Otutu na ezi njupụta nke cement

Cement bụ isi akụrụngwa nke akọrọ mixes maka ewu ngwa, nke na-eji na-ewu ụlọ, na-ebikwasị ụzọ, mmejuputa iwu-mesikwuru ihe owuwu ma ọ bụ sere na decorating. Na-ewu omume cement njupụta (dị ka ibu na olu ruru) ekewa a nnukwu na ezi. Abụọ ndị a ji mara ndị dị iche iche na nnukwu njupụta tụrụ mgbe ihe bụ na a rụrụ ala. Ọ bụ 1100 - 1600 kg / cu. mita (1600 kg / cubic mita na densified ala).

Otutu njupụta nke ciment tụrụ site a pụrụ iche ngwaọrụ esịnede a foneelu na a gụsịrị akwụkwọ cylinder. The cement ngwakọta kapịrị arọ (2 n'arọ) na-wụsara n'ime foneelu, nke na-egbu oge na nnukwu inclusions. Mgbe nke ahụ gasịrị, ọ abatakwa cylinder, obravnivaetsya, wee ọnụ na cylinder ntukwasi. Nke ngụkọta nke ịdị arọ nke dapụtara ibu na-subtracted cylinder. Ọzọkwa, uka kewara ekewa site na olu na-enye ndị chọrọ ibu. The uru nke nnukwu njupụta na-eji mgbe itinye ihe igwekota mmiri maka nkwadebe nke ihe.

The ezi cement njupụta dị iche na nke ndị nnukwu na si cement ewepu niile ikuku mmiri. Nke a na-eduga onye na-abawanye na njupụta ruo 3000 - 3200 kg / cu. mita. The ụlọ na-eji maka ịgbakọ nkezi uru nke banyere 1300 kg / cu. mita. Ọ na-chere na ciment onye njupụta dịgasị dị otú ahụ a dịgasị iche iche, mma mma na ngwa agha, na nso ka nkezi njupụta uru.

The njupụta nke ciment na-adabere na ogo nke egweri mmiri, ọka n'elu na ihe onwunwe, na otú nkụ ngwakọta na silo. Ọzọkwa n'etiti ihe nwere ike kwuru nchekwa ọnọdụ - okpomọkụ, iru mmiri, na ndị ọzọ na e ji mara. The njupụta nke a ihe onwunwe dị ka simenti n'ihu na-ekpebi parameters dị ka ike na-eguzogide ndị penetration site mmiri (hydrophobic).

The njupụta nke ciment M400 na-adabere na ọdịiche nke ụdị ihe onwunwe. Ka ihe atụ, M400-D0 nwere enweghị nwekwara (D = 0), nke mere na akara na-eji na ala na mmiri n'okpuru osimiri arụmọrụ, nwere nnukwu mmiri na-eguzogide, njupụta na ike. Ciment M400-D20 bụ banyere 20% nke nwekwara nke belata ya njupụta. Ya mere, ndị ciment eji maka n'ala slabs, okporo ụzọ ọrụ, pavings nke ụlọ, okporo ụzọ na-emeghere slabs. Ma ika M400-D20-B yiri M400-D0 na ike ya, ma ngwa ngwa siri ike, ikwe ya iji n'ihi na mmepụta nke mesikwuru ihe owuwu.

The nọmba 400 na-akanye M400-egosi otú ọtụtụ kilos ciment na-anọchi obi tara mmiri ala kwa square sentimita. Na anyị ikpe - ọ bụ 400 n'arọ. The elu na ọnụ ọgụgụ, na elu ibu ọ nwere ike na. Cement na-awa ahịa ke akpa ma ọ bụ na nnukwu. The akpa ọnọ ewu ihe owuwu maka gụchara arụmọrụ, na nnukwu - na ihe osisi maka ulo oru eji. Otú ọ dị, e nwere akpa nke nnọọ nnukwu ike, nke nwere ike ịnabata ruo otu ton. Ha na-eji na-arụ ọrụ na ụlọ ihe na nnukwu mpịakọta.
