Abstract
The invention belongs to the change of cement additive.
The main points of invention are to make cement with active very low copper slag as mixing material.According to whether making silicate copper slag cement and no grog copper slag cement with cement clinker.Both enlarge the scope of cement additive, handled the waste residue of copper smelting plant again.
Description
The invention belongs to the change of cement additive.
When grinding cement, except that the gypsum of admixture 3～5%,, regulate cement mark for improving cement performance, be called mixing material and be added to the artificial or natural mineral material that goes in the cement.
The Portland clinker not cement made of admixture mixing material is a silicate cement, cement for the admixture mixing material, difference according to institute's admixture mixing material kind, quantity can be divided into ordinary Portland cement, slag cement, trass cement, pulverized fuel ash cement.
Without cement clinker, only mixing material is cooperated by suitable proportion, mixing is levigate makes clinker-free cement.Its kind has, lime pozzolanic cement, lime slag cement, gypsum slag cement, red-mud sulphated cement and steel slag cement, iron-tion slag cement.
Used slag in the mixing material all is meant granulated blast-furnace slag (GB-77, GB1344-77 regulation).The slag melt that granulated blast-furnace slag generates when being the blast-furnace smelting pig iron gets through the quenching granulating (GB203-78 regulation).Various places slag composition difference.In general, silicon, calcium, aluminum oxide account for more than 80% in the slag, ferriferous oxide seldom adopts alkaline coefficient Mo, reactivity coefficient Ma, quality coefficient Ko to weigh scoriaceous activity, the blast-furnace slag composition of some Steel Plant of China and Mo, Ma, Ko value such as following table usually
Blast-furnace slag chemical ingredients (%)
Granulated blast-furnace slag is the cement active mixed material of present widespread usage, and its quantity has not satisfied the demand of Cement industry development.
When copper ashes was copper smelting by pyrometallurgy production blister copper, the slag melt of generation got through the quenching granulating.Its main component is as follows
Composition SiO
2Al
2O
3CaO MgO FeO
Content % 30～35 2～4 8～10 2～4 33～35
Copper ashes composition and blast-furnace slag composition differ greatly.Calcium in the copper ashes, aluminum oxide content are low, and ferriferous oxide content height is weighed with Mo, Ma, the Ko value of granulated blast-furnace slag, copper ashes active much lower.Therefore, copper ashes does not obtain utilizing basically.Copper is smelted one ton of copper of every production at present, approximately produces five tons of copper ashes, and there is nearly 2,000,000 tons of copper ashes discharging in the whole nation every year, and a large amount of copper ashes ties up farmland, mountain forest, and causes environmental pollution.
The objective of the invention is to, enlarge the scope of slag cement mixing material, waste residues such as comprehensive utilization copper ashes, production is suitable for the working cement of common engineering.
Draw through the test of the different proportionings of multiple industrial residue and to add lime, liquid slag (a kind of slag of the fuel-burning power plant similar), can excite the activity of copper ashes, thereby can use copper slag manufactured copper slag cement to the flyash composition.
The production method of copper slag cement is to cooperate with certain proportion with copper ashes, lime, liquid slag, gypsum with Portland clinker, through stirring and evenly mixing, is ground to cement requirement fineness, makes the silicate copper slag cement.Then make no grog copper slag cement without cement clinker.
The better proportioning of material is that copper ashes weight and liquid slag weight ratio are 1: 0.8～1.2, and the copper ashes amount can add to 40% of cement total amount, and cement clinker consumption increases, and can reduce lime consumption.
Embodiment one cement clinker (525) was with 20% o'clock (weight percent)
Copper ashes 30～35% liquid slag 25～30%
Lime 10～15% gypsum 3～5%
Ultimate compression strength 350～330kg/Cm
2
Folding strength 69～72kg/Cm
2
Intensity enhancement rate was 122% in 28 days to 90 days
Embodiment two is during without grog
Copper ashes 40% liquid slag 40%
Lime 15% gypsum 5%
The copper slag cement technical feature meets national standard, compares with portland blast-furnace slag cement, and its hydration heat is low, and later strength enhancement rate is big, and anti-freezing property, folding strength all are higher than with the label cement standard.Copper slag cement is fit to common engineering construction, in the time of can avoiding cement of high index preparation low grade mortar, concrete, because the inconvenience that the workability difference is brought to use.Produce cement with copper ashes, enlarged the scope of cement additive, handled the waste residue of copper smelting plant.Because the copper slag cement production cost is low, ten thousand tons of copper slag cements of every production just can be benefited 400,000 yuan.
Claims (3)
