| titleOfInvention | A kind of rear pouring concrete and preparation method thereof |
| abstract | The invention discloses a kind of rear pouring concrete and preparation method thereof, belong to build concrete field, for after solution pouring concrete exist curing cycles length, slow strength development, easy shrinkage cracking the problem of.It includes Portland cement 12%~17%, sulphate aluminium cement 1.7%~2.4%, aluminate cement 0.9%~1.2%, ground slag powder 1.7%~2.4%, intensity exciting agent 0.06%~0.07%, anhydrous gypsum 1.0%~1.5%, anhydrous sodium sulfate 0.2%~0.4%, polycarboxylate water-reducer 0.2%~0.3%, middle sand 17%~24%, 5 ~ 20mm rubbles 48%~51% and water 9%~10%.The rear pouring concrete has the advantages that the presetting period is short, strength development is fast, it is small not easy to crack to shrink. |
