A Study on the Practical Recycling of Ready Mixed Concrete ...

ABSTRACT. A waste sludge water produced from ready mixed concrete (remicon) factories may contaminate our environment, if it is discharged without any proper treatments. In Korea, all waste sludge water has been recycled in a way of mixing water of remicon, but the quality of the concrete can be deteriorated, such as slump loss or irregular compressive strength.

Uses, Benefits, and Drawbacks of Fly Ash in Construction

Mar 02, 2021 · When mixed with lime and water, fly ash forms a compound similar to Portland cement. This makes fly ash suitable as a prime material in blended cement, mosaic tiles, and hollow blocks, among other building materials. When used in concrete mixes, fly ash improves the strength and segregation of the concrete and makes it easier to pump.
