Selective Non-Catalytic Reduction (SNCR) can improve the denitration process and reduce NOx emissions by accurizing prediction of NOx concentration and ammonia escape. However, there are inevitable time delays and nonlinearity problems in the prediction of NOx emission. To reduce NOx concentration quickly in SNCR, excessive …

The fresh properties of concrete are mostly dependent on the fresh properties of its mortar portion; therefore, the mortar design can be taken as an initiative in the mix design of concrete. In the mortar phase of a concrete mix, the water content must be more than enough to fill the voids between the cement and fine aggregate particles.
