Dispersio resistentia est magna technica index ut metiretur qualis est anti - dispersant.Hydroxypropyl methyl CelluloseEst aquam, solutum polymer compositis, etiam ut aqua-solutum resinae vel aqua-solutum polymer. Auget consistency mixturam augendae viscositas mixtionis. Est quaedam hydrophilic polymer materiam, quod potest dissolvi aquam et formare solution vel dispersum liquor. Experimenta ostendere quod cum moles Naphthalene ratio superplasticizer augetur, additionem superplasticizer mos redigendum dispersionem resistentia recenti cæmentarii. This is because the naphthalene series high efficient water reducing agent belongs to the surface active agent, when the water reducing agent added to the mortar, the water reducing agent in cement particle surface oriented surface of cement particles with the same charge, the electric repulsion flocculation structure of cement particles formed by dividing, wrap in the structure of water release, will cause the loss of part of the cement. Simul invenitur quod augmentum HPMC contentus, anti dispersionem nova cæmento melius et melior.
Fortitudo characteristics de concreto:
HPMC Underwater non-dispertimus concretum admixtum esse applicari in ponte fundamenta ipsum de expressway et consilio vires gradu C25. Post basic test, caementa dosis est 400kg, compositis mixta silica furum 25kg / m3,HPMCoptimum dosage is 0.6% of cement dosage, water cement ratio is 0.42, sand rate is 40%, naphthalene high efficiency water reducing agent yield is 8% of cement dosage, the concrete specimen in air 28d, the average strength is 42.6MPa, The average strength of the underwater poured concrete with a falling height of 60mm in water is 36.4mpa for 28 days, and the strength ratio of the concrete Formatae in aquam et concretum formatae in aere est 84,8%, showing a significant effectus.
I. Praeterea de HPMC habet obvious retardare effectus in cæmento mixtisque. Cum incremento HPMC dosis, occasum tempus mortario est longum differentur successive. Sub eadem conditione HPMC dosis, occasum tempus underwater cæmento est quam aere. Hoc pluma est utile ad underwater concreto elit.
II, mixta cum hydroxypropyl methyl cellulosose de nova cæmento est bonum cohaesionis, paene non sanguinem phaenomenon.
III, HPMC Dosis et cæmento aquae postulant primum minuatur et auctus significantly.
IV. Incorporacionem aquarum reducer improves problema augendae aquam demanda ad cæmento, sed oportet recte regi, aliter autem aliquando redigendum underwater dispersionem resistentia recenti cemento.
V. Modicum differentia in structuram inter HPMC mixta caementa rete slurry specimina et blank specimens et parum differentia in structuram et pacto aqua infudit cement specimens et aer infudit caementum slurry specimens. Et 28d underwater CUMATIUM specimen est leviter solutam. Pelagus est quod etiam HPMC valde reducit damnum et dispersionem cemento aqua infundens, sed etiam reduces gradum cementum compaction. In project, sub conditione cursus underwater non-dispersionem effectus, in miscentes moles HPMC reducitur quatenus fieri potest.
VI, addereHPMCUnderwater non disperse concretum admixtionis, control moles boni fortitudinem, in gubernator project ostendit quod virtus ratio formatam concretum in aqua et formatam in aere est 84.8%, effectus est magis significant.
