The production of concrete, especially the contained cement clinker, causes a high proportion manmade gaseous air pollution. Studies show that decarbonation limestone effects roughly 8% worldwide CO2 emissions, which underlines need for action and research. Due to present building infrastructure stocks their obsolescence, or rather replacement, amount demolition material is permanently increasi...

Purpose – The purpose of this paper is to focus on optimization of recycling of concrete from lightweight aggregates containing expanded glass and hard polyurethane (PU) and on the issue of importance of environmental management in constructions, to produce the new combination using rest, construction waste of concrete from lightweight aggregates and hard PU new raw components of concrete from ...

One of the prime objectives this review is to understand role design parameters on mechanical properties (Compressive and split tensile strength) Self-Compacting Concrete (SCC) with recycled aggregates (Recycled Coarse Aggregates (RCA) Recycled Fine (RFA)). The considered for are Water Cement (W/C) ratio, Binder (W/B) Total (TA/C) Aggregate (FA/CA) Solid (W/S) ratio in percentage, superplastici...

The main aim of this research is to study the possible use of recycled fine aggregate made from waste rubble wall to substitute partially for the natural sand used in the production of cement and sand bricks. The bricks specimens were prepared by using 100% natural sand; they were then replaced by recycled fine aggregate at 25, 50, 75, and 100% by weight of natural sand. A series of tests was c...

This research investigates the static and cyclic characteristics of recycled glass (RG) as a supplementary material with concrete aggregate (RCA) in rail track capping layer. RG was blended by-weight RCA 10% increments up to 50% content. A performance-based laboratory testing scheme designed according field loading conditions layers tracks. Basic geotechnical properties + blends were evaluated ...

The construction industry generates a considerable amount of waste. Faced with this undesirable situation, the ready-mix concrete sector, in particular, has invested energy and resources into reusing its own waste in its production process as it works towards the goal of more sustainable construction. This study examines the feasibility of incorporating two types of concrete waste, which curren...

re area. In order to reduce the usage 99), Stone says that the 10mm recycled aggregate and blended stated that the use of recycled aggregate for the construction and rehabilitation of local government roads has a great improve in the last five years. C & D Recycling Industry (n.d.), the fact file stated that from the time of the Romans, the stones from the previous roads were reused when rebuil...
