Surface studies on acrylic bone cement.
Poly(methyl methacrylate) (PMMA) is used to fill the gap between the prosthesis and the surrounding bone in cemented arthroplasties. Biocompatibility problems related to bone cement application limit the clinical success of these cemented arthroplasties. Being the cement surface in close connection with the living bone, it is reasonable to assume that surface properties such as, surface composi...
متن کاملStructural studies on hydrating cement pastes
The development of the mesoscopic material structure during the hydration of ordinary Portland cement paste is studied by small-angle neutron scattering. Results on the time dependence of radii of gyration (Guinier region) and exponents (Porod region) are given and discussed. Introduction Building materials like hardened cement are heterogeneous. Their useful properties (as strength, porosity, ...
متن کاملThe Effects of Water/Cement Ratio and Air Entraining on Portland Cement Concrete Freeze/Thaw Durability
This paper deals with the issues of air entraining and water/cement ratio in Portland Cement Concrete as related to its freeze thaw durability. Practices have been in place for nearly thirty years which demanded high early strengths in Portland Cement Concrete pavements. This paper looks at those practices, investigates the correlation between water/cement ratio and air entraining, and presents...
متن کاملThe Effect of Cement Dust Exposure on Hematological and Cytogenetic Studies of Cement Workers
The study measured haematological and cytogentic parameters in workers occupationally exposed to cement dust in order to test the hypothesis that cement dust exposure may perturb these functions. Assessments of haematological, and cytogentic were performed in 30 workers occupationally exposed to cement dust and 30 matched unexposed controls. The RBC level has no significant change and WBC level...
متن کاملDetermining the water - cement ratio , cement content , water content and degree 1 of hydration of hardened cement paste : Method development and validation on 2 paste samples
7 We propose a new method to estimate the initial cement content, water content and free water/cement ratio (w/c) 8 of hardened cement-based materials made with Portland cements that have unknown mixture proportions and 9 degree of hydration. This method first quantifies the composition of the hardened cement paste, i.e. the 10 volumetric fractions of capillary pores, hydration products and unr...
