Description
Technical field
The present invention relates to a kind of mortar, especially stone powder mortar.
Background technology
In the Mineral resources, stone ore is used as raw mineral materials and building stones in a large number by a lot of industrial sectors, is mainly used in industry such as building materials, metallurgy, chemical industry, wherein with the application quantity maximum of building materials industry.In building materials industry, stone ore is mainly used in it is broken into building stones, and in the middle of shattering process, can produce the very little fine particle of a kind of particle diameter, i.e. stone flour.The limit value of content of stone powder is defined as according to concrete batching intensity in existing JGJ52-2006 " regular concrete sand, stone quality and the test method standard " artificial sand: during more than or equal to C60 for≤5%, during C55-C30 for≤7%, be≤10% during smaller or equal to C25, cause a large amount of stone flours of discharging in the building stones production to abandon.The environment that the mankind depend on for existence is not only polluted in the stacking of waste stone powder, and takies the farmland, serious waste land resources.
Summary of the invention
The purpose of this invention is to provide a kind of mortar that can use stone flour in a large number.
A kind of stone powder mortar, it is characterized in that the stone flour particle diameter mixes aggregate such as mortar about 20% at 0.08-5mm for sand, improved the grating of fine aggregate, aggregate chips surface irregularity porous, improved interface bonding with cement stone, the pulverized particles of trying one's best during making diameter makes it have activity below 1.5mm, quickens C in the cement
3The aquation of S and and C

4The AF reaction generates some crystallization hydrated products.
Such stone powder mortar is mixed stone flour and is had favorable economic benefit in concrete and building mortar, also have certain environmental benefit and social benefit simultaneously, and thicker stone flour also is that a kind of ideal is for the sand material.
Embodiment
The 17th Session of the General Assembly reporting requirement of party " exploitation and promote to save, substitute, advanced and applicable technology that recycle and improvement are polluted; development clean energy and renewable energy source; protection soil and water resources, builds scientific and reasonable Energy resources and utilizes system, raising Energy resources utilising efficiency." at Mineral resources; this just requires us will develop and promote mineral resources comprehensive utilization technology and solid waste comprehensive utilization technique energetically; reach economic construction and population, resource and harmonious development; can develop the economy; the natural resources and enviroment that can protect the mankind to depend on for existence again, and the mankind can continuously be developed.
For a long time, often the stone flour of particle diameter below 0.08mm is used as a kind of nonactive blended material and is used for manufacture of cement, therefore the volume of regulation stone flour in ordinary Portland cement is limited in below 8% in GB175-2008 " general purpose portland cement ".In fact, stone flour not exclusively is a kind of inactive inert material, except that its micro-aggregate filling effect, the cement early hydration is also had promoter action, and forms new aquation phase.On the other hand, the stone flour of particle diameter more than 0.08mm being used as gathering materials of concrete and building mortar uses.From this point, utilize the heavy burden of stone flour will drop on it efficiently, in a large number as the adulterant of concrete and building mortar or the aspect that gathers materials.Therefore, as adulterant with gather materials and be applied to the preparation of building mortar, and carry out industrialization, have important theoretical, put into practice, technology, environment and economic implications by the experimental study stone flour.
In Japan, stone flour has begun to be widely used in high-flowing concrete and high performance jetting concrete.From year March in April, 1996 to 1998, Japanese concrete research institute (JCI) specify the arrangement of the stone flour utilisation technology council to formulate the quality standard of stone flour and be applied to concrete and building mortar in Methods Instruction.In 1992, among the European standard ENV197, the stone flour of compound ordinary Portland cement replaced ratio and has fixed on 6%-10% and 21%-35% (massfraction).
And domestic rest on conceptual phase, also do not have the appearance of this class standard.The Li Yue of Beijing University of Technology etc. discovers that stone flour has a good application prospect in cement concrete as a kind of new modified material, particularly be used the stone flour compound activator, can stably produce stone powder mixing quantity with the grog of ultimate compression strength 52.5MPa and be 30% 42.5MPa cement.And an amount of stone flour can significantly improve the early strength and the slump of cement concrete, and reduce the slump through the time lose, the stone flour compound activator also has good enhancement for big volume concrete of stone powder, the C of wherein single carbon type

3The stable hydrated product that the A reaction produces is to promote that cement concrete is early strong and improve one of reason of shrinking.
The Yang De of Logistics Engineering College of PLA is refined to discover that mixing stone flour all improves significantly to every performance of concrete and building mortar, and the reason that stone flour can improve concrete and mortar performance mainly is the grating that stone flour has improved fine aggregate; Aggregate chips surface irregularity porous has been improved the interface bonding with cement stone; Thinner stone flour also has certain activity, can quicken C in the cement

4The AF reaction generates some crystallization hydrated products.Therefore, mix stone flour and have favorable economic benefit in concrete and building mortar, also have certain environmental benefit and social benefit simultaneously, thicker stone flour also is that a kind of ideal is for the sand material.
The Song Ying of China Building Materials Academy discovers that stone flour is better for the every performance index of sand concrete, its gain in strength rule and river sand concrete are basic identical, so stone flour can be undertaken by the river sand concrete mixing proportion design method for the proportioning design of sand concrete, but will suitably increase water consumption.
