Classification of aggregates based on size aggregates are available in nature in different sizes. the size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates. following are the classification of aggregates based on size: aggregates are classified into 2 types according to size.
Concrete is a mixture of cement, coarse aggregates, fine aggregates or sand and water. the approximate ratios of these components are as below: based on the ratios and the anticipated cement consumption in the country, the expected requirement of sand.
Costs include construction, operation, and maintenance. contractor bids on a recent wastewater project ranged from 150,000 to 400,000 for rotary drum screenings removal and from 150,000 to 208,800 for vortextype grit removals. generally, equipment costs will be close for each bid.
