The initial stages of deposition of calcium carbonate from tap water flowing in laminar regime through a rectangular duct were experimentally investigated using stainless steel and copper as contacting materials. The investigated time and temperature ranges were 1-28 h and 40-70掳C, respectively. The...

The magnetic flux density range of test equipment is 0.03–3.4T. The induction time is found to be reduced after magnetic treatment. In other words, the existence of magnetic field increases the nucleation rate of calcium carbonate. The effect of water velocity on induction time is not ...
The top bar is a mix of calcium carbonate and a middle temperature stoneware clay (equal parts). On removal from the kiln it appears and behaves like a normal stoneware clay body, hard and strong. However, pour water on it and something incredible happens: in a couple of minutes it ...
Three synthetized polymorphs of calcium carbonate have been tested in combination with the suspension of nanolime particles as potential consolidating agents for contrasting stone decay and overcome some of the limitations of nanolime agents when applied
The phenomenon of water treatment with an applied magnetic field has been known for many years and has been reported as being effective in numerous instances [1], [2], [3], [4], [5]. It has been established that the nucleation and crystallisation of calcium carbonate in hard water can ...
The geochemistry of calcium carbonate-rich sediments from a variety of environments throughout the Bahamas was investigated with particular emphasis on the factors that control the pore water chemistry. Most sediments are supersaturated with respect to aragonite, the most abundant carbonate component. Expe...
