The utilization of waste fly ash in road construction is primarily confined to its use in embankment filling or as a stabilizer when combined with lime and cement. Its application in structural pavement layers, such as the base and subbase, faces a challenge due to the high volume of fine particles, which renders it brittle when stabilized. In this study, fly ash was …

and cement in the bricks. SOIL SELECTION . For a given soil-cement mix, strength can be increased by adding more cement up to a certain level. Given that the use of soil rather than river sharp sand has cost reduction as a major reason for such a choice, the use of additional cement stabilized bricks should ideally use less cement

To calculate the amount of crushed stone needed, multiply the length, width, and depth (in feet) of the area to be covered and divide by 27 to convert to cubic yards. The formula is: (Length x Width x Depth) / 27. How much area does a ton of crushed stone cover? A ton of crushed stone typically covers about 100 square feet at a 2-inch depth.
