Structural kongiri M300. Key Features

Sezvo nguva Soviet, chesamende M300 ndiyo-chinja uye yakakurumbira zvose zviripo mavanga. Zvichienderana kuenda uye anochinja Zvinoumba musanganiswa inoramba kuzochinja chete chitsama esimende pa cubic meter, uye akaenzana vezvikwata mazana matatu, sezvinoratidzwa nezita muchikwata ichi nhumbi. The yasara zvinoriumba dziri kuchinja zvose hunhu kongiri: arambe achirema, mvura nemishonga, chando kuramba. Uyezve simende, sezvo filler anogona kusarudzwa norukangarabwe, reraimu kana girenayiti. Granite anopa mukuru chigadzirwa simba, mukurumari uye, naizvozvovo, chikuru mutengo.

Concrete M300 rinoshandiswa dzinenge dzose munharaunda. Rinoshandiswa private uye makuru okuvaka, pakuvaka zvivako, hwokugadzira uye mumaindasitiri hunhu, kuisa migwagwa uye anodzivirira ezvirevo. muchiso Izvi avhareji mu zvachiri, saka kwokudiwa nokuti guru kwazvo. It ndiyo yakakodzera chingaitwa kuvaka nheyo, achidurura monolithic zvivako, kuisa pamusoro pavements, twetsoka.

Concrete M300 GOST ane zvinotevera unhu:

1) Ratio simba B22,5.

2) Hazvizivikanwi mufambo - p2-P4.

3) Hazvizivikanwi mvura kuramba - W6.

4) The coefficient kuti chando kuramba - F150.

parameters ava zvakakwanira kuvaka kunzwisisa hurongwa sezvo mutoro inobereka uye asiri akatakura mutoro-zvinoriumba. Pfungwa yokuti chete kongiri kirasi zvingasiyana, zvichienderana nhengo yokuvirisa. Kunyanya kushandiswa lignopan B4 kana yavaibvisa nitrite muchando, uye plasticizers accelerators. Naizvozvo, kongiri M300 mutengo fluctuates kwazvo, zvakawanda zvinoumba vari musanganiswa, kuti zviri kumusoro. Uyewo, mari yekudyidzana sei seasonality. Somuenzaniso, muchirimo uye chirimo mutengo kongiri zvigadzirwa yakawedzera 20-25%. Naizvozvo inokurudzirwa kutenga zvose zvokuvakisa pachine kuponesa yakawanda mari. Paavhareji mutengo chete cubic mita rimwe makagadzirira kunovhengana ndiyo 3500 rubles. Mumwe bhegi 25 makirogiramu inogona kutengwa 200-250 rubles.

Zvikuru kushandiswa peskobeton M300 mudziyo zvindori matsime tsvina, vari mumamiriro ezvinhu akadai mukuru mwando, tembiricha kuchinja uye zvimwe nematambudziko zvinhu. The optimum reshiyo simba uye elasticity rinobvumira kushandiswa yaro zvaAtemisi monolithic Slabs uye uriri Slabs.

All kuvakwa zvivako kongiri uye dzimba nezvakavhenganiswa ichi vanoonekwa ne mukuru kusakara kurwisa mukurumari. Asi ichi chinogona kuwanika chete nokuita zvose zvaidiwa ezvinhu vari kuisira mhinduro. Somuenzaniso, kudzivirira paumbwe voids vari kongiri uchidururwa, unofanira kushandisa vibrating michina. Zvinokoshawo kuti chigone mureza nokuomesa musanganiswa: nechokwadi kuti pakanga pasina tembiricha akasvetuka, kurambidza kwemvura pamusoro mwaya mvura. Subject vose hwokugadzira nuances vanogona kuva nechokwadi chokuti kongiri zvakagadzirwa M300 ichava nguva refu kupfuura kwazvo ezvinhu.
