Abstract
The invention discloses a kind of all steel dreg concrete, it is a coarse aggregate with the slag piece, is fine aggregate with the steel-making slag powder, adds water and cement again, processes by quantitative cooperation.
Cost of the present invention is low, intensity is high, obvious social benefit, and it is turned waste into wealth, and turns harm into good, and helps social environment protection and comprehensive utilization.
The present invention is applicable to each field of corresponding construction work that needs in the national economy with concrete material.
Description
The invention belongs to material of construction, more particularly, belong to a kind of build concrete.
Before the present invention made, used concrete in the existing building engineering all was to make fine aggregate with sand traditionally, does coarse aggregate with stone, utilizes water and cement to process by quantitative cooperation again.But come because building stones will be processed, transport from the stone quarry, sand will ship from rich sand districts such as river shoals, and its cost is high than slag all.And because stone, these places of origin of raw materials of sand are different, impurity is many in the natural matter, can have a negative impact to concrete quality, the natural particle diameter of sand grains is difficult for reaching codes and standards simultaneously, also will manually join sand, otherwise will make concrete voidage increase strength degradation.
The present invention is exactly the above-mentioned shortcoming of gathering materials at existing concrete, the consumption of the composition consumption of used thick, the fine aggregate of concrete, cement, water etc. is reformed, thereby invented concrete made of slag aggregate.
Main points of the present invention are: utilize the efflorescence store up more than year back particle diameter that expands to expand the back particle diameter at 0 millimeter-8 millimeters at 8 millimeters-80 millimeters slag piece for coarse aggregate and the efflorescence of storing up more than a year, and be fine aggregate through the mine tailing steel-making slag powder of dry type magnetic separation, replace sand, stone in the conventional concrete to gather materials, and the consumption of said slag piece in concrete is 1000 kilograms/meter
3-1500 kilograms/meter
3, the consumption of said steel-making slag powder in concrete is 500 kilograms/meter
3-1000 kilograms/meter
3, simultaneously, also include in every cubic meter of concrete: ordinary Portland cement and consumption that consumption is 100 kilograms-500 kilograms are the water of 100-300 kilogram.Mainly utilize above-mentioned materials, by traditional preparation concrete making technology, different numerical value according to each amount ranges of above-mentioned slag piece coarse aggregate, steel-making slag powder fine aggregate, water, cement cooperate processing respectively, just can be made into all steel dreg concrete (seeing the most preferred embodiment subordinate list) of different labels.
For satisfy workability of concrete can requirement, reduce porosity, in coarse aggregate, should guarantee that particle diameter is 1 at the ratio of 8 millimeters-20 millimeters little slag piece gross weight and whole coarse aggregate gross weights: 2-1: 3.
Slag is the artificial stone who comes out through 1600 ℃ of high melts, impurity is few, its composition mainly is that Dicalcium Phosphate (Feed Grade), tricalcium silicate, calcium ferrite, iron calcium aluminate, RO equate, major part is a silicate family in these components, they and cement slurry have natural avidity, natural grading in the ground-slag is fit to code requirement, thereby they can be with cement slurry molten and play the effect of increase cement slurry together.
Slag piece and slag piece are used as concrete aggregate, can prepare the concrete of the different labels below No. 400, can build the concrete road surface, can beat concrete foundation, can manufacture concrete product or the like.Using under the equivalent cement proportion condition, can make the concrete made of slag aggregate label improve 20-50%, can save about cement 20-30%, in addition like this than normal concrete label, the price of slag as aggregate only is equivalent to sandstone 1/3 of the price of gathering materials, and this just makes cost descend about 40%.Therefore, the cost of all steel dreg concrete is low, intensity height, obvious social benefit.
And about 100,000,000 tons of slag is stored up in the whole nation at present, about 8,000,000 tons of annual also constantly newly-increased slag.Remove outside the iron and steel scrap of recycling 3-7% wherein and a large amount of goods and materials such as refractory materials, remaining nearly 0.55 hundred million ton of slag piece, 0.35 hundred million tons of steel-making slag powder (wherein can also magnetic separation reclaiming grade) 0.13 hundred million ton of the rich ore powder of 55-57%, can produce 0.356 billion cubic meter concrete, save 40 yuan of calculating, 3.9 hundred million yuan of create beneficial results by every cubic metre.Overall economic efficiency is 18.15 hundred million yuan.And, also can vacate about more than 10,000 mu of soils.This just can turn waste into wealth, and turns harm into good, and helps the social environment protection, removes and pollute and comprehensive utilization, saves a large amount of sand, stone raw materials and will go back to into the soil of ten thousand mu of preciousnesses to the Nature can for again country simultaneously.
The present invention is applicable to each field of corresponding construction work that needs in the national economy with concrete material.
Most preferred embodiment of the present invention:
By No. 300 concrete prescriptions in the concrete made of slag aggregate proportioning table (seeing attached list), with 1.14 kilograms of No. 425 normal silicate slag cement, 3 kilograms of the steel-making slag powder that particle diameter is 0 millimeter-8 millimeters, 4.85 kilograms of the slag pieces of particle diameter 8 millimeters-30 millimeters (length of side is that 100 millimeters test block requires the coarse aggregate grain size maximum to be no more than 30 millimeters) (wherein, the slag piece that particle diameter is 8 millimeters-20 millimeters should have 1.6 kilograms), and 0.75 kilogram of water, wherein used slag piece and slag piece and steel-making slag powder are the old slag of storing up more than a year, process according to the concrete technology of traditional preparation, and by " specifications of engineering construction compilation 15 " (China Construction Industry Press, August first in 1985 plate, standard book number: 15040-4784 ┲ Xiao Ao ㄖ herds existing persimmon and surveys sunlight and add the very small swish Ping of wooden tablets or slips for writing otter barium tomb Suo ㄖ and shoot a glance at moisture in the soil key spinulose tree fern
Should cover behind the test block forming, in case water evaporates, be 20 ± 5 ℃ indoor leaving standstill 24 hours in room temperature, numbers form removal then, was placed on 20 ± 3 ℃ of temperature, relative humidity and is in the standard curing room more than 90% maintenance 28 days, then does compression tests.In order to examine the stability of test block, we with test block 9.80665 * 10
