The preparation method of described a kind of controlled injecting paste material of rapid hardening time:
Proportionally weigh the water of corresponding weight, common 325 grades of silicate cements or ordinary Portland cement, 42.5 grades of aluminosulfate cements, the ethylene-vinyl acetate copolymer emulsion of 99.9wt%, admixture, hardening accelerator, retardant, put into stirrer and be stirred to evenly, make slurries; Made slurries are put into mould with moulding, maintenance.
The invention provides a kind of controlled injecting paste material of rapid hardening time, its slurry degree, initial set and final setting time, 28 days folding strengths, ultimate compression strength character are as described below:
(1) degree of mobilization.For a kind of controlled injecting paste material of rapid hardening time of the present invention, according to GB50119-2003 appendix A, carry out the test of standard flow degree, recording this material degree of mobilization is 26.8cm, the property noted is good.
(2) initial set, final setting time.For a kind of controlled injecting paste material of rapid hardening time of the present invention, according to GB175-2007 general purpose portland cement standard, use standard consistency method to test consumptive use of water normal consistence, initial set final setting time, obtained experimental result sees the following form.
With respect to the Portland cement character of code requirement, can guarantee, under the prerequisite of mortar depositing construction time, to have obtained effective shortening time of coagulation.
(3) resistance to compression, folding strength.For a kind of controlled injecting paste material of rapid hardening time of the present invention, according to GB/T17671-1999, prepare the standard specimen of 40 * 40 * 160mm, maintenance is successively carried out anti-folding, compressive strength test in 28 days afterwards, and obtained experimental result sees the following form.
As seen from the above table, novel material is compared common 32.5 grades of silicate cements and is only starched, and folding strength, ultimate compression strength have all obtained effective lifting.
(4) swelling property.For a kind of controlled injecting paste material of rapid hardening time of the present invention, the volume shrinking when estimating that slurries solidify, use with mould surveyed the volume of slurries and solidify after volume, can for referencely contrast:
Die quality: 6.220kg, quality after moulding: 6.610kg, can extrapolate slurries quality is 390g, slurry volume is 40 * 40 * 160mm
3; After condensing, solid masses is 372.3g, and after condensing, solid volume is 245mL.
As calculated: retraction volume is 245-40 * 40 * 160 * 10
-3=11cm
3,
From above, know: for m=390-372.3=17.7g answers vaporize water, retraction volume is 17.7cm to the quality of the vaporize water that condenses
3;
Hence one can see that test specimen expansion of solids volume v=17.7-11=6.7cm
3
Rate of expansion w=6.7/245 * 100%=2.735%.
From above 4, with respect to current material, material of the present invention has rapid coagulation, and early strength is higher, and later strength also meets the demands, and has certain expansile excellent characteristics.
Embodiment
Below in conjunction with embodiment, be intended to further illustrate the present invention, and unrestricted the present invention.
