Abstract The drive towards circular economy in achieving sustainable concrete cannot be overemphasized. recycling of waste tiles from the ceramic industry, demolished buildings, or during construction process could one way solving generated tiles. This study investigates use as coarse aggregates at replacement levels 0, 10, 20, 30, 50, and 100% by weight natural aggregate. Concrete cylinders we...

This paper outlines an investigation into the effect of incorporating rolled aggregate powder as a cement replacement on mortar mechanical strength and resistance against sulfuric acid attack. The study examined compressive strength, mass loss changes mortars based 10, 20 30% rates immersed in fresh water 12 weeks 5% solutions. Experimental results showed improved with 10 20% enhance to aggress...

The subject matter of the work presented here is development and evaluation novel lightweight mortars that meet functional technical criteria imposed on repair mortars. In a broad experimental campaign, lime, natural hydraulic lime–cement were designed tested. Lightweight aggregate, expanded perlite, granules from glass zeolite used as full replacements for quartz sand. hardened tested at ages ...

Abstract Waste ceramic tile (CT) powders are used to improve the workability, mechanical properties, and durability of self-compacting concrete (SCC). The waste CT powder is prepared by mixing construction tiles, sanitary fittings, electrical insulators, with different weight percentages mixed into SCC. Experiments have been conducted evaluate mechanical, optimum compressive, flexural, tensile ...

The use of recycled aggregate concrete is mainly negatively affected by its poorer mechanical and long-term properties. However, there are few structural applications for which aggregates can be used. In this case study, the possibility as massive external reinforcement wall verified. For application, most important characteristics freeze–thaw resistance, carbonation resistance then properties ...

Lightweight concrete (LWC) is used in the construction of partition and panel walls framed structures because it reduces dead load acting on structure. Rubberized lightweight aggregate made by using waste rubber tyre chips as a partial replacement coarse which increases ductility, toughness minimizes impact effect concrete. The presence content decreases compressive strength bond strength, affe...

The mechanical and durability properties of recycled aggregate concrete (RAC) are generally inferior to conventional due the old mortar attached surface original aggregate, which induces more complicated interfacial transition zones (ITZs) in RAC. microbial induced carbonate precipitation (MICP) modification is a novel environmentally-friendly method improve ITZs In this study, physical coarse ...

Oil Palm Shell (OPS) concrete can be used in different fields of construction. To determine more accurately the application, it is important to know and understand behaviour OPS over long term when aggressive environments. This paper presents results studies conducted on durability concrete. Water absorption capacity, electrical resistivity apparent diffusion chloride ions have been measured sa...
