2.7 Shrinkage
- Theoretical value: (a=35, : Maximum Shrinkage Strain Ratio)
- The process of finding 'a'
1. Arranging excel data
2. Finding 'a' with using a grapher program
(Converting Excel data into graph shape)
(Standardization of graph through regression analysis)-회귀분석을 통한 그래프 평균화
(Finding 'a' with using shrinkage equation)
3. Finding 'a'
strength obtained from tests of the double
axial loads P notation refers to the value
calculated by dividing .
Shear Strength
-An intersecting point of the shear stress axis and the line
which contacts uniaxial compressive circle and tensile circle
in Mohr's stress test.
2. METHOD OF CONCRETE
STREN
concrete refers to concrete tie that compression is strong but strengthen reinforcing rod to strengthen seal because is weak to seal.
(1) RC method of construction
Fig 7. RC structure.
If define RC method of construction breifly, because rubing cement and sand, gouge the interval and call method of construction to inlay reinforcing rod.
This method of construction that is called alias rein
concrete construction takes 30~35% if money takes in framed constructions, concrete is dense in construction fee.
- Stronger stress resistance in compression than other materials.
- Good Durability, Fire endurance, Water resistance, Insulation of sound
- Higher compression strength than other materials
- No limitation in shape or size(can form to any shape)
- Can make a particular strengt
