STUDY ON INORGANIC COMPOSITE MATERIALS AS BUILDING MATERIALS

Assessment of radiological hazards of travertine rocks as building materials

Introduction: Although travertine is now widely used as a building material, the effects of its radiological hazards to public health should be a matter of concern. Therefore, this study aimed to determine its radiological parameters with regard to human health. Material and Methods: In this research 10 travertine samples were collected ...

Composite Materials of Thermo-responsive Polymer Networks and Inorganic Nanoparticles

The focus of this work is on composite materials of inorganic nanoparticles such as TiO2 embedded within microspheres of a responsive polymeric network. Microgels of N-isopropylacrylamide (NIPAM) with interpenetrating (IP) linear chains of poly(acrylic acid) (PAAc) were synthesized to promote the incorporation of TiO2. Dynamic light scattering measurements of the IP-microgels in aqueous environ...

Study on preparation of montmorillonite-based composite phase change materials and their applications in thermal storage building materials

Three composite phase change materials (PCMs) were prepared by blending butyl stearate, dodecanol and RT20 with an organically modified montmorillonite (MMT), respectively. After the three composite PCMs were characterized by DSC, it was indicated that the RT20/MMT composite PCM was a good candidate for building applications due to its large latent heat, suitable phase change temperature and go...

Estimating radiation dose from building materials

Background: Natural radioactivity in materials under certain conditions can reach the hazardous radiological levels. So, it becomes necessary to study the natural radioactivity in different materials to assess the dose for the population in order to know the health risks and to have a baseline for future changes in the environmental radioactivity due to human activities. Materials and ...
