axis and the line
which contacts uniaxial compressive circle and tensile circle
in Mohr's stress test.

STRENGTH TEST
Testing for Compressive Strength
of Molded Concrete Cylinders
Testing for splitting tensile Strength
of Molded Concrete Cylinders
Test progress
- Universally used structural material.
- Complex material made out of cement, sand and pebbles etc mix with water.
- Strong against compression but weak against tension
- At construction site, any structures' facilities or architecture, need concrete essentially.
- Concrete is cheap, easy to get anywhere and form to any shape.
- Since, money needed in framed construction in modern structu

(1) 비중 : 성분에 따라 2.2~6.3의 변화가 있으나 창유리 등의 소다석회유리는 약 2.5이고, 석영보다 다소 가볍고, 연, 아연, 알루미늄의 금속화합물을 함유한 양에 비례하며 비중크기가 변한다. 창유리(2.54),크라운유리(2.49),칼리유리(2.39),연유리(3.77)
(2) 경도(hardness) : 다이아몬드 입자로 유
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
