① 소성수축 균열
시멘트-페이스트는 경화할 때, 절대체적의 1%정도가 감소하게 된다. 이에 따라 소성상태에 있는 콘크리트의 체적이 감소하게 되는데, 이를 소성수축이라고 하며 콘크리트에 부분적으로 인장력을 유발시키는 원인이 된다. 특히, 타설 후 외기에 접하는 콘크리트 표면으로부터 수분

if price elasticity less than -1, it is elastic, if price elasticity bigger than -1, it is inelastic. and if it is -1, is unitary elastic
the own-price elasticity of demand more simply referred to as price elasticity of demand,
the price elasticity of demand is Measuring how much quantity demanded changes sensitive to price change.

다. Amino Acid의 Titration과 pH buffer 작용
Amino Acid를 NaOH와 같은 염기로 Titration을 하여 얻어지는 Titration Curve는 적정하는 Amino Acid의 pH buffer 작용을 잘 설명해 준다.
즉 Amino Acid의 Carboxyl기는 Weak Acid이므로 NaOH-와 같은 Strong Base와 반응하면 일정한 pH 범위 내에서 큰 pH 변화를 일으키지 않는 pH Buffer 작용을 한
