Description
Technical field
The invention discloses a kind of construction refuse regenerated high-activity mineral blending material and its preparations, specially construction material skill
Art field.
Background technique
For the intensity and durability for improving concrete in work progress, it will usually be added in cement or concrete some super
Thin mineral admixture, currently, using effect is good and application more generally silicon ash.But silicon ash exists as active blend to be permitted
More defects specifically include that 1) silicon ash source is single, and resource is limited, it is difficult to meet market large-scale use demand；2) silicon ash cost
Higher, about 2000~3000 yuan/ton of market price, economy is poor.
With speeding for Chinese Urbanization's construction speed, the building generated in urban renewal, transformation, maintenance, demolishing process is useless
Gurry is increasing.These building castoffs cause serious adverse effect to The Surroundings in Cities protection work, make city
Face severe " garbage-surrounded city " problem.Requirement of the road structure to the strength of materials is lower, and structure is not related to safety problem.More
It is important that it is huge to the demand of regenerated aggregate in road engineering, therefore building castoff is subjected to regeneration and is applied to road work
It is considered as a kind of energy-saving and environment-friendly technology in journey, can effectively reduces the primary exploitation gathered materials, while can solve and building again
Build the handling problems of waste.
Summary of the invention
The purpose of the present invention is to provide a kind of construction refuse regenerated high-activity mineral blending material and its preparations, on solving
State the problem of proposing in background technique.
To achieve the above object, the invention provides the following technical scheme: a kind of construction refuse regenerated high-activity mineral blending material, institute
It states the construction refuse regenerated high-activity mineral blending material to be made of the raw material of following weight parts: cement: 80~90 parts；Fine aggregate:
160~180 parts；Recycled aggregate: 320~360 parts；Rice hull ash: 10~20 parts.
Preferably, the fine aggregate is the natural sand of 0.63~1.25mm partial size.
Preferably, the partial size of the recycled aggregate is 9.5~19mm.
Preferably, the construction refuse regenerated high-activity mineral blending material includes water-reducing agent.
Preferably, the rice hull ash uses low-temperature rice husk ash.
A kind of preparation method of construction refuse regenerated high-activity mineral blending material, method includes the following steps:
Step 1: the processing of recycled aggregate: discarded concrete component is crushed after rejecting the impurity such as plastics, stationery and sawdust,
It is sieved respectively with the square hole stone screen of 9.50mm, 16.0mm and 19.00mm after broken, obtains 9.5~19mm continuous grading again
Raw aggregate；
Step 2: the processing of rice hull ash: rice husk low temperature ashing furnace burning-off organic matter remains lower inorganic matter silica ashes etc.,
Again through grinding and sieving, rice hull ash is obtained；
Step 3: cement and step 2 is added in the rice hull ash in recycled aggregate, cement and the step 2 in fine aggregate, step 1
In rice hull ash parts by weight 60% water stirring, obtain high-activity mineral blending material.
Compared with prior art, the beneficial effects of the present invention are:
1) present invention uses the rice hull ash of low temperature grinding, the silica containing high-content in low-temperature rice husk ash, thus by low
Warm rice hull ash replaces silicon ash to prepare concrete, can effectively meet the extensive demand in market, production cost is effectively reduced；
2) present invention uses recycled aggregate, solves the handling problems of the primary exploitation gathered materials and building castoff.
