Ithini indlela yokubala ye-plasticity index of izitini ezikhanyisayo?

Indlela yokubala inkomba ye-plasticity yezitini eziphikisayo ukucubungula udaka lodaka lube yindilinga enobubanzi obungu-45mm, lubeke ku-plasticizer, futhi lucindezele ngamandla adonsela phansi kuze kube yilapho imifantu iqala ukuvela. Inkomba ye-plasticity yezitini eziphikisayo yizinga lokuguqulwa kwebhola lodaka ngaphansi kwesenzo samandla angaphandle, okungukuthi, umkhiqizo wokucindezeleka nokucindezeleka. Ifomula yokubala imi kanje:

Inkomba yepulasitiki S=(d－b)G

d——Ububanzi bokuqala bebhola lodaka, cm;

b——Ukuphakama kwebhola lodaka ngemva kokucindezelwa amandla adonsela phansi, cm;

G——Umthwalo lapho ibhola lodaka licindezelwa futhi kuvela umfantu wokuqala, kg.
