It is well known that supplementary cementitious materials (SCMs) have obvious effects on the properties of concrete. In order to understand relationship between and ultrahigh strength concrete (UHSC), compositions UHSC were designed by simple-centroid design method. The investigated. was found incorporation silica fume (SF) improved flowability UHSC, but it decreased time acceleration period, ...

INTRODUCTION Direct compression is the process of tabletting of a blend of ingredients, the compression mix, without a preliminary granulation or aggregation process. The compression mix contains the active pharmaceutical ingredient blended with one or more excipients.1 It has been estimated that less than 20 percent of pharmaceutical materials can be compressed directly into tablets. The rest ...

Particle size enlargement is the process of transforming fine particles into larger particles by the introduction of external forces, and is a value-added step in many processes involving powdered materials. There are many different reasons to enlarge particle size, including increased flowability and improved product shape and appearance. With the multitude of options available to achieve enla...

The manufacture of highly drug-loaded fine globular granules eventually applied for orally disintegrating tablets has been investigated using a unique multi-functional rotor processor with acetaminophen, which was used as a model drug substance. Experimental design and statistical analysis were used to evaluate potential relationships between three key operating parameters (i.e., the binder flo...

This paper presents a method to develop Ultra-High Performance Fibre Reinforced Concrete (UHPFRC). Towards an efficient utilization of binders and fibres in UHPFRC, the modified Andreasen & Andersen particle packing model and the hybridization design of fibres are utilized. Particularly, the UHPFRC with ternary fibres is appropriately designed and tested. The flowability, mechanical properties ...

A novel single punch tablet machine was developed for a tiny amount of powder sample. This tablet machine mainly consists of upper and lower punches, single die, and conical powder feeder equipped with micro-vibrators. By using the powder feeder, mass of discharged powder can be maintained constant even if a tiny amount of powder having poor flowability is used. Motions of both upper and lower ...
