This paper aims to semi-quantitatively and qualitatively demonstrate ability of CO2 injection on microstructure and chemical composition of concrete, cement and recycled aggregate. The injection of CO2 into recycled aggregate creates CO2 Aggregate. Furthermore, the mixing of CO2 aggregate into concrete ...
1.1.1Composition 1.1.1.1Chemical composition The chemical composition of a material can be defined as the distribution of the individual components that constitute the material. The material can be apure substance, which contains only onechemical component; in this case, the chemical composition corresp...
Using an electron microscope, X-ray micro-diffraction and Raman spectroscopy, the researchers were able to map the distribution of elements in remaining Roman architectural works. What they found was significant amounts of tobermorite growing through the composition of the concrete, and a rela...
Therefore, to be concrete in our description, we will describe the practice of the present invention in connection with copper damascene or dual damascene processing including the use of Ta/TaN barrier layers. However, the present invention is not inherently so limited and other embodiments will ...

Chemical shrinkage of cement paste could result in the crack of concrete, which affects the volume stability and durability of concrete. In order to reduce the shrinkage performance of concrete, this paper discusses the effect of common mineral admixture(lithium slag, fly ash, steel slag) on the...
Our complementary suite of tools provides concrete information about the degree/extent of CSRO, atomic packing configuration and preferential occupancy of neighbouring lattice planes/sites by chemical species. Modelling of the CSRO order parameters and pair correlations over the nearest atomic shells ...
Glass fiber composition is so important because it may change the properties such as strength, elastic modulus and alkali resistance. Its most important property to be used in concrete is the alkali resistance. Some glasses of SrOMgOZrOSiO (SMZS) quaternary system, such as SrO, MgO, ZrO, ...
