Embodiment
Embodiment with concrete is further explained to explanation to new concrete of the present invention and preparation method below, but this is explained and is not formed the improper restriction to technical solution of the present invention.
The present invention is directed to new concrete selects trolamine modified polystyrene particle to make concrete segment proportioning in Table 1:
Table 1
The anti-folding of granules of polystyrene concrete segment, compressive strength test the results are shown in Table 2:
Table 2
As shown in table 1, by volume, volume fraction is 10%, 15% to granules of polystyrene volume.For to make the cement amount of masterbatch be cement consumption 1/3rd, be approximately 2.5 times of EPS quality.Properties-correcting agent adopts trolamine, and wherein trolamine consumption is 6% of EPS granular mass.
Granules of polystyrene volume adopts three kinds of method of modifying to obtain cement-based material and 7 days, 28 days folding strength tables of blank sample while being 10%, 15%.Three kinds of method of modifying are respectively:
1) adopt and not make shell method and comprise: successively granules of polystyrene, properties-correcting agent, gelling material, Sha Heshui are poured in agitator kettle and stirred, stir.
2) adopt make shell not ageing method comprise: spraying modified dose of granules of polystyrene surface uniform to particle surface wetting evenly after, a certain amount of cement is evenly sprinkling upon to particle surface, particle is wrapped up by cement completely, stir and obtain masterbatch.Then add residue gelling material, sand, water, then stir.
3) adopt and to make shell ageing method and comprise: spraying modified dose of granules of polystyrene surface uniform to particle surface wetting evenly after, a certain amount of cement is evenly sprinkling upon to particle surface, particle is wrapped up by cement completely, stir and obtain masterbatch.Masterbatch was sealed to ageing after 24 hours, add remaining gelling material, sand and water mix and blend.Hence one can see that:
No matter granules of polystyrene volume is 10% or 15%, after the surface modification through properties-correcting agent trolamine, do not make shell (directly dispersing and mixing), make not ageing of shell, make three kinds of method of modifying of shell ageing and all can effectively improve the folding strength of granules of polystyrene lightweight concrete building block.But method of modifying is different, it is also different that the folding strength of building block improves degree.
No matter granules of polystyrene volume is 10% or 15%, the folding strength of not making shell method of modifying (2#, 6#) and not ageing method of modifying (3#, 7#) is close, and apparently higher than blank sample (1#, 5#) with make the folding strength of two groups of samples of shell ageing method of modifying (4#, 8#).When wherein granules of polystyrene volume is 15%, 28 days folding strengths of not ageing method of modifying (7#) sample are the highest, than blank sample (5#), improve 32.3%.
