How to Load Calculation on Column, Beam, Wall & Slab ...

2021-8-27 · We know that the Self-weight of Concrete is around 2400 kg/m 3, which is equivalent to 24.54 kn/m 3 and the Self-weight of Steel is around 7850 kg/m 3.. ( Note: 1 Kilonewton Is Equal to 101.9716 Kilograms) So, if we assume a column size of 300 mm x 600 mm with 1% steel and 2.55 (why 2.55 so, 3 m column hight – beam size) meters standard height, the self-weight of the column is around 1000 kg ...

Properties of Concrete Blocks — Strength

Two blocks 6X8X9 inches, 22 months old, showed crushing strength of 2,530 and 2,610 pounds per square inch. These blocks were made of cement 1.25 parts, lime 0.5 part, sand and gravel 6 parts, and were tamped from damp mixture. It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per ...

PRECAST LIFTING AND FIXING SYSTEMS

2012-8-16 · Adhesion forces between the mould and the concrete vary according to the type of mould used. The following may be taken as a guide: Oiled steel mould q = 100 kg/m2 Finished timber mould q = 200 kg/m2 Rough timber mould q = 300 kg/m2 The value Ha of adhesion to the mould is thus calculated by the following equation: Ha = q x A*

Crushers

The crushing force is produced by an eccentric shaft. Then it is transferred to the crushing zone via a toggle plate system and supported by the back wall of the housing of the machine. Spring-pulling rods keep the whole system in a condition of no positive connection. Centrifugal masses on the eccentric shaft serve as compensation for heavy loads.
