S. Diamond and F. Lopez-Flores, Fate of Calcium Chloride Dissolved in Concrete Mix Water, Journal of the American Ceramic Society, 64 (11) (1981), 162-164, 1981.Diamond,S.,Federico,L. F.Fate of calcium chloride dissolved in concrete mix water. Journal of the American Ceramic Society ....
At present,a dominant viewpoint in concrete academic circle is that structural tightness(low porosity)should be the highest principle of concrete durability.So higher and higher volume of mineral materials(e.g.near or over 40% fly ash)was added to concrete to decrease the porosity.In this paper...
In addition, compressive strength, permeability and fresh properties were evaluated. In terms of sulfate attack, the performance of HCFA was significantly enhanced when slag was added to the mix, and the same was found for ASR. The high efficacy in resisting ASR of HCFA/slag blends was found ...
Understanding the shrinkage compensating ability of type K expansive agent in concrete. Constr. Build. Mater. 2016, 116, 36–44. [Google Scholar] [CrossRef] Le Saoût, G.; Lothenbach, B.; Hori, A.; Higuchi, T.; Winnefeld, F. Hydration of Portland cement with additions of calcium ...
The strategy is applied to the inverse model of the Shimantan concrete gravity dam located in Henan Province, China. Combined with the observed data and analytical methods, the optimal calcium leaching parameters are determined, and the curtain permeability coefficient evolution in a century is ...
Calcium not only builds the structures that support our bodies, many of us also live in homes built using structural concrete or cement made with lime (calcium oxide). Snails and many shellfish use another calcium compound – calcium carbonate – to build their own homes too – their shells....
% less energy and emits 14–28% less kg-CO2eq. than OPC-based concrete. The production of OPC-based concrete had the greatest negative environmental impact, except in the categories of metal depletion (MDP) and ionizing radiation (IRP_HE). In geopolymer concrete, the use of alkaline ...
Calcium formate improves the strength and workability of the cement mix, offering more consistency in quality of building materials. This enhances the performance of the structure in terms of integrity and durability. Calcium formate reduces the water absorption in concrete and helps in improving the ...
property, it can be applied to keep a liquid layer on the surface of the roadway, which holds dust down. It is used in concrete mixes to help speed up the initial setting, however chloride ion leads to corrosion of steel rebar, so it should not be used in reinforced concrete. ...
