ASTM C1579 - 06(2012) Standard Test Method for Evaluating Plastic Shrinkage Cracking of Restrained Fiber Reinforced Concrete (Using a Steel Form Insert)
1. Scope 測試的內容
1.1 This test method compares the surface cracking of fiber reinforced concrete panels with the surface cracking of control concrete panels subjected to prescribed conditions of restraint and moisture loss that are severe enough to produce cracking before final setting of the concrete.

有沒有實驗室在測試?

查上述網址，沒有【認可實驗室】在測試ASTM C1579。
在測試什麼?
依據ASTM官網，ASTM C1579的測試是用來評估水份蒸發、粒料下沉、自身收縮等因素對於纖維混凝土在終凝之前與終凝之後數小時期間的塑性收縮裂縫開裂的影響。

1.1 本試驗將測試組各片纖維混凝土版表面裂縫開裂行為與控制組之纖維混凝土版作比較，控制組之纖維混凝土版係按照擬訂條件受圍束並促使水份蒸發嚴重到足以在混凝土終凝之前產生開裂。
1.2 This test method can be used to compare the plastic shrinkage cracking behavior of different concrete mixtures containing fiber reinforcement.
1.2 本試驗可用來比較各種不同配合比例之纖維混凝土之塑性收縮開裂行為。

大概是仇家找上門了，昨天被刪除一題，今天被刪除兩題，各扣 50點，共扣 150點。辛苦打字卻被刪，看來真的不能玩了。不知道這一題會不會被刪。
到下面的網址看看吧

混凝土測試可以問SGS或桂田,應該有在做.
