Carbon black (CB) has been the dominant filler in the tire industry for decades. The demand for this petroleum byproduct is ever increasing, although petroleum markets can be volatile due to geopolitical issues. Finding sustainable, renewable substitutes for CB reduces the dependence on petroleum. Biochar is a renewable source of carbon that was studied as a potential CB replacement filler in ...

But for 28 days, maximum split tensile strength (5.2 N/mm2) was obtained from SF-IV type specimen which was prepared by 7.5% silica fume replacement for OPC. So, ultimately it can be decided that the partial replacement of 7.5% OPC by silica fume was found to be optimum and 33% split tensile strength was increased from control mix (SF-I) at 28 ...

The effect of partial replacement of silica or calcium carbonate (CaCO3) by halloysite nanotubes (HNTs) on the curing behavior, tensile properties, dynamic mechanical properties, and morphological characteristics of ethylene propylene diene monomer (EPDM) composites was studied.

Then strength parameter of concrete by partial replacement with silica fume has been studied. For the study, various cubes, cylinders, and beam have been prepared by replacing cement with 0, 5, 10 and 15 % silica fume. The result showed that partial replacement of cement with silica fume had a

use of nano silica 1.5%, 3%, 4.5%, 6%, 7.5% and 10% of constant rate of flyash as partial replacement of cement were studied. It was observed from the experimental study that concrete composites with superior properties can be produced using combination of nano silica and flyash.

Replacement of silica fume by fine glass powder (with a mean particle size diameter of 3.8 μm) reduces the maximum heat flow and total heat, due to fewer nucleation sites. The dissolution of fine glass powder releases high amounts of alkalis, which act as catalysts in cement decomposition and develop sharp heat of hydration.
