Experimental study on properties of green concrete containing wood ash, silica fume, fly ash, and plastic waste

Science Progress, Journal Year: 2025, Volume and Issue: 108(2)

Published: April 1, 2025

This study aims to investigate the use of waste material combinations produce sustainable concrete. Wood ash (WA), silica fume (SF), and fly (FA) were used as partial replacements for cement in normal concrete (NCC), self-compacting (SCC), lightweight (LWSCC). Waste plastic aggregates partially replaced fine coarse LWSCC. Twenty mix designs tested flowability mechanical properties. In NCC, 10% SF replacement maximized compressive, splitting tensile, flexural strengths. Increasing FA (0–30%) WA (0–15%) contents reduced strength, although reductions relatively small acceptable. SCC, increasing with 20% slightly strength. Meanwhile, addition SCC flow However, all properties met guidelines developed by European Federation National Associations Representing Concrete (EFNARC), no visible blocking was observed during characteristics test. LWSCC incorporated 25–100% powder, 5% WA, SF, FA, 30% aggregates. powder flowability, density (below 1950 kg/m³); however, mixes remained within EFNARC limits. demonstrates potential utilization materials concrete, reducing natural resource consumption offering significant environmental benefits.

An Innovative Approach on Recycle Foam Concrete as a Sustainable Alternative with the addition of Nano Titanium Dioxide TiO2 on the Properties of Foam Concrete

Engineering Technology & Applied Science Research, Journal Year: 2025, Volume and Issue: 15(1), P. 19196 - 19199

Published: Feb. 2, 2025

Sustainability and construction waste recycling have become crucial topics today in response to the growing environmental challenges increasing accumulation of waste. Therefore, it is essential explore innovative solutions that improve sustainability concrete mixes. An effective approach use Lightweight Foamed Concrete (LFC), a revolutionary new material considered viable solution for reduction weight conventional concrete. This research focuses on study effect replacing 50% virgin sand by volume with Recycled Foam (RFC) crushed at four gradation levels aggregate sizes between 12.5-9.5 mm, 9.5-4.75 4.75-2.36 2.36-1.18 adding 0.5% Nano titanium dioxide TiO2 cement. The water-to-cement cement-to-aggregate ratio were maintained 0.45 1:1.3, respectively. Nanoparticles are incorporated into (FC) enhance its strength, due their beneficial properties, such as small particle size high reactivity. results conclude optimal RFC addition FC mixes compressive strength increase carbonation compared traditional

Experimental Analysis of Thermal Conductivity and Volumetric Heat Capacity in Concrete Incorporating HDPE Waste Plastic Powder as a Function of Temperature

Civil and Environmental Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: May 17, 2025

Abstract The objective of this study is to comprehensively investigate the influence incorporating high-density polyethylene (HDPE) waste plastic on thermophysical properties ordinary concrete, by partially replacing sand with HDPE powder. samples (cement, sand, HDPE, and concrete) were characterized using advanced analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), fluorescence (XRF). These analyses confirmed that incorporation powder does not induce significant alterations in internal microstructure composite material. Thermophysical measured a CT-Meter for various substitution rates (5–30% weight) at different temperatures (25°C, 30°C, 40°C, 50°C) thermoregulated box. results demonstrated progressive decrease thermal conductivity diffusivity increasing content. Furthermore, volumetric heat capacity increased as 5% was added, then decreased. This phenomenon observed all analysed, except 25°C. Moreover, into concrete significantly altered its properties, leading reduction performance.

Creating Sustainable Ultra-High-Performance Concrete (UHPC) Utilizing Recycled Glass

Civil and Environmental Engineering, Journal Year: 2024, Volume and Issue: 20(2), P. 1152 - 1161

Published: Dec. 1, 2024

Abstract Sustainable construction materials and trash reuse are effective ecological remedial solutions. Concrete is widely used in structural applications. Ultra-high-performance concrete (UHPC) a popular innovation with high mechanical properties. However, Portland cement large quantities, making UHPC expensive limiting its use engineering. Significant CO 2 emissions natural resource depletion occur. To make more environmentally friendly affordable, substitute PC mixture several additives. This study uses Ground Granulated Blast Furnace Slag (GGBS) waste glass (WG) at 0%, 10%, 20% replacement to create an eco-friendly cost-effective UHPC. accomplish this, 3 cylinders per mix were made separated. Experimental tests include slump, UPV, compaction factor, characteristics. GGBS WG improved workability, according the findings. For best workability properties, replace 10% of concrete. Using material additives as decreased compressive tensile strength.
