Loss on Ignition (LOI): fly ash loses weight when it burns at about 1,000 °C (1,830 °F) due to presence of carbon and water. The loss on ignition is the percentage weight lost due to carbon combustion and moisture evaporation. The lower the loss on ignition, the more durable the fly ash bricks will be. As per BIS it should not be more than 5%.
Fabric "weight" is often specified as mass per unit area, grams per square meter (gsm) or ounces per square yard. It is also sometimes specified in ounces per yard in a standard width for the particular cloth. One gram per square meter equals 0.0295 ounces per square yard; one ounce per square yard equals 33.9 grams per square meter.

The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
