This article describes the appearance, cause, & problems that may occur at cold pour joints in concrete foundation walls and occasionally floors or ceilings. A contraction joint is formed, sawed, or tooled groove in a concrete structure to create a weakened plane to regulate the location of cracking resulting from the dimensional change of different parts of the structure. An isolation joint is a separation between adjacent sections of a concrete. These joints are points where two separate pours of concrete meet, typically due to construction delays, changes in weather, or timing issues during pouring. Here's everything you should know about slab cold joints: What Are Slab Cold Joints? Slab cold joints occur when freshly poured concrete. But do you know what concrete cold joints are? A cold joint in concrete is an area or surface with a structural discontinuity caused by the delayed concrete pouring between two layers of concrete. These joints play a crucial role in maintaining the structural integrity and durability of the.

The Taiping Rebellion, also known as the Taiping Civil War, Revolution, or Movement, was a civil war in China between the Qing dynasty and the Taiping Heavenly Kingdom. The conflict lasted 14 years, from its outbreak in 1850 until the fall of Taiping-controlled Nanjing —which they had renamed. Taiping Rebellion, radical political and religious upheaval that was probably the most important event in China in the 19th century. It lasted for some 14 years (1850–64), ravaged 17 provinces, took an estimated 20 million lives, and irrevocably altered the Qing dynasty (1644–1911/12). Yet, unlike the Chinese Civil War of 1927-1949, it is hardly remembered in the West. The Taiping forces were run as a cult-like group called the God Worshipping Society by self-proclaimed prophet Hong Xiuquan, and. Copyright © Strata Foundation 2026.
