blast-furnace cinders by a kind of with very high potential obtained from the chilling of water The vitreous structure material of activity, slag micropowder, slag fibre, builds the road in slag cements, concrete admixture in recent years Filler etc. obtains very big utilization, and the enhancing of concrete and rebar cohesive force, late strength of concrete mixed with slag micropowder carry The high, good characteristics such as prevent shrinkage cracking, concrete basicity low, are the stocks for preparing high performance concrete, 2011 years China's iron and steel output reaches more than 68.3 hundred million tons, can discharge nearly 2,000,000,000 tons of granulated blast-furnace slag, the money of granulated blast-furnace slag Sourceization can also greatly reduce occupation of land and environmental pollution using the energy is saved while reducing production cost, produce preferably warp Benefit of helping and social benefit.Although the research of slag micropowder improves the concrete performances such as intensity, workability, cohesive force, from Do not improved angularly from the resources conservation such as steam curing time and condition, the input of high-tension apparatus, production efficiency.How to enter One step improve the lateral reactivity of slag micropowder, increase its feature, to expand its application field critically important as one in industry Research topic.
