Water reducers for the high alumina cement-silica fume system

Binders alternative to Portland cement and waste management for sustainable construction—part 1

“…159 This waste has been studied in only a few studies, mainly with regard to potential reuse in the construction industry. 157,[160][161][162][163][164][165][166] Management of the huge amounts of sediments coming from dredged activities is an important issue to be solved in many countries worldwide. Clean dredged materials can be used for construction fill, brick or asphalt manufacturing, topsoil and marine projects.…”

Binders alternative to Portland cement and waste management for sustainable construction – Part 2

“…197,201,202 Finally, attention must also be paid to compaction and segregation of plastics aggregates due to their low specific weight. 204 As reported in the literature, a viable strategy to avoid these phenomena is the use of fly ash or silica fume, 205,206 but also using some admixtures [208][209][210][211]212 (superplasticizers, air entraining agents, etc. ).…”

“…112,113,160,196–204 On one side, using plastics aggregates it is possible to obtain lightweight materials with a lower thermal conductivity, compared to traditional cementitious materials. 112,113,196–198,203,205 Moreover, several authors have reported an improvement of acoustic isolation and impact resistance. 181,196,197 The addition of plastics aggregates also leads to a compressive strength decrease.…”

Calcium Hydroxide Chlorides: The Ternary System Ca(OH)2‐CaCl2‐H2O at 25, 40, and 60 °C, Phase Stoichiometry and Crystal Structure

“…According to their composition x Ca(OH) 2 · y CaCl 2 · z H 2 O they are referred to as x‐y‐z phases. Their occurrence is often described in conjunction with dechlorination of waste flue gases, processes of the chemical raw materials industry, and concrete corrosion . As well as composition, a fundamental understanding of the conditions of formation and stability is required to control, or avoid, the occurrence of calcium hydroxide chlorides.…”
