Answer 1

1. To carry loads- vertically
2. To support - horisontally
3. tightness
4. structure of surface
5. measurements - accuracy
6. Adaptation to production

Question 3

From a functional point of view forms for concrete can be divided into two parts, which ?

Answer 3

Load bearing

Supporting

Question 4

Answer 4

pg. 32

Question 5

What is a permanent form?

Answer 5

…

Question 6

The lateral concrete pressure on vertical, supporting forms is depended on some factors. Name and describe at least three

Answer 6

1. Rate of vertical placement of the concrete (R:m/h)
2. Concrete temperature
3. Consistency
4. Density of the concrete

Question 7

In some cases we say that concrete is fully hydrostatic what do we mean by that?

Answer 7

It means that the lateral concrete pressure will increase linearly from top ro bottom.
