Machine forward speed, vibration frequency of sawtooth sieve, amplitude of sawtooth sieve and sawtooth distance were selected as experiment factors. The response surface method was used, and the effect of each factor influenced on the targets of the residual film recovery was analyzed by drawing fourdimensional chip figure on Matlab2013a software.

Classifiion of Aggregates Based on Size and Shape ...
When the aggregate is sieved through sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this egory. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths, and 20mm size is used for high strength concrete. the size range of various coarse aggregates given .

Sieve Shakers
Sieve shakers are an integral part of aggregate testing to determine size distribution of the fines. These calculations determine an aggregate's susceptibility to movement and pore spacing. Also called gradation, this process separates individual particle sizes across an entire sample. Participle size distribution analysis is necessary to ensure that aggregates perform as intended for their ...

Importance of Sieve Analysis | Sieve Analysis of Aggregates
Sieve analysis is conducted to establish the particle size distribution of the coarse and fine aggregates. This is performed with sieving the aggregates according to IS: 2386 (Part I) – 1963. Here, various types of sieves are applied as recommended by the IS code and then the aggregates are passed through them and thus the particles with different sizes are obtained which are abandoned on ...

· Summary of Sieve analysis: A known sample of aggregate is placed on the top of the sieve set arranged in descending order. The set of standard sieves having the aggregates is manually shaked or by using an electronic sieve shaker for a specified time. The aggregate particle of different sizes are retained on specific size sieve due to the shaking.

Aggregates testing equipment | Matest
Mineral aggregates are a component of composite materials such as concrete and asphalt used to add strength to the overall composite material. For this reason, International Standards require several and precise tests on their properties. Like aggregates, rocks need special cares too: a rock stratum undergoes several alterations in case of excavations and handlings.
