Aggregate inotora vhoriyamu huru yekongiri, asi kwenguva yakareba, kune kusanzwisisana kwakawanda nezve mwero wekutonga mhando yeaggregate, uye kusanzwisisa kukuru ndiko kudiwa kwesimba rekumanikidza silinda. Kusanzwisisa uku kunobva pabasa rayo mukongiri, kureva, jecha nematombo, senge skeleton yemunhu, ndiyo yakakosha parameter kuona kusimba kwekongiri. Nokudaro, mabhuku akawanda ezvinyorwa uye mitemo yakawanda yemazuva ano uye zvigadziro zvichiri kuda simba rezvikwata kuti rive 1.5 kusvika 1.7 nguva, kana kunyange 2 nguva simba rekrete rakagadzirirwa. Munyori anotenda kuti kana yekutanga kongiri yekugadzira giredhi ichiri yakaderera kwazvo, ichi chinodiwa chinoiswa pamberi, ndiko kuti, silinda yekumanikidza simba reaggregate ndeye ≥40MPa, izvo zviri pachena kungobvisa iwo dombo nekuoma kwemamiriro ekunze sekuunganidzwa; Nekudaro, kusimba kwekongiri dhizaini yakagadziridzwa zvakanyanya, uye ichiri kutevera hukama pakati pevaviri pakutanga, izvo zviri pachena kuti zvakarambana kubva kune chokwadi. Asi izvo, iyo lightweight aggregate kongiri kumba nekune dzimwe nyika yakagadzirirwa uye kushandiswa kuinjiniya, uye silinda inomanikidza yeakareruka aggregate inoshandiswa ingori 15MPa kana yakaderera, nepo kongiri simba rinogona kusvika 80 kusvika 100MPa.

Imwe pfungwa isiriyo yakakosha ndeyekuremesa particle size inoshanda kune pumped kongiri kana self-compacting kongiri (SCC) matombo. Sezvo panofanirwa kuve nekufamba pakati pematombo mukuita kwemusanganiswa wakadaro uchifamba mupombi pombi uye uchiyerera mutemplate, iyo yakakora iyo dhaka lubrication firimu layer inodiwa pakufamba kwehukama pakati pematombo ane hukuru hukuru, ndiko kuti, zvakanyanya. pulp volume inogona kudiwa. Ichi zvakare chikonzero nei 19mm(British 3/4inch) iriyo yakakura saizi yematombo anoshandiswa mukugadzira masanganiswa akadaro kunze kwenyika. Kunyangwe iyo yakakura particle size yematombo anoshandiswa idiki, iyo void ratio inoda kuzadzwa mumusanganiswa yakakura, iyo iripo pachiyero pakati pemamiriro ari pamusoro apa, uye huwandu hwedhaka hunodiwa pakusanganiswa hudiki.
