An Experimental Study of Human Hair in Concrete as Fibre

When M20 concrete with 1% hair is compared with the plain cement concrete, it is found that there is an increase of 10% in compressive strength and 3.2% in flexural strength. When M20 concrete with 1.5% hair is compared with plain cement concrete, it is found that there is an increase of 22% in compressive strength and 8.6% in flexural strength. B-30 Concrete - CR4 Discussion ThreadMay 18, 2010 · B30 it is concrete in Russian standard, probably.
