Meascán Coincréite Éadrom

A admixture coincréite éadrom is breiseán é a chuirtear leis an ngnáth-mheascán coincréite chun a chuid maoine a fheabhsú. Is féidir an meascán LC a dhéanamh as ábhair nádúrtha nó sintéiseacha. Úsáidtear go coitianta é chun meáchan na coincréite a laghdú agus freisin chun struchtúir chruach a insliú.

Is meascán de chomhiomláin níos éadroime agus maitrís scagach é meascán coincréite éadrom-mheáchain. Cuidíonn an maitrís scagach le struchtúr pore oscailte na gcomhiomlán a líonadh.

Mar chomhiomlán éadrom, Tá dlús toirte an-íseal ag LWA. Déanann sé seo an-oiriúnach le húsáid i gcoincréit éadrom. Ag brath ar chomhdhéanamh an coincréite lightweight, is féidir leis a neart a athrú, neart compressive, agus seoltacht theirmeach.

Is féidir roinnt cineálacha comhiomláin éadroma a úsáid chun coincréit éadrom a dhéanamh. Ina measc seo tá slaig, aolchloch, dolaimít, agus púicín. Go hiondúil, these aggregates are finely grained. Mar sin féin, industrially produced aggregates have been found to be better than their natural counterparts.

While a structural lightweight concrete has been designed with a density of between 800 agus 1200 kg/m3, it can be produced with a density as low as 600 kg/m3. A typical admixture coincréite éadrom can have a density of about 800 kg/m3 as well.

It is important to know that lightweight concrete is not standardized. Its design should be based on the needs of the project. Dá bhrí sin, you should be familiar with the various properties of each type of admixture coincréite éadrom.

Before placing any admixture coincréite éadrom, you should check for compatibility with the binder and the LWA. If the LC admixture is not compatible with the LWA, you should add it as late as possible.
