“…With the presence of air voids, the concrete becomes less in density and can reduce the dead load of the structures. Foamed concrete also reduces the structural cross section of the elements and foundation size [8]. Foamed concrete gives advantages, including the possibility of treatment and repairing, also better manipulation.…”

Self-Consolidating Lightweight Foam Concrete (SCLFC) is known as a concrete which has no requirement towards vibration or compaction effort due to its flowability and capability in filling and achieving full compaction in reinforcement. The main component in SCLFC is cement. Cement is a basic component of concrete that used in construction industry. However, it is also the main source of Carbon Dioxide (CO2) emission. If this component of concrete is replaced with other materials, it surely can help in reducing the emission of CO2. Limestone powder can be replacement with the cement content in SCLFC. Therefore, the aim of this paper is to determine the effect of limestone powder on SCLFC in term of flowability and compressive strength. The specimens were tested for compressive strength at 3, 7, and 28 days. The result indicated the flowability of SCLFC increase with the increase of percentages of limestone powder replacement. Meanwhile, the highest compressive strength of SCLFC containing 10% limestone powder replacement give better performance than the normal SCLFC. Based on the finding, SCLFC containing 10% limestone powder replacement can be categorized same as a conventional concrete hence it can be utilized for construction purposes. Limestone powder can also acts as an alternative replacement in concrete for replacing the cement.

“…coarse and 30% fine (ALEXANDRIDOU; ANGELOPOULOS;COUTELIERIS, 2018;ZHANG et al, 2019). Also, the higher porosity of the RA particles and the lower density of the clay-based and floating materials, which may be present, make the density of the RA lower compared to NA (GONZÁLEZ-FONTEBOA;MARTÍNEZ-ABELLA, 2008;MEDINA et al, 2014;NOVÁKOVÁ;MIKULICA, 2016;OMARY;GHORBEL;WARDEH, 2016), directly affecting the density of the concrete, which is related, in addition to the own weight of the structure, to the ability of the concrete to withstand stresses(SAYADI et al, 2016).…”

The recycling promoted by the processing of construction and demolition waste (CDW) and its production of recycled aggregate (RA), despite being a technologically known process and generating environmental benefits, still faces technical and economic barriers, which need to be elucidated and overcome, being a research gap. The research aim was to analyze the feasibility for the implementation of CDW processing plants. In the first stage, focused on technical barriers, from a wide bibliographic and documentary review, the parameters porosity, water absorption, density and resistance were identified as those that are most altered with the insertion of the RA in concrete production, determining that the previous classification and granulometric homogeneity of the RA influences the technical feasibility of its applications. Therefore, in the second stage, a case study was carried out to analyze the effects and magnitudes of costs intrinsic to the processing and viability of a plant, using data from Espírito Santo/Brazil. The main contribution was to provide instruments that support decision-making for the implementation of CDW processing plants, in order to identify that the rates applied to financing do not present significance to the total costs of the project when compared with other costs, such as transportation, promoting recycling.
