Superplasticizer (I)

(一) et adaptabilityPolycarboxylate superplasticizer et caementa materiae:

In usu, quod inventa estPolycarboxylate superplasticizerAdaptability obvious diversis genera mineralibus admissuras aliter et aliquando etiam valde picky. Et adaptability inter cementum etPolycarboxylate superplasticizer erit affectus multis factores. Ut: Caementa components, specifica superficies area, alkali contentus, gypsi contentus et varietates omnes habent impulsum in adaptabilityPolycarboxylate superplasticizer.

Saturation punctumPolycarboxylate superplasticizerfor different cements is different, the water reduction rate is reduced, the slump loss of concrete is increased, the phenomenon of “bean curd residue” appears when the concrete lacks slurry, and the problems of bleeding, sedimentation and segregation, and difficulty in pumping , Sensitivo ad dosage, quod concretum non aperiri non potest, aut nimis dimisit. Exempli gratia, ad contentus estPolycarboxylate superplasticizer Nam cementum est 1.8% (solidum contentus de X%) ad obtinendum satis statu, cum b cement est pronus ad sanguinem.

In praesens, in terms of adaptabilityPolycarboxylate superplasticizer, Solutions sunt, ut sequitur:

(I) De praemissa ex concreto vires concretum, a adjusting arena rate, in magnitudine Ratio est gross aggregatum et augendae moles concretum ratio slurry;

(II) et mater liquor componitur aether lipids et dosis est appropriately augeri. Plerumque, id est suadetur quod a aethere et lipids V: V melior effectus, et dosis augeri auctus per 0.2%;

(III) appropriately addere vel mutare suum components, utere aere-entaraining agentibus ut SJ, DYGUS, spumam stabililerit ar, K12, auget proportionem Slump-retinendi agentibus, utuntur sodium gluconate, sugar, phosphate, atmp, citric acid Modified amulum et compositum retarders, utens solutum Cellulose, Xanthan gum, dextrin, modified soluble Thickener, aut addendo "sulphuris" vel "alkali" ad concretum potest melius;

(IV) Mutare ad Molecular structuram Polycarboxylic acidum et adjust quidam components in synthesis processus ad adjust suum adaptability.

Nam admissura, in potentia volant cinis manifesto maior quam de SLG pulveris. Generaliter loquendo, primum-gradu musca habet bonum adaptability, dum second- et tertia-gradu musca cinis est pronus ad incompatibilitatem, praesertim tertio gradu musca cinis. Cum cinis qualis est pauper, effectus augendae dosisPolycarboxylate superplasticizerIn tempore tamen non potest esse significantly melius. The main reason for this phenomenon is that the carbon content of secondary and tertiary fly ash with higher ignition loss is larger, and the adsorption capacity of carbon particles to admixtures is large, thereby reducing the adsorption of admixtures to cement, affecting the Concrete fluidity. Cum per gradus III volant cinis, auget contentus de Polycarboxylate aquam reducer magis quam L%, ut ad consequi aquam reductionem rate cum permixtione gradu unum musca cinis. In faciem hodie musca cinis cum complexu qualitas et diversis components, necesse est ad confirma qualitas potestate musca cinis et confirma test cum usura Polycarboxylate superplasticizer.
