Plum shall include black trap basalt of crushing strength of a minimum of 100 Kg /Sq.cm. ... The plums utilized are robust and contribute to the strength of the concrete.
Concrete Curing Time Chart – The 7 To 70% Rule
The curing process of concrete can take up to 28 days to reach 90% of its overall strength and if we take a look at this concrete curing time chart we can see.
Shear strength of plain concrete
Concrete shear strength as stipulated in standard codes of different nations is based on RC beam elements. Majority of research also focused on reinforced elements or on indirect shearing. There have been few studies performed on plain concrete subjected to pure shear. Hence, pure shear strength of plain concrete is not established.
