A SANDBLAST ABRASION TEST FOR SYNTHETIC AGGREGATE EVALUATION by James
نویسنده
چکیده
The need tor an aggregate abrasion test which effectively differentiates between the quality of aggregates of various unit weights prompted the development of a new test apparatus. The method selected uses air-driven sand as the abrading mechanism. Research findings based on tests of five natural and forty-seven synthetic aggregates tentatively indicate that the sandblast test is statistically reproducible and is characterized by improved differentiation between various aggregates when compared to results obtained with the Los Angeles test, ASTM C 131. Key Words-abrasion, sandblast, porosity, thermal transformation, synthetic aggregate, testing.

Background and Aim: The aim of this study was to investigate the shear bond strengthof composite to Emax porcelain using different methods of ceramic surface preparation (in vitro). Material and Methods: In this laboratory study, 36 porcelain disks were made and divided into four equal groups. The first group was prepared by sandblasting with 50 micron alumina particles, in the second group rec...
متن کاملEvaluation of Floorcovering Abrasion Resistance by Means of Image Processing Technique
An important factor in material quality is the time duration that materials are used (known as substance lifetime). Lifetime is a function of several factors, and among them wearing and abrasion resistances are more important than the other aspects. In addition, to the physical and mechanical properties, abrasion has a significant effect on the textiles appearance. This phenomenon considerably ...
متن کاملEffect of Synthetic Aggregate Thermal Transformation on Performance of Concrete
The investigation involved twelve different synthetic aggregates produced in the TTl rotary kiln, one commercially produced synthetic lightweight aggregate, and one regular weight aggregate. Each aggregate was used in concrete which was subjected to a variety of physical durability investigations including autoclave expansion, long-time reactivity, freeze-thaw, and shrinkage. From the results o...
