Crushed ravel or stone which is obtained by crushing of hard stone or gravel. Uncrushed stone or gravel resulting from natural disintegration of rock. Partially crushed stone or gravel which is obtained by blending of above two types. The graded coarse aggregate is defined by its nominal size i.e., 40 mm, 20 mm, 16 mm, 12.5 mm, etc.

M12 x 25 = 12 mm diameter, coarse thread is assumed (1.75 mm), 25 mm long. M12 is a matching coarse threaded nut. (To avoid confusion, we always include the thread pitch for both coarse and fine metric fasteners.) If you normally work with inch fasteners, pitch can be a little confusing—pitch is the distance between adjacent threads.

Since Sand is usually measured in cft = 0.0228 X 35.3147 = 1 cft = 46 Kg. Ans :- Cement consumption in 20mm thick plaster 1:6 for 1m2 plastering of brick wall is 0.11 bags (5.5 kg) cement. Cement consumption for 1m2 = 5.5 kg. So cement consumption for 10m2 = 55 kg. Cement consumption for 100 m2 = 550 kg.

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

How to convert millimeters to inches. To convert mm to inches you need to divide the value in mm by 25.4 as there are this many millimeters in an inch. For example, suppose you have a length of 100 millimeters and you want to convert it to inches: divide 100 by 25.4 which gives approximately 3.937 inches. To make the conversion easier, you can ...

Step-1: Calculate the dry volume of cement and Sand Mixture Required. Volume of plaster = Area X Thickness = 10 sq.m. X 0.012 = 0.12 cu.m. The wet volume of the mixture is always less than the dry volume. Dry volume of motor required for plastering = 1.27 X Wet volume of plaster = 1.27 X 0.12 = 0.1524 cu.m.

Beyond the primary stone crusher and secondary crushers, screeners play a vital role in the stone-crushing process by grading the crushed material by size. Screeners, or screening equipment, are integral to this process. They work by sorting crushed stones into various size categories using vibrating screens or mechanical separators.

The first considerations are at what point in the process the crusher will be used, the type of material, and the output required. Use the table below as a guide.

There are four basic ways to reduce size of a material: by impact, by compression, by shear or by attrition. Most crushers employ a combination of all these crushing …

The hot driven rivets of 16 mm, 18 mm, 20 mm and 22 mm diameter are used for the structural steel works. Unwin's formula gives higher values. Hence, adopt nominal diameter of rivet = 22 mm; Gross diameter of rivet = 22 +1.5 = 23.5 mm. Strength of rivet in double shear = Strength of rivet in bearing = D x t x p b = 23.5 x 16 x 300/1000 = 112.8 kN
