Embodiment 1
[0028] A kind of grout for grouting concrete formwork blocks, including cement, fine aggregate and mineral admixture, the fine aggregate is uniformly mixed with cinder and stone chips in any ratio, and the mineral admixture is composed of fly ash and slag The micropowder is uniformly mixed in any ratio, and the mass parts of each component are as follows:
[0029] Component Mass parts (%)
[0030] cement 10
[0031] Cinder 5
[0032] Stone Chips 45
[0033] fly ash 4
[0034] Slag fine powder 36
[0035] Among them, the particle size of coal slag in the fine aggregate is not greater than 15mm; the fly ash in the mineral admixture is grade II fly ash, that is, the fineness of fly ash is between 12 and 25; the cement is selected from "GB 175- Ordinary Portland cement with a strength grade of 42.5 as defined in 1999 Portland Cement, Ordinary Portland Cement, that is, the compressive strength and flexural strength of each age of cement are: the 3-day compressive strength is n...
