Urea is the key nitrogenous waste product generated in the urea cycle in ureotelic animals.
Apart from that, urea and its derivatives are manufactured on a large scale for various …

Soil liquefaction is a major geo-hazard. As liquefaction could occur anywhere in a sand
layer and result in large-scale lateral spreading, treatment for liquefaction needs to be …

Given that acid-rich rainfall can cause serious damage to heritage buildings in NW China
and subsequently accelerate their aging problem, countermeasures to protect their integrity …

One-phase-low-pH MICP (Microbially Induced Carbonate Precipitation) or EICP (Enzyme
Induced Carbonate Precipitation) is a new biocementation method for soil improvement …

Enzyme-induced carbonate precipitation (EICP) is a potential method to improve the
mechanical properties of granular soil. The one-phase premixed percolation method using …

Calcareous sands have abundant intraparticle pores and are prone to particle breakage.
This often leads to poor engineering properties, which poses a challenge to coastal …

Microbial-induced struvite precipitation (MISP) is a new biocementation method for soil
improvement and hydraulic permeability reduction. Compared with traditional microbial …

Recycled concrete aggregates are greatly limited in applications due to the defects in the
adhered mortar. In this study, a novel bio-deposition method, enzyme-induced carbonate …

Either microbial or enzyme-induced carbonate precipitation (MICP or EICP) has emerged to
provide an alternative to cement-based ground improvement methods. For EICP, either plant …

Biocementation technology has recently become a new soil improvement method. In
majority of the biocementation processes, the formation of calcium carbonate occurs as the …
