A commercial acrylic bone cement was modified by the incorporation of different weight fractions of glass spheres. The influence of the filler proportion on the mechanical behavior was assessed. Composite cements were prepared by replacing part of the powder phase of the cement by an equivalent weight of glass particles, which resulted in an increase in the liquid-to-powder (L/P) ratio of the p...

In recent years, UHP self-compacted concrete is an innovative category of that has attached a lot attention because its higher durability and compressive strength than conventional concrete. So, to overcome the cost preparation UHPC preservation high-strength deformation rheological characteristic self-compacting when replacing part expensive cement with three types production waste. addition, ...

Worldwide, vast amounts of waste are produced every year and most is sent directly to landfills or burnt, which has severe harmful impacts on the environment. Recycling materials considered visible solution protect Using scraps in concrete production a proper method for getting rid wastes, improving characteristics concrete, reducing consumption natural aggregates, can be used as cementitious t...

This research aims to develop glass ionomer cement for dental application. Several factors that possibly affect the mechanical properties of our developed glass ionomer cements were studied. Developed cements were investigated for their compressive strength according to ISO 9917-1:2007 in comparison with the commercial glass ionomer cement. The different particle sizes and pre-cementation of gl...

With the rapid development of construction industry brought by accelerated process urbanization, problem random stacking and landfill waste concrete can be seen everywhere, which seriously affects environmental health. The secondary utilization as recycled aggregate has become a research hotspot. This paper mainly studies influence cementing material system fine powder foam on water absorption ...

The effects of two types recycled micro-powder (concrete powder and brick powder) replacing part cement on the mechanical properties mortar were studied. results show that contribution concrete to strength is slightly stronger than powder. In a certain range dosage, performance close pure cement. When content less 10 %, compressive flexural will not be greatly affected: over 20% decrease signif...

In present research, the foam glass-ceramic composites fabricated by window glass, steel slag and SiC, CaCO3 foaming agents were investigated by press–sintering method. The optimum sintering temperature was obtained at 1200°C with a 3-minutes holding time and 20°C/min heating rate. The optimum pressure level of 80 MPa for achieving the 70 % of relative density was selected. The effec...
