A Proposed Test to Determine the Cracking Potential Due to Drying Shrinkage of Concrete

The control of cracking is a problem that concerns those who design and build with concrete. But there hasn't been any standard test that evaluates quantitatively what the effect is on drying shrinkage cracking in the field when one material or condition is changed. Now a test is being developed that has been introduced for consideration by the American Society for Testing and Materials. Read more

Proposed Field Test for Drying Shrinkage of Concrete

Some of the many variables that affect the cracking of concrete are: materials and design; placing and finishing techniques; temperature and humidity; curing practices; ground conditions; and structural loads. Read more
