The values for specific gravity, bulk density, solid density and apparent porosity averaged 2.75, 2.04 g/cm3 , 3.18 g/cm3 , and 13% respectively and they were within the internationally accepted range.
The values for linear shrinkage, permeability to air and thermal shock averaged 8.57% 69.4, and 29 respectively and these also were within the accepted limits.
This 40% sawdust addition was discovered to be the maximum under which mechanical strength and other refractory properties of clay will remain stable. Agha O A (1998) Testing of local refractory clay for producing furnace lining bricks. Key words: Carbon steel, strain, strain rate, Temperature, PID Controller, LQR.
while thermal conductivity averaged 0.493W/mo k with 0% saw dust and 0.134W/mo k with 40% saw dust thereby improving their insulating properties. Resulting tabulated performance indices showed a considerable improvement in settling time besides reducing steady state error.

The standard Arrehenious equation of 0.3% carbon steel is utilized to obtain an optimal deformation path such that the percentage of volume fraction recrystallization should be 1. Xia,"Microstructure and property of a medium carbon steel processed by equal channel angular pressing", materials forum volume 32 –2008, Edited by J. The presence of zone of inhibition clearly indicated the antibacterial activity of silver nanoparticles.
Atomic Absorption Spectrometer(AAS) was used to determine the chemical composition, while other established processes were used to determine other insulating properties like particle size distribution, specific gravity, bulk density, solid density, water absorption, apparent porosity, permeability to air, refractoriness, thermal shock resistance, modulus of rupture, linear shrinkage and thermal conductivity.
The chemical analysis showed that all the samples had high percentages of silica and alumina, thereby classifying them as Alumino-silicates.
