Influence of Various Types of Waste on the Main Properties of Gypsum Based Composites for Thermal Insulations

open access: yesRevista de Chimie, 2019
In the last decade numerous research studies were performed in the attempt to recycle several types of industrial waste. This study has as main objective the obtaining and characterization of gypsum based composite materials with various amounts of industrial wastes (flue gas desulfurization gypsum and recycled rubber).

Achieving sustainable and durable concrete using high‐volume SiO2: Engineering properties, environmental and economic benefits

open access: yesStructural Concrete, EarlyView.
Abstract This study explores the potential of high‐volume amorphous silica (SiO2) replacement for ordinary Portland cement (OPC) in concrete to reduce carbon emissions. Amorphous SiO2, such as silica fume (SF) and CO2 mineralization‐produced Si‐rich gel, offers superior properties to concrete but is under‐researched for its use in concrete with high ...

FGD gypsum based composite for non-structural applications in construction

open access: yes, 2010
There are many by products created in industry that can be recovered or valued for the creation of new products allowing, in this way, the decrease of environmental damages caused by its disposal in landfills. This research work aims at the valuing of several industrial by-products, such as: flue gas desulfurization (FGD) gypsum from exhaust gases of ...

Material Properties of Basalt-Fiber-Reinforced Gypsum-Based Composites Made with Metakaolin and Silica Sand

open access: yesMechanics of Composite Materials, 2020
The effects of metakaolin (MK) and basalt fiber (BF) on the performance of gypsum-based composites were investigated. BFs 6 and 12 mm long were used in concentrations of up to 0.8 wt.%. Mechanical tests were conducted on both dry and water-saturated specimens. It was found that their flexural and compressive strengths increased with content of BFs to 0.

Strength of textile Composites [PDF]

open access: yes, 2006
For the prediction of composite strengths with representative volume elements (RVE) a thorough understanding of the ongoing failure mechanisms is needed. This again is influenced by the manufacturing process.

Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...
