This study investigates the influence of aggregate grading on the expansion and damage of concrete due to ASR. Three mixes of concrete are compared with the primary variable being the coarse aggregate grading as: a standard composition as per ASTM C1293 ; a fine-dominant composition; and a coarse-dominant composition.

This paper discusses the effect of the aggregate grading and water/cement ratio on the air permeability coeffi-cient. An aggregate grading with more sand than coarse aggregates has resulted more beneficial from the point of view of concrete air permeability. This fact can be attributed to a denser skeleton formed by the finer aggre-gates.

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

With the development of mining industry, investors present various requirements of the features of flotation machine. Now there are many kinds of flotation machines, such as agitator flotation machine, pneumatic flotation machine and pneumatic- agitator flotation machine. And different mineral ores have different hydrophilicity, so the final configurations greatly depend on the professional designs.
Mobile crushers are loaded on their own crawler tracks or towed by truck horse when transported over longer distances to a new location. With tremendous flexibility and compact design, customers can take this machine directly to rock crushing plants or demolition sites for powerful, handy recycling of reusable construction materials, concrete debris, sand and gravel with economic efficiency.
The Mobile Cone Crusher (plants) has excellent mobility, it can move to anywhere with the change of raw material places or the construction places and start to work without building any foundation. Also it is easy to match with other equipments, meeting the different product requirements of different customers.
By absorbing the advanced technology from the world, we researched and designed PF series impact crusher. It can be used to deal with materials whose size below 500mm and whose compression strength less than 360Mpa. Thus, it is widely used in many industries, like chemical, metallurgy, road and bridge construction and sand making and so on.
Vibrating Feeder is a kind of linear-direction feeding equipment, in the mineral ore &rocks processing plants, it can send materials to crusher evenly and continuously. At the same time, it can screen materials roughly, increasing the practical handling capacity of the whole production line.
