“…In stone powder S‐I, a clear and sharp peak at 463 cm −1 is observed, representing the presence of quartz mineral phase, 34 whereas in stone powder S‐II, a sharp peak at 1086 cm −1 has been observed, which can be attributed to calcite mineral phase 35 . In cementitious mixes, CSH is the major reaction product that contributes mainly to the mechanical and durability properties to the hardened product 36,37 . The raw materials to produce CSH may be supplied through two different source materials, namely, Ca‐ source and Si‐ source.…”

Expanding the capabilities of Raman scattering as an analytical tool for engineering applications can optimize the technological output immensely. Understanding the homogeneity of any blended mix is one such significant parameter in the family of composite building construction materials that needs an appropriate tool for its measurement. Raman spectromicroscopy has been established here for the purpose of studying the chemical homogeneity at the microscopic scale of a dry binary blend used in the building constructions as an example. In this study, two waste stone powdered materials, obtained from western Indian stone fields, have been characterized in their respective unmixed forms using Raman spectroscopy up to an extent so that the same can be developed as a microscopic tool to clearly “see” the chemical homogeneity of a mixture. A step‐by‐step study has been carried out by first, simply making a physically separated and identifiable boundary of the two materials followed by obtaining a Raman line image. The Raman line map could clearly identify the boundary, which otherwise was not possible to appreciate visibly. The same recipe has been extended to study the homogeneity of a binary mixture (blended in 1:1 ratio), using a Raman area map. The novelty of the work lies in the advancement in the analytical tool's family to see the chemical homogeneity of building construction materials at the microscopic level. Chemical imaging using Raman spectroscopy has been demonstrated as a simple tool to understand the homogeneity of the dry binary blend, which was not possible by other simple techniques. Using Raman area mapping proves to be a quick, valuable, and effective tool for measuring the homogeneity of the blended mixes at the microscopic scale and important for application in building construction materials.

“…Decreases of 40% in Young’s modulus and of 19% in compressive strength at 28 days were reported to decrease, respectively, to 28% and to 10% at 90 days, respectively, for concrete mixes with full replacement of coarse NA with coarse RA. With respect to durability-related properties, as stated, the use of RA from CDW generally leads to a higher porosity of the resulting concrete, thus increasing their water absorption [ 20 , 21 , 22 , 23 ], carbonation depth [ 22 , 23 , 24 ] and chloride-ion penetration [ 7 , 22 , 23 ]. Nevertheless, some authors also state that the pozzolanic activity promoted by the use of some RA may improve some of the durability-related properties [ 24 , 25 ].…”

On the Development of a Technical Specification for the Use of Fine Recycled Aggregates from Construction and Demolition Waste in Concrete Production

et al. 2020

The possibility of using recycled aggregates from construction and demolition waste (CDW) in concrete is rather widely agreed upon when it comes to the use of coarse recycled aggregates. However, this is not the case when fine recycled aggregates (FRA) are considered, as it is deemed that these seriously impair the behaviour of concrete. Hence, this work presents a technical specification proposal for the use of FRA from CDW in concrete, to attempt to fill this gap in legislation. The specification is based on a wide collection of experimental results, from which it is shown that for low incorporation ratios (up to 25%), the properties of concrete with FRA from CDW are comparable to those of a reference concrete. The intended international scope of the specification is ensured by the fact that FRA from CDW are typified by composition (percentage of concrete, masonry, glass, etc.) rather than by geographical origin or construction type. It is shown that, after typifying the FRA and assuming, as per design, the acceptable percentage losses (relative to a reference concrete) of mechanical, durability-related and long-term physical properties, if the maximum incorporation ratios proposed of each type of FRA are used, the variation of properties remains within the limits established.

“…9 shows that the partial replacement of normal aggregate with the CWA aggregate in optimum normal concrete at a value of 55% CWA aggregate. Siddique [30] in its conclusion revealed that the replacement of fine aggregates with ceramic waste aggregate up to 40% in structural concrete to provide considerable strength and durability characteristics. Rashid [16] concluded that a replacement of 30% aggregate of ceramic waste with conventional aggregates provides the highest compressive strength.…”

The utilization of ceramic waste is one solution to reduce environmental pollution due to development waste. The aim of this study was to utilize ceramic waste as a concrete aggregate material. The test consisted of the mechanical properties test of ceramic waste aggregates and the compressive strength test of ceramic concrete. The variation of normal aggregate partial replacement with the aggregate of CWA is 0%, 25%, 50%, 75%, and 100%. The total number of specimens is 50 cylinders. From the results of material testing and ceramic concrete tests showed that ceramic waste aggregate can be used as concrete aggregates, especially for elements that accept compressive forces, shear forces, and in-plane forces. The X-ray test shows that CWA aggregate is not pozzolanic, so it can be used as a concrete aggregate to reduce environmental pollution. The percentage porosity of ceramic concrete is smaller than the porosity of normal concrete. The effect of partial replacement of normal aggregate with the CWA aggregate in concrete optimum at a value of 55% CWA aggregate.
