What is the main property of steel and concrete that allows steel to be used to reinforce concrete
Similar coefficient of expansion
Compressive strength and concrete is about how many times it’s tensile strength
10
What is a size of a 10M bar
10 mm / 3/8
What describes a 60 grade bar
Hard, higher the grade the harder the steel
What type of construction use as welded wire mash for reinforcing concrete
Slab on great
Welded wire mesh is available in a sheet 6100mm long or 61,000 mm long how wide is it?
2.288 m. / 7.5 ft
What does yield mean as is applied to reinforcing steel?
Fails at that strength
How are l-shaped anchor bolts placed when great accuracy is not required
Their place by hand as soon as the concrete has been leveled and floated known as wet set
The building requires anchor bowls to be placed at
2.4 m on center this is the maximum spacing and most design engineer’s possessify a closer spacing of 1.2 m on center or left
Steel mesh comes in two common strengths
300 and 400 MPA
