Manufacturing

Foamed ihe a na mejupụtara a slurry nke ciment na ofufe uyi ma ọ bụ ájá na mmiri, ọ bụ ezie na ụfọdụ suppliers nwere ike ikwu dị ọcha ciment na mmiri na-asụ ụfụfụ gị n'ụlọnga maka nnọọ fechaa mixes. Nke a slurry bụ n'ihu weere na a sịntetik aerated ụfụfụ na a ihe Ịgwakọta osisi. Ụfụfụ na-kere iji a na-asụ ụfụfụ gị n'ụlọnga, weere na mmiri na ikuku si a generator.
