Abstract
The invention belongs to the technical field of building materials and in particular relates to masonry mortar prepared from tailings. The masonry mortar is characterized by comprising the following components in part by weight: 100 to 245 parts of portland cement, 1,270 parts of tailings, 234 to 56 parts of lime putty, 1 to 1.36 parts of water reducer, and 277 parts of water. The tailings has the granularity of 0.15-0.3 millimeters; and in process flows of gravity separation and magnetic separation, the tailings are obtained by stages through sieving equipment so as to prevent harmful substances from being mixed and avoid a condition that the mortar has low fluidity and cannot be constructed due to too fine tailings. The production cost is about 20 yuan per cubic meter, about 60 yuan can be saved in each cubic meter, and the benefit in each year is about 0.18 billion yuan. In addition, the tailings replace river sand, so that the emission of mine tailings can be reduced, the service life of a tailing pond is prolonged, the damage of exploitation of the river sand to natural riverways is reduced, and the aims of occupying less rural land and protecting environment are fulfilled finally.
Description
Technical field
The invention belongs to building material technical field, relate in particular to a kind of masonry mortar of making of mine tailing.
Background technology
Masonry mortar is an indispensable raw material in the structure material, and wherein the ratio of contained river sand is about about 70%, and China's river sand resource is at full stretch at present, and sand exploitation in river is very serious to the destruction of natural river course.With the area, Anshan is example, the annual a large amount of river sand of consumption that needs of urban construction, only chutable concrete is annual just needs about sand 150 ten thousand steres of river, also have river sand such as other concrete, motar to consume, conservative estimation river, whole urban district sand consumes between 200～300 ten thousand steres, therefore, be badly in need of a kind of equivalent material, destroy with the exploitation that alleviates natural river sand with to the river course.And the mine tailing that discharge in the dressing-works is a kind of good river sand substitute.The mine tailing in dressing-works all adopts pipe-line transportation to arrive the stacking of mine tailing storehouse at present, and a large amount of tailings piles are placed in the mine tailing storehouse, not only taken a large amount of rural holding, and surrounding enviroment are caused severe contamination.Therefore the comprehensive utilizating research of mine tailing is that market outlook are arranged very much with the alternative river of mine tailing sand making masonry mortar especially.
Summary of the invention
The purpose of this invention is to provide a kind of flowability and good endurance, can suppress and reduce the masonry mortar of making of mine tailing of the volumetric shrinkage that produces in the cement stone process of setting effectively.
The objective of the invention is to realize by following technical proposals:
The masonry mortar of making of mine tailing of the present invention is characterized in that producing the usefulness that satisfies M2.5-M10
The weight part proportioning that mine tailing is made masonry mortar is as follows:
Cement 100-245 part
1270 parts of mine tailings
Lime putty 234-56 part
Water reducer 1-3.6 part
277 parts in water,
Described mine tailing granularity is the 0.15-0.3 millimeter,
Described water reducer is chosen high efficiency water reducing agent.
The weight part proportioning of masonry mortar of the present invention can be selected by the different labels mortar, and for example the weight part proportioning of masonry mortar is as follows:
32.5# 245 parts of slag cement
1270 parts of mine tailings
56 parts of lime putties
3.6 parts of water reducers
277 parts in water.
Described mine tailing granularity is the 0.15-0.3 millimeter, in gravity treatment, magnetic separation process flow process, obtains by the screening plant classification, and what its purpose was to avoid objectionable constituent mixes that too the fine sand slurry is mobile little with the mine tailing granularity, can't construct.
Described water reducer is chosen the high efficiency water reducing agent of (3301CE) of the card production of west, Dalian.
The advantage of the masonry mortar of making of mine tailing of the present invention is:
1) because the present invention has adopted mine tailing to substitute river sand, not only solved the nervous problem of river sand resource,
But also realized mine tailing resource utilization industry scale development.
2),, stop concrete cracking as chemical shrinkage, dry shrinkage etc. because the reasonable preparation of mine tailing and cement, water reducer and water makes mine tailing can suppress and reduce the volumetric shrinkage that produces in the cement stone process of setting in mortar.Therefore masonry mortar flowability and the good endurance produced, and can suppress and reduce the volumetric shrinkage that produces in the cement stone process of setting effectively.Thereby realize mine tailing high added value recycling.
3) high efficiency water reducing agent can improve the flowability of masonry mortar, strengthens intensity, frost resistance and the impermeability of mortar.
4) substitute the discharging that river sand also can reduce mill tailings with mine tailing, prolong the mine tailing storehouse length of service, finally reach and take the rural holding less, reach the purpose of protection environment.
