Abstract
The invention provides an application of high-content pebbles in concrete. The concrete comprises raw materials in parts by weight as follows: 80-110 parts of cement, 40-70 parts of coal powder ash, 85-95 parts of pebbles, 40-50 parts of fine sand and 12-16 parts of a foaming agent, wherein a ratio of water, the cement, the coal powder ash, the pebbles, the fine sand and the foaming agent is kept to be 0.5-0.65, the cement, the sand, ground fine mineral powder, the coal powder ash and a water reducing agent are put in a large mandatory type stirrer and stirred for 30 min, the high-content pebbles are added for stirring, and the stirring time is not shorter than 120 min. According to the application of the high-content pebbles in the concrete, a large quantity of sediments in a river channel is cleaned, the river channel becomes clear and smooth, large quantities of manpower and material resources for flood control are reduced, unnegligible contribution to the flood control work is provided, and great social and economic benefits can be produced.
Description
Technical field
The present invention relates to building material technical field, particularly relate to the application of a kind of large dosage cobble in concrete.
Background technology
Concrete is that in modern civil construction project, consumption is maximum, a kind of material of construction that purposes is the widest, and play the irreplaceable function and efficacy of other material, its medium stone is the important component part in concrete.Along with the quickening of Process of Urbanization Construction process paces, the develop rapidly of building trade, increases day by day to the demand of building stone, but due to rock, cobble geographical resource skewness, causes the shortage of some areas rubble, cobble.Because mountain stone overexploitation causes great destruction to environment, mining blasting generation security incident also occurs often.In rivers, Gobi desert exploits sand and the cobble that can be used in concrete leaves over the dead meals such as lower undesirable bulk cobble, be thrown in river bed water everywhere and Gobi desert ground, define a underwater bank submerged reef everywhere, cause and hidden danger to rivers navigation channel, even block navigation channel, waste the limited and natural resources of preciousness simultaneously.Country and various places local government, all take a large amount of manpower and financial resources every year to dredge cleaning river course.As Middle And Upper Reaches of The Yangtze River, the upper reaches of the Yellow River, and each many Province of mountain regions inland river etc., all have in various degree owing to exploiting the dead meal residual packing after channel sand, cobble in riverbed under water, how both can clear up the bulk deposition thing in river course, allow river course become unblocked, can reduce again a large amount of man power and material's flood control investment, having made very important contribution for flood control is that we need the difficult problem of solution badly.
Summary of the invention
In order to overcome the problem of prior art, the invention provides the application of a kind of large dosage cobble in concrete, it has not only cleared up the bulk deposition thing in river course, river course is allowed to become unblocked, decrease a large amount of man power and material's flood control investment, for very important contribution has been made in flood control, and can have a tremendous social and economic benefits.
Technical scheme of the present invention is: provide a kind of large dosage cobble, and with parts by weight, described raw material weight ratio is:
The ratio of described water and cement, flyash, cobble, fine sand, pore forming material remains on 0.5-0.65.
The preparation method of described large dosage cobble, fully mixes cement, flyash, cobble, fine sand, pore forming material, adds water and stir after mixing, until the ratio of water and cement, flyash, cobble, fine sand, pore forming material remains between 0.5-0.65.
Describedly put in large-scale pressure type stirrer by cement, sand, ground blast furnace slag, flyash, water reducer, stir 30 minutes, then add large dosage cobble and stir, churning time is not less than 120 minutes.
Described cobble adopts the Ji Xing that borders on the sea to produce the artificial crushed gravel of reaction type, the artificial rubble of Jiangjiang and the natural pebble that borders on the sea.
The invention has the beneficial effects as follows: both improve concrete every physical index, improve pump concrete and easily shrink and occur characteristic of crack, improve resistance to cleavage, achieve again good economy and social benefit simultaneously.
Embodiment
Large dosage cobble, with parts by weight, described raw material weight ratio is:
The ratio of described water and cement, flyash, cobble, fine sand, pore forming material remains on 0.5-0.65.
The preparation method of described large dosage cobble, fully mixes cement, flyash, cobble, fine sand, pore forming material, adds water and stir after mixing, until the ratio of water and cement, flyash, cobble, fine sand, pore forming material remains between 0.5-0.65.
Describedly put in large-scale pressure type stirrer by cement, sand, ground blast furnace slag, flyash, water reducer, stir 30 minutes, then add large dosage cobble and stir, churning time is not less than 120 minutes.
Described cobble adopts the Ji Xing that borders on the sea to produce the artificial crushed gravel of reaction type, the artificial rubble of Jiangjiang and the natural pebble that borders on the sea.
The present invention has not only cleared up the bulk deposition thing in river course, allows river course become unblocked, decreases a large amount of man power and material's flood control investment, for very important contribution has been made in flood control, and can have a tremendous social and economic benefits.
The above is embodiments of the invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.All any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc. all should be contained within right of the present invention.
