Abstract

A gypsum-slag cement, belonging to the cement containing calcium sulfate, activator, is prepared from slag, gypsum, alkaline trigger, rock as filler and waste dreg as filler in weight ratio of (40-80) : (4-20) : (1-20) : (1-40) : (40-50) through pretreating, baking, crushing, grinding and homogenization. Its advantages include low cost, rich raw materials, high early strength and preventing environmental pollution.

Description

The novel gypsum slag cement prescription and the preparation method that contain the waste residue casting resin
The invention belongs to sulfur acid calcium activator slag cement technical field.
Gypsum slag cement be a kind of be main raw material with the granulated blast-furnace slag, be the sulphate activation agent with the gypsum and be the few grog or the clinker-free cement of alkali-activator with grog or lime, be specially adapted to water works.Its advantage be unburned, technology is simple, energy-conservation, and can make full use of industrial residue, weak point is that freely supply falls short of demand in starting material slag source, sclerosis is slow, early strength is not high, the wheat face easily plays sand, must strict maintenance during use etc.The Chinese patent communique discloses a kind of number of patent application and has been 93108773.2 and is called " quick setting high strength low heat-generating gypsum slag cement ", and it is formed to divide and comprises slag, gypsum, lime and grog, but is not suitable for masonry and thin-walled building, and cost is higher.
The object of the present invention is to provide a kind of prescription and preparation method who contains the gypsum slag cement of waste residue casting resin, the high and low cost of early strength.
The object of the present invention is achieved like this, a kind of novel gypsum slag cement prescription and preparation method who contains the waste residue casting resin, and its moiety comprises slag, gypsum, alkali-activator, rock fill material and waste residue casting resin.
Slag is blast-furnace slag, as the base-material of cement;
Gypsum is as the sulphate activation agent;
Alkali-activator can use lime also can use cement clinker;
The rock fill material can select one for use to several from following material; Shale, coal gangue, float stone, barite and Wingdale;
The waste residue casting resin, can from following material, select for use one to several: flyash, slag, Metal smelting slag, chemical industry tailing phosphorus-containing waste slag, relieving haperacidity waste residue, through the active waste residue of the domestic refuse of calcination processing.
The weight proportion of each moiety is as follows:
Slag: gypsum: alkali-activator: rock fill material: waste residue casting resin
＝(40～80)∶(4～20)∶(1～20)∶(1～40)∶(40～50)
Its preparation method is as follows:
A. pre-treatment: at 750 ℃～1100 ℃ temperature lower calcinations, after-flame becomes the active waste residue of domestic refuse with domestic refuse;
B. oven dry: moisture in the moiety greater than 2% material, is sent into dryer respectively, under 400 ℃～1100 ℃ temperature, dry, make the average moisture of material be controlled to be 1～2%, to satisfy into the mill requirement;
C. broken: as size to be sent into crusher respectively greater than the material of 1.5cm, be broken for the fragment of size less than 1.5cm;
D. prepare burden: by following weight ratio batching
Slag: gypsum: alkali-activator: rock fill material: waste residue casting resin
＝(40～80)∶(4～20)∶(1～20)∶(1～40)∶(40～50)；
E. grind: it is levigate that the material for preparing is sent into shredder, makes the specific surface area of mixture reach 3000～9000cm 2/ g; Because gypsum and lime are softer, slimeball, sticking mill easily, can be earlier with unclassified stores levigate be 2500～3000cm 2/ g adds gypsum and lime again and mixes levigate;
F. homogenizing: the levigated mixture is sent into homogenizing in the homogenization installation, make finished product.
Advantage of the present invention is owing to add rock fill material and waste residue casting resin; can significantly reduce costs; and solved the slag insufficient problem of originating; product early strength height, surface have been difficult for husky; because a large amount of industrial residue and domestic refuses used are for preventing and remedying pollution, protect environment that significant effect is arranged.
Each moiety formulation weight of the present invention is as follows than embodiment:
Embodiment one:
Slag: gypsum: grog: coal gangue: flyash: the active waste residue of domestic refuse
＝40∶20∶15∶25∶10∶30
Embodiment two
Slag: gypsum: lime: shale: Wingdale: flyash: chemical industry tailing phosphorus-containing waste slag
＝50∶15∶1∶5∶13∶20∶21
Embodiment three
Slag: gypsum: lime: Wingdale: relieving haperacidity waste residue: the active waste residue of domestic refuse
＝50∶15∶1∶5∶13∶20∶21
